I cannot bring myself to chuck this perfectly good monitor away - as advised! No-one local seems to consider it (or any CRT monitor for that matter) an economic repair.
The problem started intermittently a couple of years ago when, apparently when warmed up, the monitor gave a "click" (relay?) sound from the back and the screen went "wide" with its edges outside the physical limit of the crt. The only way to see the edges was then to re-size the image using the touch controls on the front. This adjustment was obviously well outside the calibrated width range and the edges of the image are now cylindrically distorted.
The problem became less intermittent as time went on and now the monitor normally starts "wide". I have taken the cover off (with due consideration of CRT HT issues) and can see no obvious signs of component overheating or other failure.
The monitor also had image flicker problems which are probably are a related issue - they seem to have stopped now that the width fault has established itelf!
Any ideas?
Thanks - that was an amazingly fast response! I tried what you suggested a while back and have done so again on your advice. The image seems stable at both higher and lower res values/formats, but the one we prefer is the unstable one. I suppose that the fault is with the circuitry that controls the format/resolution, but to be honest I am not really sure what to look for to trace the fault. If you have any further thoughts I would be grateful to hear them. Thanks again.Thanks - that was an amazingly fast response!

Actually, banging on the side of the monitor did originally partially sort the problem - for a while. I suspected a dry/broken solder joint and months ago took the cover off and in one circuit module found a bady soldered joint - which I resoldered. It seemed to reduce the problem, but did not fix it entirely. I concluded that the bad joint was just incidental.

try tapping quite hard on the side of the monitor....any changes? if not, the problem may be with the vertical drive circuit as it cannot "stretch" the image from the top to the bottom. As last resort, search ebay for AS-IS items and get one for part-swappingtry tapping quite hard on the side of the monitor....any changes? if not, the problem may be with the vertical drive circuit as it cannot "stretch" the image from the top to the bottom.

Wide screen monitor distortionDepending upon the screen resolution that has been set inDisplay, the image will be distorted on these large wide screen monitors. Create a large circle image using a draw program such as Paint (hold down theShift key as you create the circle as it will draw a perfect circle). Open Control Panel - Display - Settings tab and adjust the Screen resolutionslider, increase or decrease the screen resolution then bring the circle imageto the front and check the image, if the circle is still distorted then changethe screen resolution and check the circle again until you are satisfied withthe image of the circle. When you are satisfied then click apply.
You could do it with some specialized hardware converters and adapters but the image quality would not be very good, so why bother?
People are just giving away their perfectly good CRT computer monitors for nothing these days after they upgrade to LCD flatscreen monitors.
Just look around in your local online classifieds (or place an ad yourself) and I'm sure you will find a bunch of them available for free.
Good luck.
Have you checked that power is reaching your PC? First, check your power socket by plugging something else in. Next, you need to check the monitor's power line.If it has a fuse in its plug, check that by substitution if you don't have a test meter.It is very unusual for the power lead itself to get a fault because monitor power leads are heavy and of good quality.
It is possible that an internal fuse has blown, but if it has, there must be a cause. I would not advise you to even check that due to very high internal voltages even when power is off. Unforunately, CRT monitors are worth so ilttle these days that they are not worth repairing. Your best bet is to find a used monitor locally, which should not cost you much because they can hardly be given away these days.Look in your local papers.
The monitor is probably faulty. To determine if the monitor or the video card is faulty, connect a different monitor to your DELL. If the image is OK on the other monitor then the other CRT monitor is faulty. Repairs to the CRT monitor may not be a cost effective solution, I suggest you buy a LCD monitor.
The CRT has screen adjustments, there is a screen adjustment button on the monitor that will allow you to adjust the width of the image as well as the height etc.
You can adjust the keystone of the monitor.. this will remove the trapezoidal shape and square up the image to the monitor. Check on the monitor for the menu controls and you should be able to find the keystone adjustments... allows you to adjust the upper width, lower width, etc...
well first af all ,you never find this "loose wire" because it is a mith.
what you have is a "cold solder" in the vertical IC, if you have a solder iron , and the ability to open it (without scratching),
and then take off all the shields (without cutting your fingers), and get the solder area (without breaking the Tube).
at this time ,it take you 1 minute to solve...!!!
iF not... leave it to the repairman!!!.
