Acer CRT screen display just got permanently narrower

This 7-year-old Acer CRT monitor that I've been using started flickering a little and then something suddenly happened to cause the screen to permenantly get narrower. It's not the computer, because I had two computers connected via KVM switch and it happens with both regardless of the screen res I select. It's not the KVM switch because I tried connecting the monitor directly and it still happens.

Is a narrowing screen something that typically happens when an old CRT monitor is dying? Even if I increase the geometry settings, the screen display still is narrow. Also sometimes the power LED appears not to be as brightly lit as usual.

Is it time to get rid of this monitor?

Thanks,

J.

If with 'narrow' you refer to the pictures breadth, then two things may have happended

- the deflection current is smaller

- the anode high voltage of the cathode-ray-tube is higher. The cause for both deviations will have to be found in the innards of the device. Often it is just a failed capacitor, but which one?

This may happen with a new device as well. You can usually not assume that all parts in a device age with the same speed or start with the same health.

You will have to decide this on the basis of your preferences and your economics. If you find a freak who likes to repair monitors, you may well regain at low cost a device that serves you another 15 years.

Some of us who repair monitors to help keep them out of landfills for a little longer really do not like to be called "freaks".

Without a model number, all you wil get here are generalizations.

After 7 years, it is probably still fixable. But, you didn't say how the overall picture quality was before the series of events. If everything else was ok, it might be worthwhile getting it fixed. You would have to find someone who is willing to look at it and give you an estimate. After 7 years, it probably is marginal to spend the money, especially when new CRT monitors are so cheap.

Dear Bob, please allow me aboard the little boat with the rest of this nearly extinguished species of CRT-monitor-repair-freaks. I call myself such a freak, too. We here in Krautland call somebody a freak who does, other than the dumb public, devote a special interest to something and develops a special ability in that area.

Here in the USA, the word has a more sinister connotation, such as the Virginia killer from last week.
