Set up a flatscreen for a friend... Problems!

Videos to fix dead or stuck pixels. In this case, entire colums of the matrix aren't working.

This...usually...is caused by a bad panel...specifically the connections to the panel itself.

But what I find odd is that you said every other column. Usually this kind of defect will manifest itself as multiple columns next to each other...not every other one.

If you thump the screen gentely, if it is a bad connection, you may see those columns flash or change color. At this point though, it almost sounds like a problem with the panel driver itself.

the point is, this is beyond what you can really do. It needs professional service.

I have not seen the "guts" of one of these sets yet...how is the connection usually made to the panel? Perhaps some sort of heat sealed "flex" cable?

It would seem that out of thousands of connections that must be made, this would be a likely failure point in the design.
