    KDL-70R550A Peeled off LCD Tabs on left side and perfect picture for 5 minutes

    Hi Guys,

    Thought I might try and seek advice on an issue I am having, I got this SONY tv for free that was having some dark greenish colouring, I replaced the T-CON and too my suprise the TV would not boot - I would get 5 blinking red LED lights. I dug deeper into this forum and someone mentioned the fact that it might be the tabs that connect to the LDC panel, and peeling them off should bring back a clear image. I tried this on the side of the T-con that was causing the tv to not boot when plugged in (left) and wow a perfect picture and was booting up fine! All was well and good for around 5-10 minutes and then the TV started glitching out and colours going crazy, flickering a what not, I have attached a picture of what it looks like right now.

    Also another notable thing I should mention, is that the colours went wackey and then I left it over night and turned it on this morning and it was working fine again, for about 5 minutes and then the same thing happened.

    Let me know if anyone has any ideas as I am shattered to see it not working!

    Thank you all heaps!

          Hey mate, sucks to hear that. May I ask how you came to this conclusion?

          Thank you

              Im giving answers purely based on my experience and the pictures that you posted. Horizontal lines most of the times means a faulty screen.

              Next time try another approach and don't mess with the screen at first. Try mainboard, psu, tcon. Everything is replacable except for the screen.

              I think you should try selling the board on ebay for a profit.

              But lets see if there are any other members that might offer you a solution.

                  since you played with cabling as part your testing / checks.... check to ensure all the cables are seated correctly as even a bit of misalignment or damage to the ribbons can be a problem.

                      70LE660U dark cloud or black screen with sound.
                      by Rozp
                      Hello Everyone,

                      This is my first post so I will try to be as precise as possible without making this post too long winded. Unfortunately I don't have pictures of the original problem but I included images of the TV internals.

                      I have a Sharp 70LE660U. The problem started a few months ago with the bottom row looking out of sync and was dark on the left side and then fading to transparent on the right side. Shortly after, a dark cloud appeared in the center of the screen. The dark cloud started small and shaded but the image was visible. It also affected the menu area....

                      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 ‘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                      ...

                      TCL 55US57 backlights, no picture.

                      So here we go with another screen short TCL. For this exercise left and right will be reference looking at the screen.

                      The person I got this TV from said the color was bad in a vertical fashion about 1/4 of the way over the left side of the screen. Shortly after the symptoms below started.

                      Power Supply, main and T-CON board are working.

                      Symptoms: The TV has backlights but no picture with both FFC's attached to the T-CON and does not respond to the remote or buttons, and the TV appears to continuously re-boot.

                      Unhook FFC from left side...
