... диагноз...: QUESTION NO. P1011-3: Sampo Alpha Scan 950 monitor, will not light up, just ticks. Can this be the high voltage power supply? If so where can I find this part, I`ve searched everywhere?
If your everywhere includes the HOT, damper diode, fast rectifier diodes, diodes around the deflection circuit, no bulging or shorted capacitors, then I suggest that you check the flyback. I have refurbished many Sampo flybacks before, they tend to have an open capacitor or shorted coil. To confirm, ring the flyback. To check the capacitor in the flyback, connect a capacitance meter with 20nF range and measure the internal flyback capacitor from the anode cap to the ground/ feedback pin on the flyback. You should get about 1.5 to 3nF. Much more or much less, you have a problem.
