Question about LG Flatron 915FT Plus (White) 19" CRT Monitor

1 Answer

Image width instability

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?

Crt Monitor Macer Model C708 as soon as i connect the power cable there is no power, no display

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 setup menu on your monitor needs to be changed. On most monitors there are buttons which you press in sequence, go through these buttons and you will find a monitor mode which allows it to stay on permanently.

Mitsubishi monitor is distorting the picture

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!!!.
