Dell M992 19" CRT (18" Viewable Help)

[noobtech]

Hi guys, I used to own a couple of these monitors and sold them last year to get The LCD's, which are great! But I saw some for sale in the local ad for $20... (A business who upgraded to LCD's as well).... so yeah, I got it and it's kind of blurry looking... not what I remembered them to be, so I saw some threads saying you can adjust the pots in the back, but are very dangerous... (scary!)

Do all CRT's have those adjusting things for the focus in the back? Do you guys think it's safe to just unplug the monitor and hit the power button a few times to discharge? I will try to stay clear of anything but those adjustment knobs...

I'll take some pics... Any advice?

Not all CRT's have them. Pressing the power button a few times will not make you safe. You should probably buy a plastic screwdriver.

after reading about the fw900, I built up enough courage to take it apart after seeing someones diagram...

I took out all the screws, popped off the plastic cover, removed the aluminum shield and found the adjustment controls on the back left corner. One does the brightness, and the other two does horizontal and vertical adjustments..

While I had it open, I got some of that canned air and sprayed out some dust while I was at it...

.....I think i was supposed to adjust it after it warmed up a bit? It looks blurry again.
