    hi earl
    welcome to the forums :)

    first educated guess would be excessive voltage. possibly some component is faulty that is a load after that resistor.

    Have you tried to get the service manual or at least a schematic online ?

    Hi Dave'
    Thanks for the kind response.
    I've tried relentlessly to find any bit of information on this particular model of SHARP MONITOR CHASSIS (Si-727r-ds) but to no avail.
    Can someone please post schematic diagram for this chassis or tell me where I can get a copy.
