blurry screen

Sep 23, 2004 1:01PM PDT

Okay, I have Windows XP and my problem just started yesterday. After I had went and turned on my computer, I got on the internet. Well, a couple minutes pass and I realize that my screen had gotten blurry (letters and everything). It happened today as well, and it's really getting on my nerves. If anyone can point me in the right direction and help me get my problem fixed, please by my guest.

Since I am not there, this is difficult to troubleshoot.
1: Did the resolution change? High res on a not good enough screen will be blurry.
2: Monitors do get old and get out of focus.
I do not recommend this unless you are qualified, but most monitors have a focus control inside near the back.
If you remove the cover (powered off) and find the control, usually very small and uses a small screwdriver to adjust, you can boot (cover off) and adjust the focus back to sharp. I have seen some that had many controls for brightness, rotation, etc. If your test each one you can find the right one.

If you are not very careful, you will end up ELECROCUTED. This is why I say qualified. If it is a 17" and you are not prepared to take the risk, just buy a new monitor.

Talbot has a separate inquiry about this.
Anyway, you are correct that it really is very risky unless you are a qualified technician to play with the inside controls of a monitor.
There are three small square tower like parts in the monitor board. They are "quartz" parts that control the RGB colors (red, green and blue) gun that is shot in the flyback then the CRT, it controls the mix of colors but not the blurry appearance. Opening a CRT housing takes courage (imagine a 33,000 volts power in it) and knowledge about electrons, electricity, capacitors, stored powers, grounding, power release and the kind.
I agree with your position but there might be people who might try the procedure and end-up being electrocuted.
Leave opening CRT's to qualified individuals. THis is just a reminder, life is precious.

By the way, you need an oscilloscope to do some adjustments in brightness, color mix, color balancing and the like in CRT board which can be simply done by video graphics card controls in the system.
The trial and error mode of adjustment is time consuming and more accident prone.
