    Re: No picture Bush BPDP42HD2

    Hi this is exactly what I got with my set as Ron77 said. I replaced all 3 boards resulting in the same fault. The plasma panel itself gone faulty then? £60 later in boards in outa pocket n still looking at an old 28"cry. One of those unlucky years am having. ��

      Doubt it, Much more likely the replacement board/s are faulty--Have you checked the IGBT's...??

        Don't tip it, if you disconnected the cable from PSU to Xsus it does strange
        things to this set, and the result is no screen with good boards.
        The first time I done this I left the set for about a month just
        sitting there then it miraculously came back to life,
        or if you can get access to another set that is working,
        borrow the Y buffer install it in the set it should come back to life.

          Another tv engineer is testing a set overnight tonight with full working set of boards and is gonna send them to me if they test ok. Its a bit of a head scratcher. I tested the original y buffer for shorts and it tests ok which makes me scratch my head even more. The tv has same fault with xsus disconnected. The ysus board supplys the xsus on this set so its possible the xsus has taken out the ysus or vice versa. Fets on the ysus board and the replacement xsus appeared to have shorts on at least 1. Anybody had a similar repair in where the psu board maybe is faulty? The psu shuts off output when all boards plugged in and even when xsus and ysus are unplugged BUT with the logic ribbon connector unplugged from the ysus board the voltages stay stable and present.

            Got 3 working boards today from same guy who was even good enough to test them on a set overnight before he sent them to me. Y buffer, ysus and xsus boards. Tv fixed now. 3 previous sellers sent me faulty boards. talk about being led up the garden path with different faults!!! This is a horrible set to work on. Can watch rest of euros and Wimbledon now on a decent screen ��. Job done.

              T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
              by Tr0ll
              Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

              The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

              Original T-con:
              Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

              First replacement T-con:

              I thought it might be t-con and ordered new t-con from china(supposedly tested)...

              SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
              by JJAAMM
              This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

              Problem
              TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

              Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
              by TR103
              Hi, I have a Samsung UE50TU with:
              - sound and backlight, but no picture
              - when it arrived, it had a picture for a few seconds
              - it keeps rebooting
              - without ribbon cable between the two panel boards, it does not reboot but I have no picture
              - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
              - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

              - without cable between mainboard and lcd panel and with a jumpered...

              Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
              by Mgiffune
              I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

              I ordered a supposedly ‘new' Tcon board this time, and
              ...
