    Samsung LN40630

    Need a little help with diagnosing, I reset all the cables and have a picture and sound. However the picture has some ghosting and horizontal line problems. I am wondering if anyone can help. Hoping maybe its just a tcon board.
    Photos attached. Thanks.

    Re: Samsung LN40630

    Looks like bad panel to me. Did you try flexing the panel to see if it will change?

      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 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

      Samsung QE55Q60RAT - no picture
      by YellowJacket
      Hi friends,

      a friend of mine gave me this TV to fix, with common SAMSUNG TV issue - damaged panel. Turning on, sound is present, but no picture. So I went directly to standard process, connecting two pads together with a wire ( see in the picture ), and then removing flex cables. With right flex connected, there was half screen working, but still no picture ( disappearing colors and similar weird stuff ) + working sound. With left flex connected, TV is restarting + working sound. I supposed, left side is damaged, so I then blocked all 8 CLK pins ( going from 0R resistors on the second...
