Subject: Inverter unit shutdown.
Symptom: The screws securing the inverter unit loosen and the ground becomes intermittent
causing no or intermittent backlight.
Solution: Replace the six screws that mount the inverter. Do not reuse the removed screws.
New parts #LX-BZ2315TPZZ This is one option. You can also move down the inverter board and make sure each black square is pushed down firmly. Very easy for these to pop loose and give you a shut down. If this does fix it, you will still need to force the backlights on and do a factory reset, or you will keep shutting down. Good luck to you.
