It's all of that radiation. You'd better invest in a Geiger counter.

Very Funny! Sounds strange but it has me concerned that something might be smoking & it's not me!

Is it warm anywhere? Where exactly on the monitor is the 'blackness'?

>Very Funny!
I'm serious. Radiation and heat will discolor plastic over time. Check for hotspots on the case, odd happenings on the screen around the edges, and make sure that everything is kosher with the power coming in (not too much). If you see anything out of the ordinary besides discoloration, pretty much all you can do is replace the hardware. If you don't see anything else, I wouldn't worry about it.

Indeed. This sounds more heat related than rad related tho - plus, if it was leaking rads, he'd feel the effects from it pretty quickly... remember the days of un-sheilded monitors and headaches after an hour? =P

The only warm spots I feel is the cable modem sitting next to the monitor & the side next to the monitor is black also but think it's always been warm as I have it on all day. The monitor is less than a year old. How would I know if I got too much power coming in? We had a power outage for 4 days last week. Could a power surge when the electricity came back on cause it maybe?

The blackness is all over the monitor but mostly the front. I have had some headaches recently which is unusual for me but figured from staring at the screen too long.

<1 year old means get it the hell back to whence it came and get a new one... that is a hairline in the shielding. I'd also stop using the monitor asap.

I agree with all of the above.

It is a health hazard and the monitors use should be immediately discontinued and a new one purchased (or as someone stated, under warranty monitors should be replaced for new ones...).

Be careful in the transport of the monitor to the box and make sure it doesn't crash around a lot. I know this sounds stupid, but taking some extra care around CRT never hurt anyone.

Good luck
