Re: [sprinklerman] LG led with black screen

Firstly, I'm not an expert in TV repairs but, I have a lot of experience in other spheres to do with communications. There is wealth of information at your finger-tips nowadays on the I-Net.
I personally would not buy anything at the stage you're at until you've established what was causing the issue i.e. black screen. It might well have been the T-Con board but, you need to establish that with the 'Flashlight test' -see 'ShopJimmy' YouTube post-.
Now you're in a situation whereby the old T-Con, and the new for that matter, needs to be tested in the TV to see they produce an image on your black screen. If the old one is okay fine.. test the new one too.. if that's fine you could always sell it and recoup some cash to finance the real issue?
Have a look at the 'Youtube' posts -below- (there's lots more but, for my issues -similar to yours- I found them amongst the best; the technician's in them have different methods but are sound -IMHO-). I would do this research even before touching the TV.. you may need to buy/borrow/beg some test-meters.. In any event (and above all).. you need to adhere to health and safety. I apologise if I appear to be preaching but I hold your best interests at heart.
I think it's worth persevering with.. you may end up with your TV back and not in the dumpster...
Hope this helps.. good luck.
