I picked up a used Micron AP150T at our town's recycling center. It
cost
me nothing, so there is no loss if I can't figure out what's wrong.

When I hook it up to a computer, all works just fine. Then the picture
starts tearing horizontally after a few moments of on time. When I hit
the Function key, the function block pops up and looks perfectly fine
while the picture behind it is tearing.

So I assume that the sync signal from the computer is somehow being
lost. It does the same with two different computers, so the computer
output is not the problem; the computer outputs are fine with other
monitors.

Any ideas? Is there a know problem with this unit syncing to the VGA
signal?

Bad electrolytic capacitors are fairly common and can cause any number
of strange symptoms. That's where I'd look first, the surface mount sort
used in flat panels tend to be especially troublesome.


I second this. About 90% of the bad LCD monitors I see can be fixed
with new caps. Don't forget about the surface mount electrolytics on
the main board. I just fixed a Viewsonic that needed to have every
single cap on the main board replaced. Andy Cuffe



The display generated internally is just fine. Only the externally input
display tears. So it can't be "every single cap." I imagine it is
something in the sync input. I'll be checking it out. And like I said, it
is a "saved" monitor. If a quick fix won't do it, back to the dump.
