    Bush BPDP42HD2

    Hi All,

    New to Forum, I wonder if anyone can help me with the above model Plasma.
    It is a Bush in name only and has Samsung everything else,

    This is the first Plasma I have looked at ,done a couple of LCD's
    power supply's , but manly CRT's.

    History bought without picture , Traced fault to short Y buffer taking out Y main and X main.

    Picture back on but everything on screen to the Right programs Menu's Graphics

    Set VA, VSC and VS to spec but no change only thought left Logic board.
    Pictures follow

    The plasma panel is likely defective. It is a common issue with these Samsung panels.

        Likely that line is what took out the buffer in the first place. Yes newer single-pane-of-glass Samsung panels suffer from this a lot.

          When I first put it back together, there was a large black bar and about 10 lines underneath it, it looks a lot better now.

          Apart from the central issue.

            Do Samsung LCD's, suffer the same sort of Failures.

              Yes, though typically more vertical lines, their plasmas have horizontal (like yours) and vertical line failures.

                  That's nice to hear you fixed the line, it's rare to find that to be a loose connection so you got lucky.

                    Hi
                    Can I ask you when you had your no picture problem where you getting the correct voltage at test points Vs 207. Va 55 ? Its just I have same model & i'm not getting Vs & Va voltage ( when I first turn on it measure correct for a second) The only voltage's i'm getting are the D15v on cn804 & the voltages on cn802 Disconnecting y& z bds does make a differance

                      I had something similar with a 42B456.....

                      Some dumbo had changed the panel-options in the engineer menu to a 19" LCD!

                      Correcting that, and everything was restored to normal.

                        Need help identifying an IC chip on a Bush DAB radio (BD-1801)
                        by tyler123456
                        Hi,

                        Not sure whether anyone can help but I'm trying to identify the IC chip in the photo below.

                        I purchased a faulty Bush DAB radio (model # BD-1801) and identified that an IC chip was blown on it. Unfortunately, I couldn't read the manufacturer name / model number of the IC chip.

                        I purchased another (working) BD-1801 so that I could open it up to find out the IC details - but the IC chip details are missing (as you can see in the photo.)

                        Given the two huge blobs of solder either side of it I'm guessing it regulates power(?)

                        Anyone...

                        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...

                        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...
