Just in case any of you were following along at home---I replaced the Y Control board and everything works like clockwork!

Re: LG 50PT350 Help
I'm an electronics noob, so even if I was able to measure, I would doubt my own accuracy. What are the chances or what would be the signs that it was the Y-board?
best,

Re: LG 50PT350 Help
I really don't think it's the logic board since I just replaced that part and it's basically doing what it was doing before. Other thoughts on what it could be?Leave a comment:

Re: LG 50PT350 Help
OK--I know it's been months since I posted about this but I've been traveling and working on the TV as a side project. I replaced the logic board on the TV and I got excited--I turned it on and TV started playing---for about 5 minutes and then the screen went out again. I turned it off and turned it back on and I got a blank screen. I then turned the TV off for 1 minute, turned it back on and once again the TV worked for 5 minutes before the screen going blank (still audio from the station).
Please help!Leave a comment:

Re: LG 50PT350 Help
When the jumper cable is connected to the EXT_AUTO_GEN and to hole on the right of it and that cable is unplugged, I get a blue screen and it immediately shuts off. So, if that means I have a control board or power issue, is there a way I can tell which one? Would I be able to use my Multimeter on the power board to find the culprit or at least narrow it down?Leave a comment:

Re: LG 50PT350 Help
Is this the one you speak of? If yes, how do I connect them?
Thanks again for your help.Leave a comment:

Tom,
finally had a chance and got a new piece of wire and soldered it in a bit. Got something new this time. When I turned it on, the TV screen went all blue and then shut itself off after a few seconds.Leave a comment:

Tom,
I followed your instructions and got a blank screen. The backlights looked like they were on but nothing came on the screen. To very I did this correctly I included a photo.
Thanks!Leave a comment:

Tom,
I've attached a closer image of this board. Let me know if this will suffice
Thank you....Leave a comment:

Re: LG 50PT350 Help
Hi Tom,
I have not tried enabling the EXT AUTO GEN on the control board. How do I do that and what will it do?
Below are photos of the boards. Thank you in advance....Leave a comment:

LG 50PT350 Help
Really stumped on this one. When TV is turned on I get cable for about 3 seconds and then the screen goes black but audio continues. When I change to a different video source like HDMI 2, EXT, etc the menu comes up and even the screen saver comes on. I just can't get any picture on cable or even if I hook up a gaming console, that won't come on.
Took off the back, no blown capacitors or anything. I have a Multimeter at my office, just not at home, wanted to talk through the problem before I go looking for ohm readings.
any ideas what it could be? -
