Re: lg 42pc1da sound but no picture

Just tested vs and va from psu, it is 186.6 and 59.8 respectively. I'm sorry but I have no idea how to test vzbias, and all the screen does is occasionally white spots when in a dark room, no picture at all

Re: lg 42pc1da sound but no picture

I'll have to start testing the voltages more, but the old y sustain shorts between the vs out and some pins so I at least know that was for sure bad.
Thank you for your help so far.

Re: lg 42pc1da sound but no picture

Thank you for the response, I just tested the ipm on the old y board, it was toast. He new one however is fine, could the x board be gone again too? What else would cause no picture but maintain sound? I was under he impression it was a y sustain issue

Edit: I'm sorry, I keep saying x sustain for some reason, I mean z.

Hi all, new here but I have a 42" LG plasma that I got for nothing, it made a loud pop and he picture went on it. I did some troubleshooting but nothing too crazy because I have limited electronics repair experience. The y-sustain had a blown fuse and cold heat sinks after leaving it on for 20 minutes. So, I replaced the y sustain and buffer but it is still the same. The x sustain was replaced in 2010 and the tv hasn't been used since it broke in 2011 so I don't think that's the issue. All fuses are still good, I checked those, but the board on the center back has a few green leds and one...
