Help me repair my monitor... need professional tips....

[THE V_I_R_U_S]

OK, I have a MicronPC 19" flat screen monitor that has few problems which I know can be fixed but I am not sure how. I can't afford to spend alot of money tsking it to a repair shop.

Ok, heres the problem.

First of all, in the lower left corner, there is a little patch of the scree that is slightly blurry and slightly off-color. It looks like magnetic disturbance or something. I degaussed the monitor, then it goes away, but in a few minutes, its back again. I looked for the obvious.... something near the monitor that might make it do that, but i saw nothing. I unplugged the monitor, inspected it, and saw nothing unusual. So I moverd the monitor to about 15 different places, far away form magnetic sources, and it still happened.

Next, over time the entire screen will get really blurry. It starts out fine, but slowly gets blurry after about 15-30 minutes. It looks like the red/blue/green colors are drifting apart maybe? you see red "shadows" coming off the text, on the left side of the text or picture of whatever.

My computer teacher at school ( who is an expert, and actually owns one of those ancient goliath computers that take up an entire garage) said it may be a bad transistor? that is supposed to keep everything lined up horizontally? Although he's not all that great with monitors he knows mere than most people.

I don't know, but please help....


Yes my typing sucks at the moment... I using a laptop.

i dont know about monitors but, my big screen tv started to do the same symptoms not the patch thing but the seperation thing.. and the tv repair man said it was a transitor and some other part that stabilizes the screen... i dunno flat screens have come a long way since my 8 yr old big screen

Just to clarify - I had that issue on a Micron 21" Trinitron - that is what you mean by flat, right? That it is a flat tube, not a panel- just my understanding of that post... (Don't have an answer, but clarifying it for anyone who might look at it)

yeah Granite just a suggestion but you might want to look at the thread dates so that 4y/o threads can die peacefully

The colour fault could be caused by a problem with the shadowmask. If so, it would take a new tube to fix the problem.
IMO, the blurring is likely caused by out of specification parts. As they heat up, their electrical values/properties change. As the colours are all drifting, it may be a problem with the focus control circuit or the circuit controlling the EHT voltage.
CRT monitors and TV sets are NOT safe to attempt to repair by yourself.
