    Samsung Plasma sound, but no picture

    Hey folks,

    Just found out about this forum and I'm hoping I can find some help. I have a Samsung SN60E530A3F plasma which has had power up issues for a while now. It started taking one or two times trying to power it on to get picture. When this occurred, it has sound but no picture at all. After several attempts the picture would finally come on and it worked flawlessly until we turned it off again. Well, as time has gone on (about 6 months now) it has taken more and more attempts to get it to come on, until now where I cant get picture even trying 30 plus times.

    As a novice at electronics, I found all the information online pointing toward bad caps so I replaced the ones on the power board, but that didn't fix the problem. Assuming it was still an issue with the power board, I replaced it with a refurbished one I bought online. Same results, so I returned that board and put the original board with the new capacitors back on.

    At this point I decided to try checking voltages at the power board with my multi meter, Vs was supposed to be 211volts. By the time I turned it on, and got the multimeter on the test point it read 192 and was quickly dropping, eventually reaching 10.5 volts after about a minute.

    A YouTube video recommended unplugging the x and y sustain boards and trying again, but when I do this the tv wont power up...not sure why.

    Any tips or further guidance is much appreciated.

    Usually no picture but audio is the Ysus. But it usually goes pop and that's it. I find it odd that it would work intermittently.

      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

      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...

      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...

      Samsung Plasma PN43E450A1F - No Picture / Pop Sound
      by willis6732
      The customer of this TV Heard a pop sound before it went dead.

      The VS and VA voltages turn on imediatly and then slowly die off.

      I got a replacement Y-Board (Large board on the left) from aliexpress and still no luck

      If tested all the IC chipson the board all the way on the left by running meter along the connectors and couldnt find any shorts there...

      I think ive checked most the capacitors for shorts as well as most of the diodes and mosfet/transistors on the big boards.
