Likely a problem with the amp. Buy a new one and don't run it on full power for too long. Mine got shagged when I had a party and maxed it out for 2 hours.

Read it could be excessive solder on the amp circuit heating up too much then obviously not working after it cools since the connection is messed up when the solder changes shape.

Hey i have a sony lbt-xgr90av and when i turn it on it comes up with push power protect i just want to no if there is a reset code???


NO, the condition causing it must be resolved as it is a designed-in safety feature.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

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

Resolve the cause.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

You PUSH the POWER button to turn it OFF. It's sick.

It comes on and goes back off, and is asking me to push power pro


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

Sony LBT W5000


According to Page 46 of the LBT-W5000 Operating Instructions:
"The display stars flashing as soon as you plug in the power cord even though you haven't turned on the system (demonstration mode).
Press DISPLAY (for LBT-W5000 / W300 / XB700 / XB500) or DEMO (STANDBY) (for other models) while the system is off. If the system is in the Power Saving mode, press POWER SAVE / DEMO (STANDBY) (for LBT-W5000 / W300 / XB700 / XB500). The demonstration appears automatically the first time you plug in the power cord, or if there is a power outage lasting longer than half a day."
I tested this today, as my LBT-W5000 was in Demonstration Mode. It definitely works. The only catch is (at least on the W5000), and it's a minor one, you have to reset your clock afterwards.
