The problem surfaced again and capacitor trick did not work again on any of the voltages.

I don't have any freeze spray or compressed air on hand but I will obtain some. What is the purpose of freezing the chip? Should I expect to see a hotspot where there is a bad solder connection?

Another observation is that various settings have changed between power cycles (audio settings, wifi enabled and home/store mode) so maybe there is some failing eeprom?

The problem seemingly fixed itself for a few weeks (~10 hours of watch time) and has now appeared again. Disconnecting the left most quarter of the screen DOES NOT fix the issue anymore. I can't find any permutation of disconnecting ribbon cables that fixes the problem and even when a section of the panel is disconnect that portion is still washed out white.

Thanks for all the suggestions. The results I have are:[LIST][*]The TV was off for a few weeks and upon powering on the colors remained correct for ~2 minutes before switching to inverted. Other than that initial power on, the color now inverts almost immediately upon booting up from powered-off (and from standby).[*]Checking grounding tape - the tape on the far left (on the quarter that causes the color inversion) was semi-peeled off although I think still in contact. I applied clear tape to firmly affix but that didn't change anything (I am reusing the grounding tape). After seeing this I am...

Background:[LIST][*]Hisense 65H6570G stopped working and I root caused to a burnt out LED in the backlight. (For anyone interested the power light pattern when the backlight has gone is 1) two long flashes, 2) a very short third flash, then 3) back to solid red ) [ATTACH=JSON]{"alt":"Click image for larger version Name:\t20240916_202822.jpg Views:\t0 Size:\t2.72 MB ID:\t3486172","data-align":"none","data-attachmentid":"3486172","data-size":"custom","height":"400","title":"burnt...
