Looks like a lot of tailoring needed for the cable, as it lists everything whether we are subscribed or not, and there is no logical order.

This update is an interesting anomaly. Yesterday, after seeing that the firmware update apparently "took" ( menu 2,4,7,0 Enter showed VLP33 008.32 ), I left TVGOS enabled and left the set off all night, which I had done previously after trying my first flash drive I received from Mitsubishi. This time the TVGOS populated, although channel order is quite messy and bizzare.

At this time I have no clue which update attempt ( probably over 12 ) accomplished the firmware upgrade. At no time did the TV blue status light blink for more than 1 minute. ( instructions say 3-5 minutes). At no time did a message screen pop up stating that "The software upgrade has been completed, etc. " Since I never got that message, I never bothered to check the firmware version until yesterday when I was getting ready to call Mitsubishi again to make sure I had all my info in order. Indeed , when I went into the TVGOS menu under "Setup", select Change channel display, 752159852, Enter, it showed packets streaming in on the proper status screen. Therefore, this morning, a populated TVGOS.

I just got a return call from Mitsubishi following up from my call yesterday and had to inform the Tech all seemed to be working properly at this time. I explained how my LT-46231 did not go through the steps indicated on the instruction sheet, yet still managed to update the firmware. I also informed him others on AVS Forum also had similar experiences.

I am glad TVGOS is now working , but this has been the weirdest firmware upgrade process I've experienced. I have hacked DVD players for region coding, downloaded ISO files and used a hex editor to "tweak" entries, burned ISO files to CD, and much more complex procedures than plugging in a flash drive with the power off and cold starting a TV with said flash drive installed. I have a Philips 26" LCD TV that had a similar upgrade procedure. I downloaded that firmware from a website, transferred it to the flash drive, and all went according to the instructions and status messages on that TV.

I just wish I knew which of the two flash drives I received actually accomplished the update. The second one that appears, "empty" when popped into my PC, or the one with multiple files that I received first? My guess is the later. Also, instead of unplugging the TV during one try at updating, I had the TV on with the flash drive installed, selected for "input" and hit the front panel reset.

Well, I've put in a firmware update due to my Host ID being invalid for CableCARD use. I just put in the thumb drive and as others have experienced, no flashing for 3-5 mins. Just the normal <1min. I've verified the thumb drive has the same content as Phase700B's first thumb drive. Or at least the descriptions match. The firmware still states VLP33 008.00. Host ID is still invalid. The firmware did not update. I am going to leave the thumb drive in for a while and see what happens.

You might try with the flash drive installed, powering up the TV, and after normal operation is verified , depress your input button and see if there is an input icon for "Card3" or some other icon that normally isn't there. This will be your flash drive. Select that icon (Card3, or whatever) and then depress "Guide". This should result in a blue menu box with white lettering and offer choices for mp3 play or jpeg viewing. With this icon still on screen, depress the front panel "system reset" button with a toothpick ( the button is just a small depression on the left side of your front panel adjusts and inputs.

The TV will now go through it's normal 1 minute boot up. When the blue light stops flashing, leave the TV alone for another 5 minutes. Then power it up, change the input to normal TV channel reception, and check your firmware version. If it hasn't updated, I have one more procedure that is a little more complex , but may update your TV. It would require copying your flash drive to a folder on a PC and moving some files to a new folder and copying this new folders contents to another flash drive to use for updating.

Everything is normal with the flash drive installed and no additional input added. Just for verification, the flash drive contains the pic attached.

This is identical to my 8/31 picture, except mine also had a TVGuide folder. My current state is the TVGOS is working, but the software version is still reads V33+ 8.00.

Has your cable card ever worked? Did you move it from another device? This message looks to me like a communication issue the the cable company. They have to match the card with the device. I'm not sure the firmware would fix the issue, unless there is some new cablecard technology. It took Comcast about 8 tries to get mine working. They finally figured out their signal was too hot.

This is a 46131 so the TVGOS would not be included and I speculate that's why there is no TV Guide folder.

As for the Host ID, this is for new cable service and never had CableCARD before this so I can't tell you if I could get a Host ID prior to this. Comcast says they need this Host ID to pair the card. Without it, they can not pair or match the card.

I still don't think your problem is firmware. The 231 has a single page on cable cards. Read your manual closely and don't skip any step. Unfortunately, the cable cards can vary significantly. Cable cards are notorious for being bad, and multiple cards may have to be tried. Do you have the cable card, and have you walked through the menus? Your Host ID has to be paired with the cablecard. If not paired properly you will get the error message. Good luck...

puttsthree, you rock! I just called and put my order in.

Good thing I randomly decided to check this thread last night.
post #2921 of 3041
So after numerous attempts to upgrade, the version # didn't change. The light would also only blink for about a minute (like a standard reboot). In addition, TVGOS doesn't appear to be getting listings (after a number of days). I called mitsubishi and they are sending another memory stick out to me. Hopefully that one will work better.
post #2922 of 3041
An Update. Got my 2nd memory stick today. Followed the upgrade procedure and it worked as per the instructions. The set turned on by itself and displayed the message listed in the instructions. The version number has been updated to 8.32.

I'll post back in a few days if/when my TGOS starts getting data.

Btw, I am pretty impressed with Mitsubishi on this. Not only has this TV been excellent for me, but to provide software updates on a TV that is almost 3 years old is really cool. The CSR even said that if this 2nd memory card didn't work, they would send out a tech free of charge to apply the update. Very impressed with mitsubishi.

I got my FW upgrade thumb drive today and when I tried it, it did not work, just like what others have experienced. I then copied the contents of the thumb drive to my own thumb drive. Then I tried it and lo and behold, it worked just like what the instructions said - TV powered back up by itself and dispalyed the message about upgrade having been completed and to unplug the powere, etc.

So I think the thumb drive was not making good connection to the USB connector on the TV and it is definitely worth copying to another drive to give it a try.

I did waste another hour with the two thumb drives I have received. The TV Guide is working, but the firmware version stands at 8.00. Set never powered on per the instructions. Mits Tech Support had no answers, leaving the case open but with no further action. I copied the content (identical on both drives they sent) just to keep, and will return drives to Mits. It is unclear to me whether any upgrade occurred to make the Guide work, or if it would have worked all along through the Cable feed.
The Guide is populated for both the Cable and OTA stations.
post #2925 of 3041
ANOTHER FIRMWARE SAGA: I called about a week ago and was told that there was an upgrade for my LT-46131, but it fixes CableCard problems, not the occasional lockups, reboots and other symptoms I saw, so I didn't need it, and there are risks. I asked, if I experience the problems addressed next year or in five years, could he promise that the upgrade would still be available. He couldn't, so he said he would send me the upgrade if I was willing to accept the risks. It arrived yesterday.

The USB flash drive contains less than 20MB of files and directories pretty much as described by others, except no TVGOS since my TV doesn't have that. I backed up the thumb drive to a directory on my hard drive, reread some posts here, disconnected my FireWire AVHDD, and then tried it. When I plugged the TV back in, the blue light flashed for about the usual minute and then … nothing. I waited for five minutes and still nothing, so I unplugged, pulled the thumb drive, re-powered, and checked the firmware version. It was still 008.00, so I came back here to read more.

I quick-formatted an old PNY thumb drive and copied everything from the backup on my hard drive to that, trying to put files on it in the same order as on the original (from a Command Prompt directory listing). I unplugged the TV again, inserted the PNY drive, and re-plugged. The blue light flashed for about a minute, then stopped. As I sat there for a few minutes pondering my next move, the TV came on! After maybe 30 seconds of TV show, the "software upgrade has been completed" message appeared over the video. I waited maybe another minute, turned off the TV, unplugged, and pulled the thumb drive. When I re-powered the TV and checked the firmware version, it said 008.02, which may have been what the support tech had said I would get. The PNY thumb drive was erased as part of the upgrade process. Of course I still have a backup on my hard drive.

SO, WHAT CAN WE CONCLUDE? Apparently the blue light doesn't flash for the whole time the upgrade is happening as the directions say. Would the original drive have worked if I had just waited a bit longer? I don't think so, because I think the TV turned on with the second drive in less that the five minutes I waited the first time. But I can't say for sure that it wasn't (say) 5.5 or 6 minutes the second time. The drive Mitsubishi sent is a Kingston DataTraveler 1GB formatted FAT32 with 16K clusters, while my PNY Attache 512MB is formatted FAT32 with 8K clusters. Could cluster size make a difference?

Kudos to Mitsubishi for making any kind of upgrade available for TVs several years old. But if this upgrade really doesn’t fix any of the problems I’ve had, I will be somewhat underwhelmed overall. Right now, I’m happy.

Just checking in here...good to see this thread is still going strong.
post #2927 of 3041
Hello everyone. So my 46231 is updated now for TVGOS and the Guide seems to be working just fine. Since I upgraded though, I can't seem to change the record quality (low-high) when scheduling a program for recording. I checked in the General tab within the program guide and it allows me to set low or high record quality, but when in the program guide itself, it used to show and allow setting the record quality when scheduling a TV program on the fly. Now the entry for record quality is blank and "grayed" out so I can not even make an entry there anymore. Not a big thing , but this used to work before.

Is there anyone else out there who has an IEEE 1394 AVDISK HDD connected up and in use since the TVGOS update? Thanks!

Well, our LT-46231 is dead. No lights and reset button does nothing. I have an extended warranty from Fry's so I will call them tomorrow.

Sounds like perhaps the power supply board or the DM board may have died. The LT-46231 has a place inside where a fan was originally designed to be installed. Digital TVs are essentially computers. Computers, even efficient ones, generate heat and usually have a cooling fan or large heat sink. The TV uses quite a bit of power even when off if the TVGOS is enabled. Since my 46231 DM board died, I have two low power DC powered fans running constantly behind the TV. I fastened some screen type fabric behind each fan to collect dust before the air blows it into the back of the TV.

The fans I used are from, guess where, Walmart. They are "O2 COOL" fans I got for $6 or $7 a piece and you can barely hear them operate. The fans come with an AC adapter or are battery operated. I use a 6volt AC adaptor instead to provide a slower fan speed that still provides adequate air flow. and quieter operation.

Just saying. . . I'm guessing Mitsubishi designed the internal housing over the DM board with a fan in mind, but probably didn't included it in the final units to be sold due to the fan noise, electrical noise it may have caused, or cost.

The Tech came today for the lack of power on. His reset worked when mine didn't. He said sometimes you have to unplug and then reset. He didn't even open it up.

He didn't have any luck with the software upgrade though.

While I had the set off the wall...

I copied the firmware contents to the computer and re-formatted the thumb drive using FAT32 and 4k clusters. Copied the contents back onto the drive. Installed the firmware upgrade. It worked, although the power on did take about a minute after the blue light quit blinking. Version is now 8.32.

Three folders were deleted off the thumb drive in the process. The TVGuide folder remained.

I am having a lot of issues with the cable card on a LT-46131, I contacted the cable provider and they told me it is a known issue and I need to update the TV firmware. I can contact Mitsu but I will not receive the package before NFL Sunday.
Anyone with a backed up of the files, can you please please please email me a zipped copy to wpenausa @ gmail com? Or a link where I can download them from. It will be greatly appreciated. Thank you very much.

So here is an interesting development. After upgrading the firmware I re-enabled TVGOS (as I posted above). I kept noticing that nearly every day when I turned the TV back on, it would give me the TVGOS message saying that I haven't set it up yet. I thought that was strange, especially since TVGOS never seemed to get populated. I have poor antenna reception (i need to buy a new antenna to put on my roof) so I merely figured that was the issue.

Then one day when the TV was off, I heard a click and saw the blue light blinking like a reset. I turned on the TV and got the TVGOS has not been setup message again. Monitoring the TV for the next few days, I noticed it kept resetting itself while it was off. I assumed this was due to the poor antenna reception messing with the TVGOS channel scanning. So I disabled TVGOS.

So anyway, FF to today and I'm watching CNN on FIOS (600) via cablecard and I hit channel down button instead of the volume down. TV immediately reboots on channel 599 (Cars.TV?). After the TV comes back up, I tune to channel 599 again, and sure enough, it reboots. Tried it 3 more times and it rebooted each time. So it appears as if scanning the FIOS channels caused the issues (perhaps..). I have never seen this on any other channels, but admittedly, I am mostly a TiVo watcher. Anyone else ever see this channel change/reboot issue? Especially anyone that upgraded their firmware?

Anyone know how to disable overscan on these Mitsubishi? I'm getting about 5% crop around the edges.

It depends on what the input source is I believe. If the signal source is a PC or some type of graphics card fed media server, then it may be a mismatch between the device output and the Mitsubishi native screen resolution. ? ?

Otherwise, how are the Mits working for you? You have two if I remember correctly? I still love th picture quality and color of this TV display.
post #2936 of 3041
I got a ton of overscan and washed out colors when I first tried to connect my new computer HDMI-to-HDMI on the Mits. Computer graphics card output is not the same as video STBs; the grayscale ranges differ and I think that timing might also be different; either that, or the Mits is expecting its other inputs to need the overscan. I bought an HDMI-to-DVI-D cable and connected it to the Mits' DVI-I PC input and everything's perfect (the manual warns you not to connect output from a computer to any other input). The PC that I replaced had a VGA output and I connected it to that same input with a VGA-to-DVI-A cable. Unfortunately the Mits can't accept a 1080p signal from any analog source so I had to use 720p from that computer.

Yes, I remember playing around with the DVI input vs HDMI and reading something about not using a computer hookup to any other input. I have connected two PC's temporarily recently using HDMI, but they were 720P and the image actually got cropped all around and was centered on the Mits display. I think Carlton is probably not using HDMI, but maybe DVI and when I used DVI it did not seem to have any overscan issues either. That's why I'm wondering if it's a graphics card issue or some kind of mismatch.

I have tried HDMI connects to a 37" Insignia 1080P and the video from my laptop fills the whole screen with no underscan or overscan issues. It gets displayed, of course, at 720p, but looks great on that TV. I think the Mits has some input and display limitations being an earlier HDTV.
post #2938 of 3041
I'm still happy with my LT-46131. I've had no problems with it, aside from overscan.

Overscan is enabled for all of the inputs (HDMI 1 & 2, Component, Antenna, Cable) except for DVI. It crops 20 pixels from each side of the screen. This is very common as it removes the video noise that is present at the edges of most analogue broadcasts. Except there aren't any analogue broadcasts anymore, so all it really does is remove part of what you want to see. Many TVs now are start to ship with zero overscan, or at least a setting in the user menu to disable overscan. Even more TVs have settings in the service menus to disable overscan. I'm hoping that there is a service menu setting for the Mitsubishis, but I'm not that familiar with the service menus.

FYI, it is now possible to have a PC output the exact same signal as a settop box. At least if you have the right nVidia 9X00 graphics card (not sure about ATI.) In the nVidia control panel, you can select TV output and the options are 720p, 1080i60, 1080p60, and 1080p24. You can also select the color space (RGB or YCbCr - you want YCbCr and 1080p60.) The only issue is that it is subject to the same 20-pixel x 4-side cropping as all other HDMI inputs/devices. It's possible to scale down the Windows desktop to account for this, but isn't not possible to scale all of the video overlay windows, so you still miss the edges in Windows Media Center and TotalMedia Theater Blu-ray players (for example.)

So, anyone know if Overscan is available in the Service Menu?

From page 18 of the LT-46231 manual:

8. PC-DVI
Do not connect a TV video source to the PC-DVI input. PC-DVI is a DVI-I input compatible with both DVI-A (analog) and DVI-D (digital) signals. Connect your personal computer's HDMI, DVI, or VGA video output to this
jack. An adapter or converter cable may be required. Please see Appendix B for signal compatibility. To hear audio from the computer, connect analog audio cables from the computer to the PC-DVI AUDIO jacks.

Note: The PC-DVI input is not intended for standard video from cable boxes, satellite receivers, or DVD players.

9. HDMI 1 and 2
The HDMI (High Definition Multimedia Interface) supports uncompressed standard and high-definition digital video formats and PCM digital audio format. For PC video, use the PC-DVI input instead.

Do not connect a computer to either TV HDMI jack.
Use these inputs to connect to EIA/CEA-861 compliant devices such as a high-definition receiver or DVD player. These inputs support 480i, 480p, 720p, 1080i, and 1080p video formats.

These inputs can also accept DVI video inputs. To connect a DVI input, use an HDMI-to-DVI adapter or cable plus analog audio cables. Connect the analog audio cables to the HDMI/DVI AUDIO inputs on the TV to receive left
and right stereo audio from your DVI device.

These inputs are HDCP (High-Bandwidth Digital Copy Protection) compliant.

These inputs are certified for proper interoperability with other products certified by Simplay.

The problem is overscan on the HDMI inputs and incompatible grayscale levels. As I recall, at one point a new setting was added to the Xbox 360 called "Reference Levels" to adjust the grayscale range, because some people were using computer monitors: "standard" for televisions and "expanded" for computer monitors (there's also an "intermediate" value; no one knows what it's for).

There's are four video settings on the Mits which only appear for the PC-DVI input: Auto Position, HorizPosition, VertPosition and Fine Detail (for analog VGA signals only). I used Auto Position to zoom and center 720p VGA from my old computer; neither Auto Position or Fine Detail appear for the digital signal from my new computer.

Perhaps your Insignia display can sense what kind of video (PC or television) is being sent to it and adjusts itself accordingly.
post #2940 of 3041
The HDMI inputs crop the picture for all of my HDMI devices. My TiVo HD is cropped. My Blu-ray player is cropped. My Xbox 360 is cropped. This problem has nothing to do with a PC.

Is there any way to adjust overscan in the service menus?
