LG 50PS30 Plasma Purple Pixels
Anyone offer any advice to solving this problem. 2017 we replaced a board based on advice here and got another 6 years out of this tv set.
It's really apparent in the white colors on the screen.
Here is a video

I tried to make adjustments to the VS adjust It did clear it up but it hit the voltage limit and reset the tv. There are no broken solder joints and nothing looks visibly bad.https://LG 50PS30 Plasma Purple Pixe...<br />
Anyone...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: LG 50PS30 Plasma TV No Picture, Sound Works.
Well my second TV 50ps30 popped last night, I have the back panel off and I don't see anything wrong. Made it a good 10 years march of 2019 manufacture we bought both at the same time.
I was watching youtube last night and noticed a bit of a blue light on the right hand side of the tv running the length of the screen it made a pop sound, I figured a capacitor blew. I don't see anything that indicates anything blown up. Now the tv powers on and the right hand side of the tv if you would divide it into vertical quarters...Last edited by AndrewC63; 12-08-2019, 12:44 PM.

I've done soldering of bad capacitors on a 28" computer monitor I was able to test and find which where bad but there are so many things on that board anything I can specifically check to see if it needs replacing before doing the complete board

The lucky thing is I have a second working tv identical I bought two of these back then, do you think it would be worth while to open both and swap that part or I am looking at having two broken tv's.
That's the board with the blinking light? I found one for 40 bucks maybe I'll just get it and swap it out.
Those voltage are way off what they are supposed to be, will an oscilloscope nail down whats wrong 100%?

Re: LG 50PS30 Plasma TV No Picture, Sound Works.
So I went thru the pages and tested some things found something interesting.
I can't test the wave length I don't have anything for that.
VS 1 195.5V
VS 2 195.5V
VA 1 65.1V
VA 2 65.1V
I did make adjustments very small but I'll have to correct VS closer to 195V
Next Set of measurements
+VY 14.00V
+VSC 14.88V
Waveform I skipped
+VZB 2.702V
Tell me what you think but those voltages are very...

LG 50PS30 Plasma TV No Picture, Sound Works.
Can anyone help me trouble shoot which board needs to be replaced in my plasma tv
I have already tested the main power feed line into the first board its getting the proper power.
I have checked the VS VA they have the correct 65V and 195V the other 5V is correct leaving the board. I don't know what to further check.
I have checked the fuses for continuity they have continuity.
I was checking some little blue disk like electronics most of them have continuity but one in the middle of them does not I don't know enough about electronics to know if that is...

Re: LG 50" Plasma 50PS30-UB powers on, no picture, no sound
I have the same problem LG50ps30 no picture sound remote etc work, checked the voltages VA VS they are all spot on. Did you end up getting it fixed? I notice that the chip in the middle of the board you said you replaced on mine is very hot almost cant touch it.
The two big boards with many large heat sinks are cold
