    Sanyo DP50749 Sound no Picture

    Ok so my first issue was that when you went to turn it on it just click on then off over and over again. So I bought a Main Board as I was told that is the issue at that point.

    Now the new issue is it will turn on and there is sound and the remote works but no picture. Can anyone help me out on what the new problem may be. Also when you first turn it on it shows what input you are on then fades away within a couple seconds. As if the screen tries to light up for a couple seconds.

          50 views and no answer or an idea at all?

          How about a new question is there a chance that the main board I purchased will not work with the Panasonic equipment in my TV?
          Is there a chance it is still the main board at all?
          Could the master and slave boards went bad as well?

          Anything would be appreciated.

              T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
              by Tr0ll
              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 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              ...

              Anthem MRX500 - no sound. R2A15218FP issue??

              Anthem MRX500 - no sound

              Dear Electronics Experts:

              I have the following problem I am trying to troubleshoot. Unfortunately, I have contacted Anthem themselves and even a local distributer but I am not having much luck. Also, I have scoured the internet and unable to obtain a service manual. The Anthem service rep has also replied that he is unable to provide me with any service documentation. I have performed numerous searches on the internet and cross-referenced a few other AV receiver makers (Denon, Marantz, Onkyo) and found certain similarities to block diagram...

              Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
              by Ierwin
              Hello everyone,
              Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
              The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
              He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
              I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
              Anyway I still fully expect that there has been something seriously damaged...
