50" LG plasma . Vertical lines up and down screen.

I need help, I have sound but no picture. The vertical line are different colors and range in size. I have tried un-plugging, and check all hdmi hookups. I pulled the back panel off but i dont know what i am looking for.

Without a picture, it's hard to judge. However, it is possible the panel is bad, which would be uneconomical to fix.

YSUS panel? Could it be a fuse ?

I have a Thomas blasters multimeter 109, is there any way to check?

Re: 50" LG plasma . Vertical lines up and down screen.

Plasma panel itself.
Y-sus and Z-sus can never cause vertical lines.
They are only responsible for making the whole screen light up.

Please, we need pictures.

Do those lines move across the display occasionally?
How's it look like with a menu or video on the screen at the same time?

Possibly Y buffers.

Re: 50" LG plasma . Vertical lines up and down screen.

The lines do change, when i change chanels of push menu.

Re: 50" LG plasma . Vertical lines up and down screen.

would this also cause the tv to turn off?

[tom66]

Re: 50" LG plasma . Vertical lines up and down screen.

Y-buffers then.
I may have to retract Y-sus as "not being the cause"!
There is the possibility the Y-sus has damaged the buffer board.

Because of the cost of Y-sus and buffers it would most likely boil down to an IPM replacement plus replacement of up to 8 buffer ICs, which is not an easy job.

where is the best place to order parts?

[tom66]

Re: 50" LG plasma . Vertical lines up and down screen.

ShopJimmy, eBay, etc.
Be weary of eye-watering prices.
