    Samsung UE46B7000 Picture Flashing

    Hi, I have a Samsung UE46B7020WW led tv. After being on for an hour or so the picture flashes on & off, sometimes showing a black & white chequered screen. It happens on all source inputs and the menu screen.

    On service mode all 'FBE' & 'FRC Before DDR' test screens flash but the 'FRC after DDR' test screens are fine.

    I've seen replacement T-con and Power boards on ebay but am not sure if one of these will cure the problem, or whether the display itself is faulty.

    Any helpful advice would be great.

    Thanks

    Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

      Of course, rookie mistake! I've attached photos showing details of the Main, Power & T Con boards, hope this helps.

        Does anyone know the difference between the FRC Before DDR tests and FRC After DDR tests? What does it mean if the picture is faulty before but okay after?

          It means the Frame-Rate Corrector, on the T-con board, is faulty - so you have narrowed down the problem to the T-con.
          Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

            Thanks Tom. I've seen some T-con boards for sale, same part number, but for 40" displays. Is there any difference?

              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 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 LE37A656A1F TV, No Picture, LED Flashing Continuously
              by estergon2004
              Hi,
              Samsung LE37A656A1F
              TV turns on, no picture, LED light flashes very rapidly and continuously .
              Sound and Backlight are OK.
              It didn't happen at once.
              In the beginning picture was coming about 15 mins after the turning on.

              What could be the problem please?
              Thanks!

              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
              ...
