This tv once turned on , makes a 1 click then another click comes on for 6 to 10 seconds shows image and sounds then shuts off. Then clicks again and shuts of in 3 sec with no image or sounds. Keeps doing this. I Did the self test with the logic board and the main board unhooked. It shows all the colors and pattern test fine. Never shuts off. So i order a main board.

Second main board installed and it did same thing. Made one click then few seconds another click. Tv comes on with sound and video then shuts down and does the 3 sec click on and off thing.

I'm guessing bad main boards. Just figured i would ask for some input before ordering another board.

Self Test i did https://www.youtube.com/watch?v=IXXSdctd7Y8

Follow up. Still having issues. i have replace 3 main boards. 2 was bad.
This last main board. work good for like 1 min to 2 min. Then click out and came on again.
Then just keep clicking on and off. Anyone have any suggestion. Thanks

By doing the Self test above. It has to be mainboard right.

Just a follow up. Tv is working now. The only thing Self test shows is panel okay with images and stuff. Does not show if you have a problem with power board completely.

Had to change 5 caps on power board and one on X board.
