LG 55EC930V OLED - 3 Second Power No Display

[Dac12]

Please ignore this photo completely wrong ic sorry

[lotas]

Thank you where would we find this ic3000 ? Would it be on the MB? Secondly if pin 6 is disconnected will the seevice remote work? We checked mainboard but we can't see this ic3000?

Here is micom ic3000, but the remote control will not work if you cut the track to the 6 pin

[Dac12]

IN_STOP will not work, because the IR sensor of the remote control is connected to pin 6, i.e. the TV will not receive signals from the remote control.

Ignore this is wrong chip

Found it , I think please see attached photos- but how would this be disconnected? Sorry I'm new to this

We've found pin 6 but how do we disconnect this? Which one route no 6?

don't miss up with SoC soldering.. .. i wrote MB, not SoC... yours MiCOM firmware distributed because of playing with microswitch which had nothings to do.... try disconnect pin 6 of MICOM and try IN_STOP

I mean CPU can easily be the problem, stop

[Dac12]

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

But i do not see a chip or rubber, only a screen...

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

[Dac12]

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

Will do thanks

[Dac12]

Sorry fourth attempt at trying to upload the photo. Sometimes it get hot to the touch.

[Davi.p]

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

But i do not see a chip or rubber, only a screen...

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?

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

[Dac12]

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.

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)
