LG 60PX950-AA Repair. Have test pattern.

[guitargeek89]

Hi,

First post, so Hi All.

I've just bought an LG 60PX950-AA that needs repair, And hope to replace my TV it.

It powers on, Has sound.

When I jumper the test points on the (T-CON?) Board, I get my test patterns, Albeit after a few rounds i got a solid single pixel (dark) vertical line during red and blue not during white or any other test, and a single off colour pixel during red and blue. <hoping this will go away with fault or point to it.....

Not sure which board I am to blame, Is it more likely to be the tuner board? > remote works fine, volume up and down, and channels.

Or is it going to be something else???

In my industry, we fix a lot of lcds, psu, and crt.. but never Plasma... Really appreciate any help.

Cheers Guys!

Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

The trouble is with any vertical line on a plasma can be signs of a failing panel can you upload a picture of the screen showing the line?

Thanks,

I'm hoping its not the panel. I'll upload a photo this afternoon, It actually appeared while I was watching it cycle through the test patterns. Was perfect for the first 2 passes, then it appeared.

Sorry for the quality of the photos. new phones in the post!

As you can see, the line is there in blue and green only, white and red it is not apparent.

The other vertical lines - faint discoloured lines, are from the camera, they're not visable to the naked eye.

anybody able to shed some light on this for me? should I go ahead and order parts to repair, or is panel likely unsalvageable

I'm thinking you have a panel fault and since you're looking at a mainboard replacement which I would expect to be expensive the question is if the line is still there can you live with it or Not? Will it continue to get worse?

Only ever had that once on a panasonic and depending on the scenes and colours it was sometimes not too noticeable. Generally it's the IC embedded on the tape package to the panel so not repairable.
