\015 I have an Hitachi 19" monitor that has served me well since 1998. But lately, after I'm using my PC for several hours, it will make a slight noise after after which the screen will start shrinking for a second or two, and then it pops back to normal. Though I've degaussed it several times, the problem persists. So, I'm beginning to think my monitor is either overheating or is on its last leg. I was wondering if the 10 years of dust buildup inside the monitor might be the culprit, and I was thinking of taking off the cover and blowing the dust away with a PC duster if it would help. Also, this morning when I moved my mouse to wake up my monitor from power-save mode, it made a moderately loud snapping noise. I thought it had died, but was quite relieved when it didn't.\015

Answers :

I would beg to argue with the lifespan of CRT's. 8 years with decreasing quality after 4? Are you buying Sceptre and Komodo monitors?

CRT's should last 10-15 years. Look at my 21" Compaq P1210 from '95 - still going strong @ 2048x1536x72hz.

It seems the most common advice for problem equipment is to just replace it, but I disagree, especially in this economic climate.

I would be willing to make a bet that your fly-back needs to be replaced.

Find yourself a mom and pop shop that specializes in monitors. Shouldn't cost more than $50.
Sorry Jamess02, the problem at this point is bad solder connections. The snapping you are hearing are sparks jumping the gap. If this is not fixed soon, there will be permanent damage done that will not be worth the repair. Any shop can fix this ion about 10 minutes. Simply open up the unit and resolder any connections that appear grainy or have rings. Please note that there are dangerous high voltages present even with the unit unplugged that can cause injury.
