3.3V will generate one time only it used also by TV RC of the wifi / BT module... as well the IR so any one have short will kill this rail

When I press on on the RC STBY goes out and returns directly in the same position as if it can't start the TV so the RC works.
I have managed to get rid of the black heatsink.
thanks for the chart but it's not exactly the same because on my kontact pin 6,16,19 and 20 are free(not used) plus I only have a start button

[Diah]

if it response to RC then try my post 54 56 ..... and check the LVDS socket which pin have 3.3V

You can activate pmic voltages shorting trdy1&3 test points, for this test you must disconnect lvds cable.

There is nothing complicated here, they are here, install a jumper between them and disconnect the U-shaped cables on the panel strips one by one...

[bohaboha]

No Diah nothing displayed. yes am asking because none of the code is working it seems the TV freeze on STBY
however the 12v,3.3v and 5 volt are present on the Tcon part of the board and that 5v you wanted on pin 7 is there on pin 12 instead of pin 7 but no 3.v on the lvds
i do not understand why there is 180v and 190v on the cold side of the power supply
