Re: LG 46LD550-ub White Screen & No Sound

Just wanted to update. I got my multimeter and TCON. Readings at the PSU and Main board were good. I even got readings off the TCON but I wasn't exactly sure how to gauge those... however I replaced the TCON and that resolved my issue.

Thanks everyone!

So just an update. Multimeter will be here Tuesday. TCON Monday...

I was actually going to attempt to do this with the laptop. However, that resulted in the laptop detecting the TV and it continually sourcing back and forth from LCD and LCD+HDMI. The laptop sourcing that is. I suppose that could be a driver issue... I'll try again with the roku or some thing.

Also, on my Samsung it takes like 3-5 seconds to boot up. Likely because the caps I got were from radio shack and a little bigger than oem. At least it boots though!...

Thanks for the reply. Nope, no images. There is a faint line right down the center. I'll have multimeter to test a bit more tomorrow.

I know there have been a couple of these. I'm not the best tech, as someone said I'm more of a youtube-repairman ;p

However, I picked this TV up that was going to be recycled. I've repaired a PSU on a Samsung a couple of times by soldering some new caps to replace some blown ones. However, I'm trying to boil down to what component maybe the issue. Initially after some google searching I thought it maybe the TCON. I picked one up on ebay and it's on it's way. However I did a little more troubleshooting...

I plugged my laptop and an ethernet cable into the eth jack....

Guessing since it's been a few months, there was no resolution to this. However I am having more or less the same problem, will probably start another thread...
