Monitor Repair Manual

By on September 13, 2007

 monitor repair manual

At the beginning, you need to depends on monitor repair manual to understand how Monitor circuits work. After you had familiarize how it works, i suggest that you  depends lesser on monitor repair manual. By constantly depending on the manual won’t bring much benefits to you as you may think that “with monitor manual then only i can repair a monitor”. It is a wrong concept. You should say, i could repair most monitor even without a schematic diagrams. That’s make you different between an amateur and a pro. However sometimes we do need to refer to schematic for reference like identifying burnt components, look out for missing components part numbers and etc.

Don’t get me wrong, it’s good to have a Monitor schematic diagram besides you but it just that do not fully dependant on it otherwise you may not be able to troubleshoot Monitors that you can’t find the schematic for it.

    Hi Birac,

    Try visit http://www.eserviceinfo.com Backlight turn off could be problem with the filter capacitor, dry joint/bad components in inverter side and bad backlight.

    I need a schematic for a METRO 19LS monitor (Future Shop), need to check capacitor values, changed a few to correct a problem, may have misread one, need to varify. I have already checked http://www.eserviceinfo.com, and so far it hasn't helped with any of my projects. Seems to be a useless site for most people searching for schematics, but I did have a posting for the monitor already, just in case miracles happen. Any help is appreciated.

    horizontal out transistor c5521 immediately burnt out if ireplace.
    1.What harm will be happened if i remove the connection of EHT with collector of c5521?
    2.What harm will be happened if i remove the connection of horizontal deflection coil with collector of c5521?

    Hi Chanchal,

    Please visit this link:

    If you remove the connection, sometimes it will cause the HOT to get shorted.

    Dear Jestine,
    You are right its a bad practice to depend on manual. I use to repair TV sets and i can do it without manual. But this my first encounter with Computer Monitor. I have an LG Faltron T710SH. MOSFET 10N20C overheat and blows off but HOT is intact. I have replaced the EHT and disconnected the Horizontal Yoke. Still the FET blows again. I have check the Horisontal driver but fond no problem in it. Can the defect be in the secondary part of the EHT ? Plz help me.

    Hi Raja,

    Try remove the B+ fet and power on and if the monitor working with reduce display then suspect a bad safety capacitor that is located near flyback. Sometimes a bad gate signal to the B+ fet also could cause such problem. Try replace the H/v oscillator ic and retest.

      Hi Jojo,

      So far I have not encounter such a link. I was informed by one of my members that there was a good book on this subject. Check out the link below:
