Re: Help with 26LG30-UA
Well, in a desperate attempt to avoid a reflow, I replaced the t-con. Sure enough, the unit starts right up!
Thank you everyone for your help!!!

Thanks! I'll pick up a cheap heat gun and try reflowing...Leave a comment:

Re: Help with 26LG30-UA
Interesting thought. I haven't tried just letting it sit on for a while.
I'm all for reflowing the boards even just as a "what the hell" possibility.
In this case, which one is the "main" board you refer to? Is that the power supply? The t-con? The one with the tuner and video inputs? or the one which i'm speculating has to do with power inversion for the display?Leave a comment:

Ok, so if the t-con looks ok, what's the next logical thing to look atLeave a comment:

Re: Help with 26LG30-UA
How do those voltages look? Anything off? Is that polarity change a red flag or is that normal?
Thanks!Leave a comment:

Nope. I'm the sole owner and done the only work on it which to date consists only of swapping caps on the power supply.Leave a comment:

Re: Help with 26LG30-UA
Thanks so much for your response!
Requested picture is below.
As for caps, I bought a rebuild kit from lcdalternatives.com which is actually how I discovered this site. I don't honestly know what low ESR caps are, so I'm not sure if that's what he sells or not. Would they be marked in such a way to identify them as such?
Can you help me identify which is the T-CON board so I can check those voltages?
Thanks again!!
PS - Disregard the detached transformer, it's an older pic, I've already corrected...Last edited by ragingfish; 01-18-2013, 08:24 PM.Leave a comment:

Help with 26LG30-UA
Hi everyone -
I've been searching everywhere trying to figure out how to diagnose this TV, but have come up empty. I'm hoping someone here can help!
I have a 26LG30-UA that's giving me problems...again. The first issue I had was about 2 years ago and I replaced some bad caps on the power supply and all was well.
The new issue is more than just bad caps. There WERE bad caps, and I replaced them, but continue to have issues. In addition, I sourced out another power supply, just in case, but that is not the solution.
I've read online that...
