    Samsung LN46A550 white screen with picture fixed

    Got this TV with white screen but picture can be seen as photo 1. This is not the t-con issues, but panel problem.
    The culprit is the soldering join of VR1 on the panel driver board. I soldered it out, cleaned and solder it back, TV works fine.
    I fixed two of this model tv, same issue, and both work perfect.
    (The first one when I fixed the tab bond issues, the VR1 was broken easily when move the mental frame and the screen was white, this wasted a long time to see this potentiometer issue).

      Re: Samsung LN46A550 white screen with picture fixed

      So glad I came across this post. After twice swapping the t-con board on my Samsung TV I decided to give this a shot before giving up and recycling it. I accidentally popped off this pot removing the LCD frame but was able to clean and re-solder it and my old TV looks like new again. Thanks!

          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 QN75Q60TAF Boot Loop fixed but no picture
          by Nicktronic
          Hey, I have this Samsung TV that originally had a boot loop problem. I've isolated the pins on the ribbon cable to the panel board to stop the looping. I can hear the music on startup and when I move through menus with the remote, but there is no picture. I'm wondering what pins/signals I should look for that enables the Main Board to provide the video? Is it possible the main board is damaged? Anybody have experience wtih this type of issue?

          Thanks!
