These main boards can have multiple failures, in addition to the EEPROM.
If EEPROM replacement does not repair your board, there are likely additional problems.
Symptoms EEPROM replacement MAY fix:
- On screen display is stuck on logo screen
- TV will not power on with remote or buttons (LED indicator remains same color)
- TV will not turn on after being off for 30+ minutes
- TV shuts off by itself during channel scan or when switching inputs
- TV turns on and is stuck in color test pattern mode forever
- TV turns on but there is no backlight (LED indicator shows TV is on but there is no image)
