    Heard a loud pop. Then no picture

    The model of the screen inside of the TV is pdp42x3####. I found a blown fuse. you think if i replace the fuse it'll work or may need a new board. model on board is 42v8&x3 and part # 6870Qyh005b. Thanks

    After a lot of reading I need a Y-Sustain Board due to the hybrid shorting.. Where is a good place to order one from. Thanks

      1. Please do not post pictures inline. They cause problems for people with slow connections and irritate many of the rest of us. Instead, use 'Manage Attachments' - below the text entry area.

      2. eBay. Use the part number on the white label on the sustain. However, there is an adjustment on the Y-sustain that requires a 200 Mhz oscilloscope to perform correctly.

          I have one of these.

          How difficult are these to open?

          I think the sustain board on the right side with the black heatsink is what needs to be replaced.

            If you have to ask, you shouldn't be trying it. Besides, the service manual is readily available.

            Either can fail. Since the OP didn't give much information, I didn't give much advice; just took it on faith that he did the diagnosis properly.

              I have the service manual. Just wanted his opinion... This has been sitting in my closet for a while now. Just don't have the funds yet to invest in it.

                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 β€˜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 β€˜new' Tcon board this time, and
                ...
