    curtis/proscan powerboards

    Have a Curtis pledv2480a 24" tv. Powers up to red led,push standby button,screen goes to Curtis splashscreen(a few seconds),then to source(a few seconds),then blank screen,blue light still on. If I shut down(unplug),same thing happens. Do I need powerboard or capacitors(don't see any bulging).

    Dead dps-162kp-1 powerboard
    by Danny kikkert
    Hi everyone,

    I have a dps-162kp-1 runtka932wjqz powerboard wich has no power at all on the cold side.
    I replaced ic7903, r7900, R7902, C7901, d7950.
    Checked the diodes around the chip and also the caps.
    On the ic pin 5 no voltage, pin7-8= 315V
    On the T7901 pin 1-4 no voltage, pin 2-3=315V
    Anybody have any idea where to look further?

    Any help is welcome
    Thanks Danny from holland

    Can an overheating bga blow out a powerboard?
    by dropfry
    Hello, guys. I fixed a monitor the other day, but I don't have a strong understanding of electronics and was curious about how the PFC and a couple of mosfets on the powerboard blew out. Here is what was known about the monitor:

    I bought it "as-is" hoping to salvage it for replacement parts. However when I plugged it in it powered up and worked fine for about an hour. After that the monitor's power would be very irratic and turn off and on several times. I opened it up and noticed that the mainboard had a faulty heatsink on the main BGA chip. Not only was it not making...

    Having a problem diagnosing this old tv, seems to be a powerboard problem, trying to trace the problem from power in at ac cord to power out to ccfl lamps but not doing very well in the attempt, power board there: https://www.shopjimmy.com/samsung-bn...w-605563813499

    CURTIS CONTROLLER 1264-5403
    by Éric Noiseux
    I don't know if I'm in the right place, but I'll take a chance. I would like to know if it is possible to have the boardview for this type of controller. I have a light that shows errors on the selenoid power supply. I opened the controller, I saw nothing that would indicate anything was burning. I have no idea what values I should be looking for.
    Anything will be greatly appreciated. THANKS.​

    proscan 40ld45q - no pic -no sound - no backlight - blue light turns off

    proscan 40ld45q

    Have tried published resets with no help. (unplug for 10, push on-off for 30, push menu and vol +, etc.)

    After being plugged in, red light comes on. Push power button and blue light comes on for ~five seconds then goes out. Power button does not turn the unit on a second time - have to unplug/re-plug before power button will try to start with blue light.

    No sound, no picture (used flashlight test).

    No bulging cap, no burn spots, no burn smells, nothing visual (cold joints/breaks/bugs).

    Digital voltmeter;...
