Hi,

All CRT type monitors have an FBT that supplies the high voltage to the tube. Additionally, it also supplies the G2 voltage that is responsible for the screen voltage. Often the adjustment for the Screen/G2 requires a bit of tweaking after some time of usage. Incidentally, there is another adjustment in the same area for the Focus control. Of course, adjustment would have to be done on a "live set" and on the high voltage section, extreme caution must be exercised when performing this operation.

In some extreme cases, it could be a cold solder or loose connection in the squarish PCB at the very rear of the tube. Alternately, it is also possible for a capacitor that is nearing end of life (dried up).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Don't know how to decrease the brightness. It's straining my eyes. When I push the front bottom Menu button, a rectangle appears with the word Brightness, but I can't find how to decrease it.


Here is a manual for a Daewoo Monitor. On page 3 it indicates that there are buttons that show a right and left arrow above it. When you have the brightness menu highlighted press the left arrow button to decrease the brightness.

Decrease Brightness (fn+f7) The fn+f7 hotkey decreases the brightness of the notebook screen. The longer you hold down the fn+f7 hotkey, the more the screen dims. Decreasing screen brightness conserves power. » To increase screen brightness, press the fn+f8 hotkey.

Display is not stable.


There are a couple of possibilities and none of them lend themselves to DIY repair. It can come from arcing in a component trying to fail; you may be able to hear this (if present) by listening closely near the rear of the housing, preferably in a quiet room and near the cooling slits.
Another potential source is what is called a 'cold solder joint' that may look and even measure OK until a little more current is flowing through it.
Neither one is something most users should try to deal with unless you have some technical background since having a powered, open, circuit board can be very dangerous; there are voltages greater than 20,000 volts and several other innocent looking places with many hundreds of volts with sufficient current available to kill.
The only thing you should try on your own is cleaning the guts free of built-up dust that naturally accrues in any high voltage device. Pull the AC cord, ignore overnight, then remove the few screws you will find, often behind the bezel and perhaps a couple in the rear near power cord and video connections/cable.
I like to do this with the monitor laying face down on a soft surface so with most housing you can simply lift the housing free of the bezel and put it aside. With a vacuum cleaner and a clean paintbrush, clean all the areas you see that have obvious build-up of 'fur.'  Try not to disturb any parts in the process though, some are fragile. If the bottom of the circuit board is visible, clean that too and look for any dark brown areas caused by heat. These can become conductive if approaching black in color.
You will see a fairly fat cable leading from a black lump on the circuit board; this is a transformer responsible for producing the 20-25,000 volts. If the unit has been off overnight, you can clean enthusiastically around the rubber cap you see on the side or top of the picture tube; this is a good leakage point for high voltage.   
If you do this and it didn't help, you will have to find a surviving CRT monitor tech to take it from there.
