THERE MUST BE A PROBLEM WITH THE VIDEO PROCESSING CIRCUIT LOCATED AT A PCB CIRCUIT ATTACHED AT CRT BASE. THERE MUST BE SOME DRY SOLDER OR A FAULTY BASE CONNECTOR WHICH CONNECTS THIS CIRCUIT TO CRT.
YOU CAN ALSO TAKE A TRY JUST AFTER PRESSING THIS CIRCUIT FIRMLY TOWARDS CRT BASE.

MY COMPAQ 7540 17" MONITOR OPEN MENU AUTOMATICALLY


The buttons in front of your monitor is a toggle switch. This kind of switch is that when ' they get older they produces resistance and works with their own way, without pressing them. if you can do open your monitor you can do replace it.

1. prepare the following:
* screw driver/soldering iron/soldering lead/paint brush to remove melted leads.
2. remove all the toggle switch, replace all of it if possible, don't worry its really not expensive, it just cost about 12-15 pesos each.
3. then put in the new switches and try to put in the way it was before.
4. close back the monitor. this is 99.95% sure.

note: before doing these, unplug the wire from the outlet to avoid electric shock.

DELL 2208WFP LCD-Comes on normally, but almost immediately goes dark You can see something on the screen if you look closely. Turn it off and back on you see it then dark. any help?


Hello,

I believe the power led button is still on while the screen goes dark, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes dark after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes dark.

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

Take care.
