If TV is upright TV runs for 14 minutes then turns off. At this point it tries to come back on every 5 seconds. At the 1 minute mark it came on for 14 minutes again and keeps repeating this process. When I place the TV face down with the back removed it runs fine. I've had the TV on this way for over 2 hours with no power cycling. Both the power supply and main board have been replaced. Any help please.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Try tapping on the boards with wooden stick or plastic stick while TV is facing down, also try moving the cables around to see what happen. Also did you try post #2?Last edited by budm; 06-30-2020, 03:19 PM.Never stop learning

LOL, baking the powerboard would be a first that I've heard of, they bake mainboards to reconnect solder of bga chips but don't always work or last very long, that's IF the board keeps overheating, some have used a fan solution after baking with a lot of success.Last edited by nomoresonys; 06-30-2020, 04:08 PM.

With the screen face down turn it on with mainboard unscrewed in upright pos. then bent it gently, if it stop working a reballing is needed, if its not the mainboard try the PSU. using gloves or better a wood spoon.Last edited by Davi.p; 07-02-2020, 05:08 PM.
