    I check all the voltages on the Assy PCB P-SMPS card.

    VA 70.8vdc

    VE 90.9vdc

    VS 209vdc

    Vset 197.6vdc

    Vscan 192.6vdc

    VG 14.9vdc

    5.3 = 5.3vdc

    All the fuses are good to go.

    vset 195

Just check the voltages and refer to the sticker on the back of the panel (inside) Should read VA, VE, VS, VSET, VSCAN, VSUS,VSUSTAIN, ETC. And see which ones are missing then write them down and we will go from there. See if any fuses are blown as well. Just check those on the Ohm check. Or diode check is handy as well for this. Let me know if i can assist further. GURU JAY

    VE i thought should be around 60vdc and Va At about 100vdc or so. What does the sticker on the inside say. Usually in upper right corner of panel. Voltages should be close. Let me know.

Samsung plasma hp4252 type sr42p5 faulty screen

Most likely cause are leaking capacitors in the power supply, however I've seen the convergence IC cause the same problem. If you have a good ERS meter and are willing to check parts one by one then start with the DC side of the power supply. I fast scope makes this easier. There are a lot of safety precautions you need to be aware of. These are listed in the service manual, which you'll have to have to do this kind of work. If you don't have any of the above then I wouldn't recommend you try to tackle this. Find a reputable repair person.
