    I can, I do repair monitors, big small and all kinds
    Have you got any repair experience?
    Tell me how much you know about electronics and voltage levels in Monitors.
    Is it a CRT or LCD?

    Unless you have a good deal of experience plus test equipment, monitor repair is very difficult. A CRT monitor has several dangerous voltages present - up to 32 KV, depending on the size of the screen.

    I worked in a university electronic shop. We abandoned monitor repair as it was too difficult to make repairs with no schematics. Collectively, we had over 100 years experience in electronics, including TV's, which are somewhat related.

    OK.. so you'll need like a DMM and Soldering station.
    Plus...these too. :p
    Do you know how to solder?
    Do you know how to measure DC voltage and AC Voltage?
    Do you know if you see a HV Area and LV Area of A PCB?
    Do you know how to identify components?

    Only with these knowledge I can guide you, other wise I might be responsible for electrocuting you. Now I can't have that on my conscious. Can I?
    :D

    Just note,benethere you could not find enough spare parts
    over a period of time to repair one. What main part was the most hard
    to find. I just picked one up from trash pile to explore.I have two high
    voltage probes-25-35-kv.I was just going to look at how It was put
    togather. Any advise other than be careful,I will discharge hv.
