While playing my unit we had a brief power outage. When the power supply returned the " PROTECT PUSH POWER " message comes on. Is there a button that I can push to reset my unit-LBT-X50 .


Hi,
Your sound system may have a circuit breaker.
Check the rear of the sound system for a circuit breaker that has popped out, Then push it back in.
It may be labelled.
  • circuit breaker
  • protect push power
Otherwise unplug your unit from the wall and wait 5min before you plug it back in, then press the power button on the front of your system and your remote control.

I hope this helps

Please help me i have a problem with my hifi .i got the message protect push power


This indicates a load problem in the system, turn power off! remove all speakers and wires, now turn the receiver on "this will reset the safety circuits" and turn the volume right down, If the word protect stays off it means there is a short in the speaker wires or one of the speakers. Now if the word protect comes on when you turn the receiver on "with all wires and speakers dis-connected" then it proves one or more of the audio output ic's are shorted, this is where a technician will be needed to further assess the situation.

HiFi system goes to standby because protection circuit detects error in amplifier section, you need to take unit to qualified tech for fix.
