LG 60PC1D One small vertical line about a pixel wide.

This is my personal tv, that I have had for about a year.. Anyway lately it has developed one very small vertical line about a pixel wide, but it only runs half of the screen. Is this a driver board starting to fail?

It's probably a defective plasma panel.

Damnit, I was hoping you werent gonna say that. I love this tv. Wouldn't it run the lenght of the tv though?

Depends if it's a dual scan panel. If it's dual scan the panel is probably the fault. If not then there's the very rare possibility it's the digital / control board. I'd say dual scan is unusual for a 720p, but I'm not sure without a picture of the chassis which I can't find on the internet.

Its doing is sporadically, its on the screen for about 15-20 minutes then disappears completly.

If it's sporadic, there's the chance it's a loose connector.

Those older models used address boards on top and bottom. Try reseating the ribbon cables on the address board. Usually one pixel lines are a defective panel (TCP IC).

Yeah, top/bottom boards = dual scan panel. More expensive (TCP cost), but makes the Y-buffers, Y-sustain and Z-sustain cheaper.
