Monitor - adjustments stuck problem

[Chaos Master]

Vitech DX-1564 monitor. Made in Brazil IIRC.

Problem: The adjustment buttons are simply not working. If I press them REALLY
HARD, sometimes they work. This problem sucks as I often change resolution and
work with DOS programs.

I've Googled for it. No luck!
If someone has a service manual, a schematic or a solution for this problem,
please reply.

Thanks.

More than likely liquid damage to the switched themselves as they are
located on the pcb just under the crt. Very common problem for people to
spray cleaner directly on the glass and have it drip down into the switches.

You simply need to take the monitor apart, identify that the switches are
bad, buy new ones and replace them, solder in of course.

OK! Thanks!
