Crt monitor gradually develops a yellow tinge after being turned on for a few minutes. It fluctuates annoyingly. It is about 4 years old. It is a Samsung SyncMaster 753DFX Crt monitor.


CRT monitors have three color "guns" in them - Red, Blue, & Green. If one of them is starting to go south you will have a tinge as you describe. To make sure it's the monitor, try connecting a different monitor. If the monitor is the problem, it's not worth fixing. Replace it.
If, after changing the monitor you still have a color tinge, you have a problem with your video device in your PC and you need to have it checked out by a PC Technician.

Viewsonic VG2021m Image Vanishes on Start Up


Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank after a few seconds, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Optiquest monitor screen turned bright pink. How to solve this issue?


First check your cord from the computer to the monitor to make sure the connections are clean and good on the blue vga cord. Plugging it in and out a few times will help clean the pins and holes.
If that is ok: then it may be bulbs.
Pink means that you have bad bulbs inside the screen. sometimes the pink goes away when the bulbs warm up. eventually it won't stay on.
There is a slight chance the power board is also getting weak. You would have to open it up to tell this.
Once partially opened, Disconnect the wide set of wire that goes from the back of the screen to the monitors main video board and then try to turn it on, If it is still bulbs they will really show up with this setup.
If you send me a picture of the power board to bammbamm@ptd.net, I may be able to tell if the board has issues by looking at the picture of it.

If you mean 'flyback' or 'horizontal output transformer' and have the part number available, try one of the sources here:
Flyback links 
If you do not have the number you may have to search Viewsonic's website to loacte it.
Warning; the number of suppliers for CRT monitor parts is shrinking rapidly, my best supplier, ICM in California is long gone.

Screen flickers


The problem is that it is on the verge of going out my mother had a monitor go out and it did the same thing. Also if you have any high frequeny things around your monitor thatr also migh be the thing. Try a magnet or demagnitze the screen if you have one on it.

Havent you got a person or a friend that has a puter to test the monitor??? This would be the best way as it could be the crt on the monitor or the crt driver board but before we go there we should make sure where the problem lies. Good Luck
