Question about Televison & Video

1 Answer

My tv started to get Purple thick lines accrossed it, until finally it went black. After it has been turned on for 15 minutes the screen will be visable, although it is VERY dark.

I have taken the back off the TV and all the components are exposed, with what appears to be part numbers/bar codes. if you have ANY idea of what went bad, I would be greatful as the TV is ONLY 3 years old.

If it's a plasma I would say you have a bad y sustain module and y buffer. Check the buffers and y sustain.

Try a reset but unfortunately I believe it is a board cratered by the power outage. Try to get things shut down when the power goes

When turning on the TV, it has redish, purple & green lines across the screen & you have to leave it on like that for at least 5 to 10 minutes for it to warm up. You just have to keep turning it...


Hello,

Al Plasma and Lcd TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em. Good luck.

Purple Screen


If it is only 2 months old,then you still have warranty.
A purple lcd, viewfinder and photo is a 100% CCD failure.
If out of warranty, not worth the repair.

No Blue. Horizontal Lines.


Not to me, but it also depends on if you could do this yourself or not. And the area you are in sometimes is responsible for the cost being high.
