Re: LG 50PG20D No picture but has sound, almost fixed but one last question
Cool, I guess if I find a service manual it will tell me the volts and the frequency im looking for. I will find out the specs of the scope my boss has and give it a look. Thanks again

Re: LG 50PG20D No picture but has sound, almost fixed but one last question
My Y sus has a spot that looks like another connector for the power supply should be mounted there right beside the actual power connector, I tested continuity between the connector and the blank and they are connected in parallel so when the tv is on vs is 194 and va is 60 as per specs on the panel, 5v is also good. I didnt plug the z sus back in as i have removed the components but tested the pins and all are good.

I did test the power supply Vs and Va and they where at 60v and 194v but that was on the power supply side of things, I will test and see it its getting to the sus boards, thanks for the advice its been great!!

yeah sure do, If it helps to know I have a little knowledge with electronics at the circuit board level also, I can diagnose faulty transistors and a few other components. I also repair pinball machines for a bit of fun, there a better mix of electronic and mechanics though

yeah nothing at all, I had the power off while connecting and dis connecting, im scare of the voltage that lives in there
The fisrt 2 times I turned it off and on after it died and before I pulled it apart there was a slight glow for a second or so when it was turned back on. Im thinking all boards may be bad or even the panel may have died.

LG 50PG20D No picture but has sound, almost fixed but one last question
Hi all, I have one last question on the repair of my TV but first a little about what I have done.
My Plasma tv was working fine and is only 3 years old and a couple of nights ago the screen went blank but the sound remained, it took my 20 seconds to realize that it wasnt good, remote worked just a black screen and completely black.
I pulled the back of and started to look for obvious problems, I couldn't find or see any so I tested the power supply voltage and all good, all fuses when good, no loose connectors or anything so I did some net surfing and reading here. After that I...
