SOURCE: CRT MONITOR display

It sounds like this monitor may have what's called the "Windex syndrome" in TV repairs. If someone cleans the screen with a spray cleaner and it drips down the face, it can get onto the circuit board and cause intermittent button troubles. Sometimes it's possible to clean off the corrosion from that area, but the most reliable fix is to clean the board, replace the switches, and remove, check and if necessary replace any resistors connecting to the switches.

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.
