    Samsung PS50B451B2W - mal discharge and sky HD box HDCP not supported

    Hi all

    got this in part ex, has mal discharge iv tried increasing the VS +5% didnt seem to make much difference anything else i can try ?

    also the main fault was the user was unable to get anything to display on HDMI or scart all he could use was freeview

    I didnt even check just did factory reset and check firmware upto date and then tested

    My ouya box works fine so does my xbox 360 but when i connect it to sky i get
    This display does not support HDCP message, this is the same even after i set the sky box manually to 720

    I have tried updating the skybox also i have turned them on in order ( re set all ) tv on to correct HDMI and then skybox

    still getting the message

    Im going to try a youview box to see if that works

    if it does i guess i will have to sell describing it wont work with sky which will put alot of peeps off, iv read about the keys but does that only effect sky why do all the other devices still work on it ?

    After more reading about it, seems I will have to replace the main board to resolve the sky tv not working but can I just increase the adjustments on y and x main to try resolve the sparkles and ghosting?

      Try altering slightly, the Yrr and Yfr controls on the Y-SUS. Mark the pots first though....

      Also, Lower the Vs by 5V from that indicated on the panel sticker, check and set Va to specified value.
      Worth checking the other voltages are as specified too....
