Y-sustain boards are found in plasma TVs and drive all of the Y-axis video signals coming from the logic board to your TV screen.
• If your TV has has no video, then the Y-sustain could be bad.
• If your TV doesn’t turn on, then the Y-sustain could be bad.
*These are helpful tips to get you started and don’t represent accurate diagnoses for every TV model and failure. If you’re unsure of your diagnosis, we recommend checking out our YouTube channel or reaching out to a local TV technician for assistance.
While replacing the Y-sustain board is pretty easy, you’ll want to be mindful not to tear the flat ribbon cables when connecting/disconnecting the board.
