TX-47F430S Firmware

There's the link for the listed TV model's firmware. I just wondered if it would be possible to get a firmware that would fix the problem with this model not passing 5.1 audio from the OTA tuner? Other than that the firmware seems to be just fine for it.

I also have a TX-52F480S & I can't get it to handshake (hdmi or hdcp, I'm not sure which) with my denon 2308CI... it constantly switches between detecting, snow, and brief flashes of the correct image. (Thread describing the issue here: http://www.avsforum.com/avs-vb/showthread.php?t=1141032 )

I've been in touch with both Denon & Westinghouse support & both told me to replace the others device with something else & that there was nothing they could do to solve the problem & that they had never heard of anyone else having any issues with these specific devices.

Does this sound like something that could be solved with your custom firmware?

Is there anything I can do to help progress this project? I also PM'ed you with my email since you said that you are only providing firmware updates when requested.

Dear Saguratus,

Is the information about the chipsets and software for different models available online anywhere or is it possible for you to post it here sometime? I don't know if it would be all that helpful, but it would be nice to know what models you have found that use the Trident Chipset.

Thanks,
Drewtwo

I believe the TX series uses the Trident Chipset. Not sure about the others..

It would be AWESOME to see custom firmware for my 32H240S.

keep us updated.

I also have a TX-47F430S and saguratus is correct.

This is Trident hardware with a version of Linux 2.4

I have found out that there is indeed a serial port on this unit somewhere because the firmware upgrade inits it.

I would guess that for the bricked units, one should be looking for this port in the unit. My guess is that the serial is TTL so some level conversion would be needed. Would be strange to have a standard serial nowadays.

I also noticed this line:
# config multi-func pins as GPIO for HDMI port
I don't know if the HDMI is being handled by GPIO (would be strange) but it at least we should have a port for configuring the chip. Might solve some issues.

saguratus,
I would recommend that your boot image use something like the compatible.sh in the firmware. You could then release to know versions and add to this file as needed. I haven't seen your work yet, but it may work.

Thank you and good work so far.

Just uploaded the TX-42F430S firmware version 1.4.2 from the official westy site for you.

Thanks for your work.

Is it just me, or does anyone else have a concern that we have not had an update post from saguratus in a month and Trident was releasing the code to him.

I hope he is okay.

It would be nice to know who he is dealing with over at Trident so we don't need to start from scratch. I don't see any postings on their website about the code.

Okay, did some messing around light night. Tried to get a dump of the current software by modifying the shell scripts on the firmware update, but without a console, it is difficult to see what commands are working or not working.

The hardest part is the mtd device. It seems to be a collection of partitions, and not just a single cramfs. It seems that root is located on /dev/mtdblock2. I was trying mtd0, so that might make a difference. Regardless, I haven't gotten into the drive though.

I did notice that Sam Sheng seems to be the developer on the project. There does seem to be a Sam Sheng who does this type of dev work on the net, not sure if it is the same guy.

"/home/samsheng/Projects/kernel_cx/include/linux/dcache.h"

I also noticed that the directory is kernel_cx. It is interesting to note that Sony has the kernel_cx listed on their open source list for their display as well. Seems Sony is ahead of Westinghouse in keeping legal.

I will let you know if I find out more.

I have a SK-26H520S, running smoothly. If you need any firmware testing or whatever, I can help. I don't really care if it ends up bricking to the point of being unbrickable as long as it contributes to the cause. Not to say I'm rich and can buy another, it's just that this TV was handed down to me and I have no real attachment to it. However as long as it does work I'd like to keep my hands on it

I was wondering I have the TW50601 C032A, SK 32H240S brick. I have no issues with the power supply and it was the MCU that isnt working. Is it possible your firmware has an ability to autorun when inserted to reset the MCU/Cramfs(ACM-328). Since it is a brick if you want to send any test firmware for the unit I'd be happy to try it out. I'm at the point where I am willing to try just about anything since westinghouse isn't bothering to return calls or emails. I've pulled the set apart a few times already to study the boards to see if there were any jumpers that might be able to reset the MCU but I cant find documentation on that subject.

Any help/firmware would be appreciated, thanks.

As for the serial number issue, it's a known issue at westinghouse. I was informed that they are in the process of manually entering all serial numbers, and to check back in a few months to see if my serial number had been entered. When asked if they had an expected completion date for the website support, I was told no. It took a number of calls to get that information out of a service rep.
Sadly I have two westinghouse tv's and one of them was actually in their system, whether the firmware was the correct one for my unit, I have to wonder as the updated one is now a doorstop.

Do you have any information on where these reader/writers might be found and how to determine what type to buy if its even possible or is it just a pipe dream and I should just buy a mercedes because its cheaper?

Ok, I am officially an idiot.
I tried to upgrade my TX42F450S with the firware for a 430.
Result: the unit turns on but the ONLY thing I see is the amber power light that's it.
Is there any way out of this or am I officially hosed?
If I am officially hosed what are my options? Send the unit to Westinghouse?
I also tried to find the official firmware but the Westinghouse site does not recognize my serial #

I would appreciate any helpful tips, I already know that I am an idiot no need to post that again here

Does anyone here have a thumbdrive boot method for copying the existing firmware in a Westinghoue TV? I've got multiple units of the same model with different firmwares. Unfortunately, the current firmware from Westinghouse does NOT play DVDs properly. It chops off what it considers the overscan, as if the screen were a CRT, not an LCD. The particular model is SK-32H590D. I have one with firmware 1.00.11 micro version v08 which plays DVDs properly. Tmore units with more recent firmware are the problem.

Ok somewhere in the 200 pages on the westy tx thread. I could never find any firmware to get my TV back working. I have a TX-47F430S That just went to sleep one day. It comes on with the big W and then goes to the amber sleep light. Is there a firmware that would get me back on again WITH problems. Until something happens here to make good firmware? Thanks.

Search for my posts of username I have posted the last good firmware for the 47" which was 1.3.0 and a link to download.

The file I found for 1.3.0 is (SusanII_v1.3.0_20071026.rar)
ok I found that thanks. But it is a .rar file? I have no idea what to do with that. I still need someone to hold my hand. Once I get it on a usb drive I am not afraid to do anything to the TV it has been in the original box for about a year now. I am going to buy a new thumbdrive. how big?
Thanks for the help.

Carsfanatic... I figured out how to extract and read some of your other posts. I will try tomorrow and see what happens. thanks.

ok so i formatted new thumbdrive. extracted the two files to the drive. Then put in the TV and plugged it in. It looked like the Thumbdrive was being read. then it looked like the drive went to sleep. But nothing ever happened on the TV just the orange light. Do I unplug tv and try it now?

It should eventually get a blue light when it is done and has been successful. The orange light means that it has failed for one reason or another.

There is of course a chance that since the TV was already messed up it is unrecoverable and the only way to fix it is to buy a new TV or replace the board inside the TV that holds the firmware and then it should work and you would have whatever firmware that was contained on the new board.

Yeah I figured it was worth a try since it was just sitting there in the box. But It doesn't do anything after about an hour. So broke broke. It was worth a try.

Hey, can saguratus or someone tell us how to change the startup image in the firmware like he did in his screenshot on the first page of the thread? I think it'd be a blast to hack a custom image of our choosing for TV startup.

Thanks for any advice!

I'm going to agree with dizzie. I think this is a great idea. Custom Startup Images.

I'd be really interested in this as well. Here is the direct link for the Firmware download for a SK-32H240S from Westinghouse:
207.38.27.164/firmware/SW/SK-32H240S_X241.rar
(Perhaps by playing around with the URL/dir structure, firmwares for other TVs and/or different versions for this one may be found.)

And here's an interesting converstaion that I had with Westinghouse's support last year:

-------------------

Hello. I'm trying to figure out if the firmware on my TV newer than the one that is currently on your web site (SK-32H240S_X241.rar) ?

The Model Number is: SK-32H240S

The current firmware on the TV says:
F/W version: V2.01.019
TVMicron version: M2.33
PMon version: P2.10

But the firmware upgrade that I downloaded from your web site (SK-32H240S_X241.rar) says the following:
Software: V1.01.019
TVMicro: M1.32
PMON: P1.10


Did I download the most recent firmware available for this TV?

-------------------

[[[REPLY:]]]


According to the information you provided to me, the download on the
website is an older version of the firmware. The version on your
television: F/W version: V2.01.019 is newer.

If you have any further questions, you may contact us through email, or
by calling us toll-free at 1-866-287-5555, between 9am and 9pm Eastern
Standard Time, Monday through Saturday. One of our technicians will
assist you.

The TV I bought was from Buy.com and was refurbished. According to their support tech it already has a newer firmware on it than the 'latest' one available on their web site. If anybody knows of a way to dump the firmware that's currently on a Westinghouse TV back to a USB drive, I'd love to hear how. I also wonder why they wouldn't post the newest firmware on their site (and what would happen to my TV if I 'downgraded' to the 'latest' firmware available on their site.)

I found a way to change the start-up logo, I made a thread here if you're interested.

Really good NEWS, now have **** access to BUILTIN SERIAL PORT ****

I got my hands on a TX52F480S semi-bricked (amber led).
No matter what I was trying (different FW, editing scripts..), nothing was working. TV was accessing the USB key for a little while but no led blinks and never got the blue led.

While reading on all the posts, I came across someone that was mentioning the existence of a serial port on the board. So I digged around and found the way to connect.

Details are as follow:
you need to use a TTL level converter to convert for 5 volts signal to RS232 signal (like IC MAX232). You connect the converter (RX, TX and GND) via the 5 pins connector CN3. Pinout is:

1- ?
2- GND (to converter GND)
3- TX (from converter to TV)
4- RX (from TV to converter)
5- +5 Volt (can be used to power the converter)

Please check with a multimeter to make sure you have the correct pin 1 (not written on the board, but looking at the back of the tv, it will be on the left side).

I used a terminal emulator (an old Telix) to connect, I've set the port at 115200,N,8,1

I am really not a Linux guru, but I did found that 4 blocks out of 5 are corrupted on the flash chip. MTD0 is ok. The flash is using JJFS2 file system. There is way to recreate these blocks from another good TV. So once a couple of you guys are connected to your TV, I'll ask for these blocks!

So now it is time to really get in control of your TV!
I am 90% sure that all those bricked TV will come back alive.

Pictures and schematic to follow!

That's great news! I find it hard to believe I'll ever unbrick my WH, but it's awesome that you're making progress and hopefully some people who read this forum will be able to learn from the progress you're making.

I consoled to my TX47 some time ago to mess around with the mpeg libs and cross compiled several test kernels because the source is availble everywhere (MontaVista Linux) because its the same kernal used in many routers, voip devices and even the PS2 I think.

mtd0 is the same as the /images/mtd0 floating around in the firmware updates so just grab it and dd if=/images/mtd0 of=/dev/mtd0 (or use flash_burn thats included. Also the only block that uses JJFS2 is mtd3 witch is mounted to /etc. I'm guessing they used that fs because its r/w. mtd4 is mount to /mnt and is cramfs alone with the rootfs.
