    Samsung ps43d490 no picture.

    Hi all,

    Recently my samsung plasma 3D TV started playing up, after turning it on the screen will turn off (completely black) but the sound continues to work, this can last anywhere from 10 seconds to 30 mins but the picture eventually comes back. I've tried different output cables and it happens on ALL outputs (sky, DVD, PS4 etc) I've plugged it into a different socket, unplugged it over night, done all the updates, I've tested the fuses on the boards and they all read fine and I've tested the power supply cables and they all read normal, none of the capacitors look blown or swollen and there is not scorch or burn marks on any of the boards.

    I'm at a loss for what to try next, I don't really want to spend money replacing one of the boards to find out that it wasn't the culprit.

    Hope someone can help!

    Thanks in advance!

    Haley.

    check for dry soldier joints.

    its seems intermittent to me and could be dry solder joints.

    Not sure if plasma's have tab bond issues, I would look into that.

      Thanks for the suggestions! All the solder points look fine, nothing loose. :-(
