Try to reflow the main processor on the main board may help.

I did just that to a 42lw5700. It is working again for now. It would switch on but the back light wouldn't light up. No sound also.Originally posted by Sevenqi View Post

Re: LG 55LW5700 Service Manual
Hi all,
Bringing up an old topic. I ended up reflowing the main chip on the main board. With success. It lasted for a while and died again. I reflowed it again and it worked.
The problem I'm having now is that FTA is not working. Which is weird since I never touched it. I had a look at the service manual and there's a listed procedure to check to see if there's power to tuner. But the problem is that since my version is a TA not a UE (service manual version) the test point dosent exist on my board.
- check tuner 5v power L2104, 2101.
These values don't exist on this board. Only 2204 and 2201. But I can't find them. Could they be behind the cover on the tuner itself?
It would be good to get it working again. Any ideas?
Cheers.Comment
