    Need help new member plasma tv

    Hello all. I have a techview 42" Plasma tv model number pstw4200u. The problem is the tv picture flashes/flickers very bright but the images appear ghostly. It will do this for a few minutes then the picture will return to normal, 5 min later it starts all over. It does this with all inputs including DVD player, cable and video games. What part or parts should I look into changing?

    Thanks in advance

      Why did you not post pics?
      Just cook it! It's already broken.

        Samsung PS51E550 Plasma TV
        by ArMaaN376
        Hello,
        I am having Samsung PS51E550 Plasma TV. While the TV was working, a crackling sound heard & video went off with audio still ON. After switching it off & ON, the red LED on TV blinks six times & then off.
        Opened TV cover & observed foll
        a) Green LED on the small PCB blinks at @5-6sec ON & off for 3-4 secs. Red LED on logic board ON
        b)Vs & Va on power supply board raises momentarily to 209v & 58v resp & then drops.
        c) Cold test on Y-main board shows all 3 pins of FGPF4536 IGBT short to Grnd.
        How to confirm Y -Buffer board...

        Panasonic plasma TX-P42ST50 - 6 blinks
        by jm1234
        Hi,
        anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
        It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
        I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
        I checked that board for any obvious faults...

        Hitachi 55HDS69 55" Plasma TV - No Picture But Sound
        by KYBOSH
        Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
        No picture but you hear the TV static (white noise) playing loud and clear.
        The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
        But it seems they didn't get too far and just left it.

        When I first took a look I was amazed at how pristine the inside looked.
        Its as if the TV had been in a time capsule.
        Caps looked like they were just pulled off the self.
        Copper coils had no sign of corrosion on...

        Schematic or datasheet for Plasma TV buffer chip
        by Yanleb
        Hi all,

        I'm interested in understanding how a buffer board chip is working. I know there's about 90 outputs per chip to the plasma panel, but I'm more interested to know about the input pins. I guess that some of them are address pins, but I want to know more.

        So far I've found nothing at all. I haven't found any datasheet about the various buffer chips, and I haven't found any schematic for the buffer board using them (Y Buffer Board in Samsung's terminology).

        Any information will make me happy. It can be from any buffer chip or plasma TV manufacturer....
