LG 55LW6500 Main board faulty Can't Post

Hello Everyone,
I have a LG 55LW6500 TV and it stopped working suddenly. I had it connected to a computer via HDMI and I was watching a video on YouTube. All of a sudden TV turned off and then it came back on (just the front LED indicator light) but no picture, no sound and no backlights.

So far, I have checked the power supply voltages and they are correct. I checked the LED backlights by jumping the connectors on power supply board and they are good. Now I think the main board is faulty. Unfortunately LG is not making EBT61555001 main board anymore and I am unable to find it anywhere (not even used one).

Is there any other main board which I can use to get this TV running again?

All I want is TV to turn on and connect my computer via HDMI I don't care about smart functions or audio

Thanks

Shop Jimmy shows three different Main boards used in that model:
EBT61394305 55LW6500-UA.AUSYLHR
EBT61805205 55LW6500-UA.ACCYLHR
EBT61805211 55LW6500-UA.AUSYLUR

They DO NOT show a EBT61555001 at their site.

For anyone who gets into the situation like me, I have found the substitute for the original mainboard.
LG makes a repair package for LG 55LW6500 TVs which includes a mainboard, a small remote PCB, a magic remote and a regular remote. The part number for this assembly is AGF78482709
I ordered this today and hope to get it in next 7-10 working days.
I will update after installing it.

Hi I got it from www.statewideapp.com.au in Adelaide Australia. believe it or not it cost me $248 only and It worked!!!!.

One thing I would like to mention is I lost one HDMI port so now I have 3 instead of 4 but that does not matter because I use only one and there is no VGA port in this one as well.

Mannoye

I also have the same tv and it had a similar issue, I had power down the bottom on the light but not screen or sound so I ordered the same replacement kit from statewide apps

https://www.statewideapp.com.au/lg-package-assy-253711

The good news, i replaced the board and the tv is working fine !!

but i have one power cable not plugged in and what i think is the WiFi doogle left over that I wasn't confident on where it attaches to.

here is the old board https://pasteboard.co/JDN5Wb6.jpg
here is a picture of the new board https://pasteboard.co/JDN7xi1.jpg

i have a spare cable at the top as the boards were different so there is no plug at the top of the new one, and it doesnt reach to the bottom plug on the new one, so i tried it with it left off. which it works but unsure what to do with it ???

the dongle ?? https://pasteboard.co/JDN8o9F.jpg

does it go into that bottom spare port with the newly supplied cable ??

The end result is the TV is working, i just need to tidy up a few loose ends and ensure i have installed it correctly thanks
