    LN46A550 P3F samsung picture problem

    Hello, I have a LN46A550P3F SAMSUNG, who just started this problem. When I turn on the TV, my picture is dark on the right side (see Figure 1 and 2) after a few minutes, the picture becomes beautiful, but after a few minutes, there are three horizontal lines always appear to the right (see photo 3)
    and immediately after, the image becomes darker. this problem
    can last 30 to 60 minutes after the picture remains clear until
    During closure of the television. Thank you to find a solution

      It looks to be bad tab bonds on the panel. Follow this link for instructions on how to "fix" it.

          sorry for the response time, I went to see the link but I do not understand the explanation. here is a picture of the TV, I know that the t-con is good, but is it possible to tell me what room or in connection just that I have to check.
          Thank you in advance for answers

              Bad Tab Bonds... Yes there are temp "fixes" but is classed as an irreparable fault.

              You have to open the actual panel to get to them.... good luck

                  Samsung UN55MU8000 - Backlight But No Picture Problem
                  by KYBOSH
                  Hello all

                  I pick this up free as a repair project for the holidays.
                  The original symptom was power cycling after 3-4 seconds with a single red light flash.

                  To remedy this I went through and unplugged each component 1x1 and discovered that when the FFC cables were disconnected the backlights stayed on and the TV did not reboot.

                  I tried remove one or the other to see which side of the display was causing the issue (expecting to see half a picture to show) but didn't see anything. But the boot loop only appears when the top FFC cable (right side...

                  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 QN75Q6DRA, No Picture, Has BL, and Sound
                  by Dodgethis
                  Hello all,

                  This is my first post, but long term lurker on the form learning as much as possible about these TV's. I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where...
