Re: 47LW6500 Debug Help - Power Board or Mainboard?

The MICOM is not sending the control signal for this section of the circuit beside the DRV circuit.

Thank you for confirming this. I was searching online for a replacement board, but was not able to find any... so I think my options are either baking it or trying a mail in board repair service. Has anyone used one of these services or know a trusted one?

One there, 72 bucks seems a little high to me? BUT they don't seem to be readily available so might be the best bet:https://www.tvpartstoday.com/EBT6139...bt61399411.htm

Does not seem to be quite exact the one I have:

EAX63969204(0) vs EAX63969205(0)
EBR73358205 vs EBR74235304

Guess that's a good question, I matched it up by part number LG EBT61399411.

How did you figure out if it was a match or not? Just in case others show up I'll know how to check if they can be compatible even if having different numbers...

Key is to match your service code on the back cover of the tv, it is 47LW6500-UA.AUSYLUR correct?

Yes, the service code on the back cover is 47LW6500-UA.AUSYLUR as well as on a sticker on the main board that includes the different number EBR74235304.
