Please someone tell me that this TV is not scrap.
Picture works great but turns off after a few seconds. Backlight stays on, sound stays on.
Replaced T-con, same problem. Apparently TCON shuts down it's output due to overcurrent/fault detection.
Removed front bezel to get access to the tab bonds / COFs. Sure enough, to the right there are two, the first and third from the bottom that heat between 50 deg C and up to 100 deg C within a matter of seconds. All the bottom COF stay at about 40 deg C, all COF on the left side stay at about 25 deg C.
The voltage on the little ceramic cap right next to the overheating COF is 5.9V.
Did anybody have this problem and find a solution or remedy? Maybe lowering some voltage that comes from the TCON/modify the circuit ect?
Why does it have an awesome picture while it's working? Why does it not always overheat to the same temperature?
I know chances a very slim to repair this but it's really a shame to scrap that TV.
