LG 55EC930V OLED - 3 Second Power No Display

[Dac12]

Earlier it was responding to the remote but I kept tampering with the microswitch and now its not responding. But everytime I press the microswitch the shading and the percentage of screen shaded changes.

I should have entered the code via a normal remote. But i dont really want to give up on this yet. Is there anyway of getting it back to the lockdown stage? I just disconnected the tcon ribbons and it went back to lockdown.

I've added two photos and the chip I assume below this ans the rubber is very hot to the touch, maybe a fault?

Sorry just realised the photo was missing.

unplug the EVSS 24V block from PSU side... and send In_Stop when TV go to STBY plug it out from wall for 10 minutes to discharge and put back EVSS socket then turn on
you can also run PSU and T-CON driver bords and OLED as standalone state... it could show you the effect if the OLED defekt

Thanks I did exactly as you said I unplugged the EVSS 24v and it went back into STBY. Sorry I'm a bit new to this, if I correctly understood the procedure. Turn the tv on , disconnect EVSS from psu side, keep pressing In_Stop until TV goes into STBY. Reconnect EVSS connector. Don't I then press the microswitches and try to input lg code as per other posts? (I've attached a photo of the display again, but I haven't done your procedure yet, the screens not cracked it just a shadow from furniture)

disconnect the EVSS, turn on the TV ( screen remain black ) ... send In_Stop -- followed with code via RC 0413 ... TV go to STBY.. leave it 10 minute to discharge ... EVSS socket back then Turn on-- do first install

Unfortunately no success , the relay keeps clicking every approx 2 to 3 seconds. After disconnecting evss as per photo and switching on the tv it just keeps clicking.

put back the EVSS, just disconnect the lower LVDS from MB side , check (screen will remain black )

Thanks tried that but just clicking every few seconds but the mb red led not lighting up. Either I'm missing a step or I've messed the sequence by messing around with the microswitches or the panel is beyond repair?

by disconnecting the lower LVDS we are here cuting the SOS signal from t-CON in case the panel have fault.... but yours look like now the MB .. or microswitches one of them keep in push position... you need to check

I've tried to attach your post but struggling to attach it

It is not the first nor the 100th but more of the LG cpu that can be soldering ruined...

Do you mean the lg cpu may require soldering?
Thankfully i got the normal remote working again but only the on and off function. The lg service remote works as well but when i press in_stop followed by 0413 and ok nothing happens.

Some times the tv does makes a whooshing laughing sound. I've connected an old ps3 console but no display change. I've tried a wireless mouse but no display change.

I assume in_stop isnt working because the tv isn't going into standby. I've seen a video where pressing the menu button over 10 times is the same as in_stop and then they enter 9876 and then 0413 and again 0413.(?).

any suggestions would be appreciated? Thanks
