Expert:  Mike G. replied 1 year ago.
I understand your current symptoms. I am asking if the symptoms changed after replacing either of the boards? In other words- did you have these EXACT symptoms BEFORE you replaced either of these boards?
And-
I want to make sure when you say Power board, you are referring to the board that the AC POWER cord plugs into?
And-
I want to make sure when you say Main board, you are referring to the board that has the Audio/Video input jacks?

Expert:  Mike G. replied 1 year ago.
I'm not sure you are reading my entire reply. So let's try again...
1. What exactly were the ORIGINAL symptoms?
2. When you changed the power board did any of those symptoms change?
3. When you changed the main board did any of those symptoms change?

All of this information points to a defective Tcon board. Part number is ***** Kinda hard to find a expensive. Here are links to two places to buy the board:
