    I realize from your introduction that English is not your native language.

    Hopefully with using Google translate, it translates okay.

    We normally ask people to post clear focused top down pictures of the boards. They should be uploaded here using the manage attachment function.

    This is the picture composition that we want.

    After we get the pictures, we can make suggestions on what to test.

    Schematics are hard to find, but some manufacturers use power boards that may shared among many.

      Here is the main board
      I can't to disconnect power supply from logic to test only power supply. There is one relay who does not want to switch.
      now I will measure all voltages from main plug to power transformer and after him.

        Darn, I didn't realize this was a CRT monitor. My knowledge is this area is zero. Hopefully others can make suggestions.

              Good luck.

              The main reason I have no experience or knowledge in the CRT world are two fold.

              1) People are giving away these CRTs for free on a daily basis.

              2) I understand there are very lethal voltages so I would rather not deal with such devices.

                If I recall correctly, PlainBill has registered and said there is no spam/junk from that site. When registered, you don't have the 2 download/daily limit.

                Okay, I found it.
