The Toshiba DLP (HM/HMX) Owners Thread - Page 190

I am on my second bulb for my 62HM95, and have received the letter...My problem is after my first bulb blew I left the access door open for about two days. Thinking I should close it I did. When I received the replacement bulb FIVE WEEKS later, I noticed a very grainy picture on HD. When watching white backgrounds (especially Hockey on HDNET), it is extremely noticeable. If I shine a flash light on the TV when it is off, I can literally see strands of dust on the inside of the screen and strange circular images.

I have lived with it, and haven't had time to call in a tech..until I got no picture and a flashing red light (one second intervals), which means a bad BUS line, whatever that is.

Tech dude is coming out tomorrow, so hopefully he can address the BUS line and the grainy thing (maybe cleaning the lens or the screen will help the latter).

Oh by the way, the Optical Audio output doesn't work either.

At least I am getting the new bulb, right...

Hi Guys
I just bought a new DLP 62HM15A from costco about month back and here is the problem.

I connect the TV's HDMI port to a DVD (samsung upward convert) HDMI port...

the picture looks great but i have observed at least 3 times that the TV suddenly swtiches off with red light blinking continously. The green light is off.

I have to AC power off and restart.


I have also observed that the problem only has happened in the nights and I have not been able to replicate the problem in the mornings.

I have tried various outputs from the DVD player including 1080i and 780 P..but the problem continues...


The Toshiba service centre guy tells me it "may be" a firmware issue and he has ordered the part...god knows what he means..

Do any one of you have any experience /advice please..?

thanks

Thanks for the reply. I'll have to give them a call.

You do know the optical out for audio only works with signals from the built-in tuner. Doesn not work if source is anything else.

my local Fry's has the 56HM195 for $1999...

I found a buyer for a my ole (4.5 years to be exact) 57H81 and am looking to get a new set...

I bought a sony 42A10 for my XBX360 a few months ago and the picture on it is phenomal...even though the picture on the 57H81 still rocks, it is getting difficult to watch it when we compare the picture to the new sony...

I would get the 55A20 set, but it doesn't have a POP/split screen functionality which is a must have for us (actually for me, nice to watch two games at the same time).

For you HM owners out there, should I take this plunge at this price? Not sure if this set would have bulb issues or not...

GREAT Price!!! If that's in your budget, I'd say get it!!! I paid $2499 @ Amazon (best Authorized Toshiba on-line Dealer price @ the time) and received my set a week before the Superbowl!!!

I'm personally enjoying the glorious detailed, sharp HDTV broadcast & upconverted 480p > 1080i DVD picture!!! (Video REFERENCED Calibrated using Digital Video Essentials DVD)

Is it possible to arrange that the RCA audio outputs are still active even if the TV is off? When I'm streaming audio to my D-Link DSM-320, whose outputs go to the TV, I have to leave the screen on to hear the audio. I'd rather not waste the energy and lamp lifetime, but if I turn off the TV the audio doesn't get piped through.

pankaj123:

I have the *exact* same problem on my 52HMX85. It shuts off after 1 to 3 hours of use. If I then unplug it for a few minutes and fire it back up, it will shut off in about 30 minutes. I have to let it stand unplugged for a good 5-6 hours if I want to get 2-3 hours out of it...

I had it happen connected with HDMI with a Sony DVD player and a digital cable box. I haven't tried connecting it with component. It *seems* to be better during the day, but still shuts off regularly.

Local repair guy said 90% of the time it's a defective lamp... So I changed that, but it didn't fix anything. Since I just bought it, I'm returning mine to the store to get it replaced and let them deal with it.

Mine has a build date of February 2006.

Are you saying the 52HMX85 has that build date,or the lamp? P.S. O.K. Sorry,I googled that # and its a Canadian display. I guess Tosh is still making an '05 model "52. I just didn't snap, thinking if made in '06, would have an 86 model designation. Enjoy.....

Sorry to jump right in on this conversation but i just got a 46hm95 and I was wondering how to find out how many hours are on the lamp. I did a search on this thread and i couldnt find anything.

With TV turned on:

1. Press "mute" on the remote - 1/2 mute appears on the screen
2. Press "mute" on the remote again - mute appears on the screen
3. Press "mute" on the remote and hold the mute button -
4. Press the "Menu" button on the TV's front panel. "S" will appear in the upper right corner of the screen.
5. Press the "Menu" button on the remote and the "S" will disappear. On the left side of the screen you will see "RCUT" followed by RCUT
ADDR DATA BINARY
224DH 00H 00000000B.
You are now in the service mode.
6. Press "9" quickly on the remote and you will access the diagnostics page. In the right hand corner is the lamp time in hours.
7. Press "power" button on remote to exit the menu and power off the TV.

CAUTION: Do not use the up and down volume keys on the remote in this menu as it can alter the data and can be dangerous.

Since I did not get any response to my question for the last few days, I decided to take the TV back to Costco. Now I am looking at 72mx196 (at slightly lower price) and Sony KDSR60XBR1. anyone have experience with the 196 being less troublesome?

Just for your info....While the Toshiba's do have the POP feature, it can only be utilized when using two different sources. The split screen images CANNOT be from the same source. One source has to be a video source (HDMI, Component, Composite, etc.), the other must be an antenna source. Don't know if this is something you can work with. Because of this, I find this feature useless.

Hey everyone. I have owned a 62hm195 for about 6-7 months and have about 1000 hours on it. Recently I have been having a new problem of where I turn on the TV and then the cable box(connected via hdmi), I get white snow although the sound comes in perfect. To remedy the issue, I have to switch to a different channel (HAS to be different format, HD to non-hd or vice versa) Sounds like my TV isnt changing resolution correctly. Anyone have any insight on this? I thought I read someone here had a similar issue but I cant find it in any of my searches.

Update: I seemed to fix the problem by rebooting my cable box. My cable box must have been screwing up the tv even though it was off when I was getting the white snow. I have a Scientific Atlanta 8300 HD DVR box. Has anyone else had this issue with this combo or any other combo? Thanks.

I have a 56HM195 with an SA8300 HD DVR hooked up via HDMI. Occasionally when I turn on the tv I get what looks like a negative screen. It will be either blues or greens. I tried rebooting the cable box but it didn't always work. If I switched to an SD channel and then came back to the HD channels, the problem cleared. The cable box is set to default to NBC HD.

This weekend I turned the TV on and saw pink scrolling bands. I could see the picture behind them but the bands were about 4" high and the length of the screen. I changed inputs and channels and it was definitely the TV.
I unplugged it and plugged it back in and they were gone...


Didn't happen again all weekend.

Is this a light engine issue that others have seen?

I am on the 3rd lamp on this 52HM95 and it is barely 6mos old!

The issue I'm having with a 46HM94 and a DirecTV H20 HD receiver connected via HDMI is that the picture and sound blink in and out at about 1 second intervals if changing a channel brings about a resolution change - 1080i to 480i, for example. Only way to get it back is to unplug the TV for a few seconds. Component connection works fine. Wasted an hour on the phone with clueless Toshiba rep. "That's strange - let me thumb through my manual, very sorry, blah, blah, blah. Hmm...well, I dunno..." Pointless. Also tried 3 different receivers, different cables, reset routine on the set, etc. Repair guy is supposed to be here next week after a 6 week wait. I figure I'll wait to see what he has to say then decide if I'm just gonna drop it off back at Costco in exchange for a Samsung or JVC, or maybe that Akai set they have a screaming deal on at the moment.

I have had a similar problem. When trying to tune into some HD channels(mostly 720p) screen goes black but I have full audio. Nothing shows up till i switch the channel. I belive it is the cable box and not the tv.

It's not a problem with the cable set top box but it seems to be a problem with the Toshiba DLP. I've come across what you've been describing but this seems to happen when I switch to a HDMI connection (DVD). It's input number 6 and what I have to do to clear it up is simply switch inputs and all is well. It rarely happens but it does happen.

I am an owner of this model for about 3 months now, and have been trying to get the noisy lamp cooling fan fixed. From day one, I noticed a low buzzing sound coming from the TV. It is mostly noticeable during quiet segments of a movie, and is very distracting. For a $5K TV, it shouldn't make such noise. In all my years of building PCs, I have never heard a cooling fan sound like this. Since I bought the TV online, I couldn't easily return it for another one, so I called Toshiba customer service. I went through their standard unplugging/plugging the TV, and the noise remained. I got a service tech to come look at it, and he verified that the noise is indeed coming from the lamp cooling fan. He said Toshiba might consider it acceptable, but agreed with me that a cooling fan shouldn't make such noise. He went ahead and ordered a replacement fan under my warranty, hoping that maybe Toshiba has since replaced the part with a better model. Nope, the replacement fan was exactly the same when we compared the two, and it is just as noisy after he installed it.

At this point, I'm going to write Toshiba and express to them that the noise level of this part is unacceptable, and that they need to replace it with a quieter fan. The noise to me seems to come from the hub, and not actually from the amount of air it is moving through the fan blades as compared to a standard computer case fan. The fan looks to be a standard 120mm low profile fan, with a 3 pin connector, so surely Toshiba can find another supplier with a quieter model.

I hope this post will motivate other owners with noisy Toshiba DLPs to complain loud enough that they'll issue a recall. Other than this, and some slight geometry problems, I love this TV. The PQ is excellent, and I love watching 1080i HDTV of broadcast shows as it truly displays beautiful 1080p images. But the noise it makes prevents me from recommending it.

Hi I was looking at buying the 62HM195 OR getting a Samsung HL-S6187W. The advantage of the Toshiba is 12 bit color at a similar price, with an extra inch of display (Samsung is 61"). Do you guys have any suggestions before I put down my cash and buy this?

Well, it happened again! The bulb blew on my 62HM15A I bought in November at Costco on March 23. Toshiba shipped me a new SUPPOSEDLY IMPROVED bulb on March 24. It blew tonight, May 8. PLease tell me it was NOT one of the new improved bulbs!

Can you describe these geometry problems? I see NO defects whatsoever in regards to geometry on my set.

Don't

Well, the TV initially had perfect geometry. Since the tech came out to replace the fan, the image is now trapezoidal. Not by very much, but definitely noticeable when viewing 4:3 material. The top of the image is wider than the bottom. The tech is coming back to check it out, as I didn't notice this before the supposed noisy fan repair.

The tech is very nice, though he won't readily admit to possibly causing the screen to get out of wack. But I do know that he had to pull out the entire light engine to reach the fan connector. He showed me as he worked on it. When I called him back to tell him I now notice a trapezoidal image, he said he can't understand why replacing the fan would cause that. He said the light engine pulls out on a track, and that nothing should have gotten out of adjustment. Well, that may be his opinion, but nonetheless, he "touched" the light engine, and it's apparently delicate enough that pulling it out to replace the fan knocks something out of alignment.

So basically, my geometry issue is probably due to poor engineering on Toshiba's part in designing a TV that's difficult to service, or due to an error made by one of their authorized service people. I sure hope the tech can fix it, as I'm starting to regret trying to get a quieter fan replaced and ending up making my TV worse than before. If Toshiba won't recall the fan, I can live with the noise, as I've pretty much gotten use to it. I may try to replace it myself after it's out of warranty should I have the gumption to.

Would it be possible for anybody to post a picture of the rear of their 62HM195 Television? I'm considering getting one but am trying to work out dimensions/cable runs and types and would like to see actual placement of these components. I'm at work so I can't go run out to the store and look at one of theirs.
I tried searching here and google but had no luck...

Much appreciated!

Actually, from what I understand, this isn't really an issue with your TV, but actually a problem with micro-display rear projection TVs in general. You may not have noticed it previously, but all rear projection TVs such as yours has this problem with 4:3 material. From what I understand, this is due to how the engineers designed the projection system to accomodate a short cabinet depth. Less depth = more distortion on 4:30 material. On widescreen ratios, much less of an issue.

So, the tech is right, it isn't his fault, it is just the nature of narrow-depth rear projection TVs.

What order do you use to turn on the DirecTV box and your TV? have you tried to mix that up? This may be a strange HDMI issue.

He says there is a difference since the tech came.
