    Samsung PN50A450 "Not Available" Problem

    Hello Everyone,

    I stumbled upon this site while trying to find repair info on my TV. What a cool place!

    My TV started acting odd yesterday. It doesn't respond to the remote, but it does power on with the button on the TV. Once it's on, I do get a picture, but an error message pops up that says "Not Available." I'm unable to do anything to remove the box. I can hit the menu button on the TV but it returns to the "Not Available" error message instantly. It's almost like there is a stuck button repeatedly triggering the error. I've removed the batteries from the remote, but that didn't help. I tried entering the service menu, but since the TV doesn't respond to the remote, I don't think that will work.

    I'm not sure what could have caused this. Do I need to change out one of the boards? I found a few replacement boards on eBay, but I'm not sure which board to try first. Thanks for any help!

    Open the TV and unplug the the remote sensor from the main av board, then power on the TV using the buttons.

    If the problem remains, unplug the buttons board and turn the TV on with the remote.

    If the problem Still remains, you could replace the main av board.

      Hamie, Thanks for the suggestion. On my set it looks like the IR sensor board connects to the button board. I disconnected the IR sensor from the button board and the error message is gone

      Now I'll need to figure out how to get the remote working again. Does it make since to replace the IR sensor board? The problem could be upstream, but that doesn't seem likely since removing this board cleared up the error message. Has anyone seen these sensors go bad out of the blue?

      Here are pictures of the sensor board. I did find some for sale on ebay.

        Hey Hamie, I ordered a replacement for the IR sensor board on eBay for $10. I put the new board in and everything is working great now. Thanks again for your help!
