DS5102C, color LCD scope. When turned on, the leftmost quarter has
vertical stripes, the affected column is dead.

It looks like specific sub-pixels are not responding. R in one row is
dead, then G a few rows down, then B, repeat 10 times.

Thing is, after a few hour warm up, it works normally.

What is the most likely suspect before I go in and strip it down? Is
it likely to be simply a bad harness somewhere that needs reseating?
Or do I need to take apart the panel and fiddle arround with something
more arcane?

I don't think there's zebra strips in these things these days.


I would get inside and lightly probe with fingers, either final bond to the
LCD failed somewhere or solder problem on a demultiplexer chip. If bond
failure , do not try debonding and rebonding . That plastic reticulated
foam, pan scourer, pressed against the suspect area and padded/braced
against something is about all you can expect to remedy, unlikely to be
zebra strip.
