This low voltage could be a bad secondary cap or one of the small startup caps in the primary

Unless it comes out cold in the can.

Plot twist..the freeze sprays cost as much as a new eeprom lol
If i was to try heating it again. How hot would you guys go? Mine goes up to 500.Last edited by Demonata08; 05-18-2019, 11:17 PM.

It certainly could be the eeprom, I have had luck with freezing the eeprom ic. But you need to unplug the tv, then freeze the eeprom, plug in the tv and try turing it on. The eeprom is read at plugin, after its pluged in heating or freezing usually has no effect

Thats better, Ok so it is the whole tv that won't turn on. Can you post a clear picture of the back of the power supply board, If that standby voltage is only 3 volts and it should be 5 volts that would cause the problem.Last edited by R_J; 05-18-2019, 10:45 PM.

And the TV shows no signs of life when you try to turn it on. It has a red standby light that doesn't blink or change when you hit the on buttonLast edited by Demonata08; 05-18-2019, 10:40 PM.

I see your 5VSB is only 3 volts, that should be 5 volts I believe but could be wrong
Also can you attach the pictures to the thread

Originally posted by R_J View PostSo when you try to turn on the tv, and it does NOT turn on you have +13 volts ?
There are a couple other voltages like the standby AL+3.3V
and P-ON+21V
I believe the 12 volts is actually AMP+13V
Is this a BA3AU0F0102 3 power supply board?
I could be way off base here but isnt it not normal to have all the voltages on in standby mode?
Edit also my p on is 5 v not 21!?
