I have an old Sony LCD SDM-S81 that worked fine for me for a couple weeks after
I got it used. Today, I found it displaying pictures badly, distorting the
colors by seemingly greatly exagerating the intensity of colors in areas with
changing shades of colors (Photos and Video, mostly). Additionally, the colors
seem to flicker, as if the problem alternates at a high rate.

Can anyone give me any advance clues as to what to look for when I open it up?

It is the monitor. Plugging in my old CRT shows no suck problem.

Thanks.

Sell it to a dance/night club ?

Looks like an intermittant problem. Today it's working.

Bad solder joint?

That would certainly be the first thing to check.

Is the problem on all colors, or just one?

First thing I saw was orange areas around faces, but also distortion on blue
areas, like a picture of an alpine lake. So probably all colors.

Do you mean there's smearing or "blooming"?

I don't know the proper term I guess.

On faces, there were irregular bright orange areas on faces, mostly near the
edges.

The lake picture had bright blue areas scattered of the darker blue surface,
along with exagerated colors on some of the surrounding mountains and
vegetation.

It showed things OK as far as I could tell on windows like outlook express where
colors were solid with sharp edges. Other windows with "solid" colors that fade
slightly from one shade to another would have exagerated colors in parts of
those shaded areas.

I tried taking some pictures. I'll see if I can find a place to post them.

And now it's not working right. It seems to flip-flop maybe once a day.

FWIW. I finally got around to opening the monitor. I unplugged and replugged the
internal connectors, and tried it again. It seems, so far, to be working fine
now. Maybe I got lucky.

Obviously, the problem was caused by oxidized connections. Did you use a
cleaning agent, such as DeOxit, before reattaching the connectors? This
might keep the problem from recurring.

I didn't, but will if the problem re-occurs. Thanks.
