Hello, this is my first post here, so I hope I do it right.
I have a Westinghouse CW50T9XW set that's quite ill. I picked it up at a recycle shop for $20, hoping I could get it working and replace my smaller 720p set that I have now.
Anyway, here's what I've found so far and what I've tried.
TV will power on with panel buttons.
Backlight powers on.
No picture display.
Have been unable to check audio functions.
TV will power off with panel buttons, and back on again.
My diagnosis was a bad EEPROM, essentially the TV software was non-existent.
I scoured the web for the EEPROM and could not find one anywhere.
I then looked for a matching main board. I found one as advertised for the TV model, ordered it up to try.
Now, the original main board is a T.RSC8.10A 11153. The replacement was a T.RSC8.10B 12305. I had seen in another thread that these boards were interchangeable, but the other way around, so I gave it a shot. Still the same symptoms. Power, backlight, no picture, audio unknown.
So, then I removed the EEPROM from both main boards and swapped them. Same symptoms with both replacement and original main boards with swapped EEPROMS.
Earlier this week, I found a part matching main board, the 11153 board with a sticker on back showing 1A2G1741 - 000004843 AND V500HJ1 - L01 (panel number). Ordered it and got it in yesterday. Same problem. The newest board matches my original in every way, even the EEPROM is the same part number, but it appears as if the seller put blue paint on the EEPROM legs. Perhaps an old swaparoo preventive measure.
Anyway, I'm just hoping someone here might have a bright idea as to what else the issue may be, IF it's not the EEPROM.
OR
Perhaps someone knows where I can source the EEPROM for this board?
Summary.
TV works great except picture display and unknown audio function.
Replacement main boards have had same symptoms.
Main board part number T.RSC8.10A 11153 / 1A2G1741
EEPROM part number AE1210 / 25Q32S1P / E4E67
Pictures attached are all three main boards and the power board. Inverter and T-Con are hidden under the panel.
