Panasonic TU-PT700U - 9 Self-Check Function; Self-Check of the Microcomputer Control System (Bus Line)

9 Self-check Function
When symptoms like “the power fails sometimes” or “sometimes there is no picture and/or sound” can not be confirmed at the
time of servicing, the self-check function can be used to confirm the occurrence and to find the defective circuit.
In case of “power failure”, flashing of the “POWER” indication (red) at the front of the unit can be used to narrow down the +B
line.
