NEC plasma TV: what's the cause of image "solarizing"?

Is this same problem present on all input signals? Is the photo you posted taken from a DVD, a live cable or satellite signal etc?

The panel is getting old. Possibly a Vs adjustment would fix it, at least temporarily.

That isn't solarization. It's more like posterization.

It looks, in part, as if the display cannot create sufficiently small brightness steps to render fine shadings. By modern standards, 8-bits per color would be considered rather skimpy.

My gut feeling, though, is that the set is defective, most likely whatever chip or board does the D-to-A conversion.

electronic component?

This is a power supply voltage adjustment?

Could this be a power supply problem?

Not sure if it's the PS, but if that's how it looks with different sources, it definitely needs repair.

I didn't read the original post. What is the history, be brief.

It's 8 years old. Splurge for a new TV already.

I have a 50-inch Pioneer. It is beautiful.

Ignoramuses making statements like "spend the money, already" just show their immaturity.

There are many reasons for resurrecting an old display: as a hobby; to keep it out of the landfill; to give to an older friend who can't afford one; just to mention a few.

Although it's first on your lips, 'cheapskate" is not always the reason...

To summarize: I just received this monitor, so I don't know its distant history, but...

The image will "solarize", it seems to be compressed in a small range of contrast. See this image:

Note the blue and red outlines of the highlights (cheekbones & noses). These highlights seem to "sparkle". (The horiz & vert lines are just moire effect with the camera; ignore these.)

Then this morning when I turned it on, I got these images:
