    Samsung UE75TU7020k No picture, Standby blinks 2 times

    My Samsung UE75TU7020k lights up fine when one of the ribbon cables are disconnected from the main board, lights stay on but not getting half a picture, I do the same with the other ribbon and put the other one in and lights stay on but not getting half a picture. The standby light flashes 2 times then reboots then it then tries to come back on again and just keeps looping until I take either one of the ribbon tables out (doesn’t matter which one I take out it stays lit when either one is out). I’ve tested the backlights but all working with none shorting out, I’ve replaced the main board but no success. Is this a panel fault or the power board? How can I test if it’s a power board fault if so? I’ve attatched pictures of my power board.

    Any help would be greatly appreciated! Thanks in advanced.

      It's a panel fault. Take a pic of main board full pic and one closer to ribbons

          T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)

          Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

          The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

          Original T-con:
          Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

          First replacement T-con:

          I thought it might be t-con and ordered new t-con from china(supposedly tested)...

          Samsung UN60F8000BFXZA ~ No Picture or Sound - 5 Res Light Blinks
          by kca
          Hello all ~

          I’m working on this Samsung 60” LED and purchased a new main board a couple of days ago that did not fix the 5 blink issue. The original main board’s HDMI ports (all 4 of them) failed to work and no amount of reflow remedied that.

          This 5 red light blink code on the front panel LED is followed (about 15-20 seconds afterward) by an automatic reboot, and results in 5 more red light blinks. Then the entire cycle repeats itself indefinitely.

          No picture. No sound.

          I tested all the voltages coming out of the power supply...

          Samsung TV`s UE32J5500AK and UE48H6400AK Red Standby Light - No Picture/Sound
          by slimsoul
          Hi, I'm new here and looking for some advice on how to diagnose an issue i have with 2 samsung TVs.

          I have a UE32J5500AK and a UE48H6400AK both with the same issue of red light but nothing happening on the screen, the red light responds to remote or button press by flashing once but stays red. I have searched forums but most turn up a blinking red light.

          I have tried replaceing the power board on the UE32J5500AK last year but this resulted in the same outcome.
          The UE48H6400AK recently developed some small bright areas on the screen, then last week would not power...

          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          ...
