So I got this TV with not turning on symptom.
Using my backlight tester I confirmed that LED backlight is fine. Ordered a replacement main board TP.MS3393.PB851. With this replacement board TV turned on but original remote control will not work on a TV and side buttons are mixed up(for example if I press "Source" TV will increase volume).
So I swapped Eeproms and confirmed that it is a problem on my original main board, meaning with my original main board and an Eeprom from replacement board I got TV to turn on with not working remote and mixed up side buttons and the replacement main board with original Eeprom won't turn TV on.
So I used my CH341A to read the original Eeprom and it reads and writes back in it no problem. Now I have no idea how to fix that Eeprom dump file.
What puzzles me is the fact that model numbers of the main boards are the same.
How do I find a proper Eeprom dump for my models of TV and main board?
Or can someone please help me fix the Eeprom dump?
Thanks!
