Dear Chaplink,

You said "two dark smudges on monitor screen".

Asumming that these smudges are digital and not just something tata you can remove with cleaner, If your moniter is back-projecting then the issue is probably that the projector has been damaged.

If your monitor is a flat-screen then the gels inside of it are misplaced from somone touching and damaging your screen.

So basically, the only practical thing you can do is buy a new monitor.

LCT TV picture blurry with black smudges until it warms up

No easy way short of monitoring with a scope and or voltmeter, based on age of set I would first "look" at all the filter caps in the main power supply--bad ones when they get hot can regain some function:

?Smudge on lens maybe? Shows up in pictures.

Hi!
Does the smudge changes / mooves as you zoom the lens? If so, the smudge is most likely on the focus lens, if not, there's something on the CCD. In both cases the lens will have to be taken apart and cleaned by a professional. I suggest you contact a local repair shop and see how much they ask for it.
