Power Down – Quick Troubleshooting Tip
Plasma Panel shuts down immediately
After power on.
First unplug the two connectors on the SMPS
Assembly (the connectors with all brown wires).
Next unplug the TMDS connector from the
Display to the panel assembly (silver shielded
connector).
Try to power the set on in this condition. If the
power stays on you will need to troubleshoot the
Panel assembly PCB’s. If the power still shuts
down you need to troubleshoot the Display, DTT,
SMPS Audio or Thermal sensor assemblies.
