Ok, my turn.
Purchased two Westys in 2008, 42" & 47", TX-42F430S& TX-47F430S.
(Posting from work, so not sure what hardware / firmware - can get that later)
Both worked great until Nov 2010, the 47" develops the "amber - no blue LED" symptom. 42" still working great.
It powers on, amber led, WHITE "W" boot logo on screen for a few seconds, then screen goes out, and amber LED stays on. I try multiple 10 second reboots, unplugged for days, etc...nothing.
I have a 5 year PP, so I get a tech out, and he diagnoses a dead panel/inverter.
Tells me 2 days later he can't get the part, so it cant be fixed.
Warranty people have me buy a new TV and send me a check for the original purchase price.
I ask them what to do with the old one, and they say keept it, trash it, do anything I want. So then I decide to try and fix it since I doubted the panel or inverter were bad, and it couldn't hurt to try.
After a few days of searching, I found ekztal awesome post here with the v1.4.0 edited firmware.

I try it last night.
sandisk 4gb cruzer, format to Fat32, drop the zip file AND the un-zipped files as well on the root directory and flash in the following manner:
1. With the power cord removed from the back of your Westinghouse TV, insert the USB thumb drive into the service port.
2. Plug the power cord into both the back of the TV and the wall outlet.
3. The Power LED indicator starts out amber; after 20-30 seconds, it turned purple-ish with slight flickering; I check back five minutes later and it is solid blue.
6. Once the Power LED turns blue, I unplug the set, remove the flash drive, and plug it back in and turn it on.
BAAM! The TV comes on with the new boot logo and fires up with a picture from the TV tuner (connected to cable) a few seconds later.
All is great, EXCEPT I HAVE NO SOUND. I check and double check all the audio settings, check multiple inputs and sources, and still no sound.
I tried to re-flash it was stuck on yellow again. I'll try more re-flashes after work.
My main question is, does anyone know what happened to the sound, and can I get it back? Anyone else have this issue?
Second issue is tracking down all the firmware is a pain, so I uploaded all the ones I could find, and have linked them below. Please search the thread with the file names to see if you should use them.
Link to 42 LPL LX v1.2.0.rarLink to TX-42F430S - v1.4.0 - editted.zipLink to SusanII_v1.3.0_20071026.rarLink to SusanII_v1.6.3.rarlink to 01_OSD_FW_V1.4.2.rar firmware.
Hopefully this post makes it easier for anyone else to find info on the TVs and tracking down firmware.
If I can get set up and running again, I'll be so happy that i need to buy someone a beer or make a donation here

Even if I cant get the sound back I'll be happy

Please post any info that may help me and thanks in advance.
EDIT: I added the new firmware I found, and I STILL HAVE NO SOUND. Any Ideas?
