Westinghouse VR-4085DF Restarting Issue

[bball1911]

I am hoping to repair a Westinghouse VR-4085DF LCD TV. When watching the TV lines come display across the screen followed by the TV power cycling itself. It started about a month ago and would happen maybe every 5 minutes. Not it is to the point where it happens within a minute. After a few times the TV doesn't turn itself back on. I can manually turn it back on but it does do it on its own. The TV works great when it is not turning itself off.

I unplugged the t-con board and it still restarts so I do not think it is that. All inputs work also. I also removed the power supply board and inspected it for any bulging capacitors or burns and did not see any but I have not tested it with a multi-meter. I have or can get most tools that are needed to test any other components. If anyone has any suggestions or advice any help or direction would be greatly appreciated.

I have attached a picture of the display prior to it restarting as well as a picture of the boards on the back of the TV. The display lines are mild on the picture compared to how many lines display sometimes. There are times where you cannot even see the display there are so many lines. If anyone needs any additional pictures or information please let me know. Thank you for taking the time to read the post and in advance for any assistance you can provide.

I just wanted to post a follow up. The TV is still having the same issues after making sure all connections were secure as well as leaving it unplugged for several days allowing the capacitors to drain. Any new ideas on how to repair this would be great.

You need ESR meter to test the caps. Did you inspect the caps on the inverter board?
We also need better pictures of the board, please upload good clear whole pictures of the power supply board, the main board, inverter board.
You need to look at the power supply board connectors to see if the pins of the connectors are labeled to tell us what each pins are for or not because you will need to check the DCV on the pins.

I have loaded clearer pictures. If anyone wants the original of any let me know. You can zoom in and read almost all of the information on the boards in the original, I am not sure the same clarity will be there once posted. Please let me know what you would like me to try next and I will post results.

I have visually inspected the boards and caps and do not see any signs of malfunction but I am also a novice at this and may be missing something. I am have loaded pictures of both boards that I see. I think the power supply and the inverter board are together on this tv, if not hopefully someone can direct me to the board I am missing. Hopefully the pictures posted are clear enough to see the details on the pins. If not I will take a look and gather any information required.
