If the > only choice I have is throw the monitor to the garbage, I'll take a look. I expect he knows enough to avoid the dangerous bits. After uplugging the mains there's dangeros voltages stored in two main places inside the picture tube, and in the reservoir capacitors, these charges need to be avoided or dissipated. If the fault is aging capacitors (and not a dodggy joint), it's a more involved task... Don't ask you friend to fix it for you. (he probably gets that line from too may others already) but he be able to give you some pointers, (and can probably tell your skill level better than I). Bye. Jasen
