Computer monitor repair?
 

I have just been given a computer monitor. The problem is the screen is
rather dark.

I have the settings of brightness and contrast up to 100, which is the
highest it can go.



What is the problem here?



Can the brightness be turned up inside the monitor?



In TV sets there are various variable resistors that can be turned to
increase the brightness.

Does the same exist in computer monitors?



Thanks for all your replies.

May need to post this to your Generic Monitor Repair Synod. Without any idea
of what product your are attempting to play with we can give you hardly any
pertinent information, other than take it to your local generic repair
facility.

Paul:
Yes, like a TV set, most CRT monitors have a screen control on
the high-voltage (flyback) transformer. The one with the big red
wire going to the top of the picture tube.
The screen control is the lower control. 17" and larger monitors
have 2 focus controls and 1 screen control. Smaller monitors have
just 1 focus control.
Note: some monitors do not have screen controls and you have to
manually change a resistor in the screen circuit to control
the brightness.
