My Sony home theater DZ290K had a push power protection on the display screen how can I fix it?


The "PROTECT" and "PUSH POWER" messages will flash alternately when the protective device of the amplifier has been activated because a strong signal was input, or if there is a short-circuit detected. Press the POWER button on the unit to turn off the system, and check the following items after "STANDBY" disappears.

1) Are the + and - speaker cords short-circuited?
2) Are you using only the specified speakers?.
3) Is anything blocking the ventilation holes of the system?

You may also refer to the following link for additional troubleshooting steps.

My stereo says" protect" everytime i turn it on. can't get anything else.


Hello grammagrisbo, hi your Kenwood head units will show "protect" when there's a problem with the speaker outputs so check to see if the impedance load meets your radio, 8ohms or 4 ohms?. having parallel two speakers on a single channel may cause this dilemma. This might also mean a shorted speaker wire, a blown speaker, or an internal defect in the head unit. Once the condition that's causing the "protect" mode is fixed, the CD player should be back to normal, the next time you turn it on.
If it's staying in "protect", then you'll definitely have to remove the stereo and do something to fix it. Many car audio stores will do system troubleshooting, for a fee. If you want to do it yourself, here's what you need to do:

Pull the Kenwood unit from the dash and disconnect all the speaker wires. power it on and see if the "protect" message displays. If it does, the stereo has an internal defect and will need to be serviced. If it doesn't, then turn it off, and re-connect one speaker only. Turn it on again and see if it will displays "protect" message.

If the radio works with one speaker connected, connect the other speaker to the second channel, you may have now the idea where the problem begun, you will identify the speaker that's causing the problem. There may be a wiring problem or defective speaker in that channel.

If it displays "protect" with a single speaker connected, then disconnect that one and try the other one. If all the speakers cause a "protect" mode, then you're probably back to a defective head unit.

KENWOOD DECK FLASHING (PROTECT)


protect mode means some speaker wires somewhere in the car are grounded out or are crossed... find the short and it will fix the problem. try testing all of the speakers one by one from the wiring harness... you'll find the problem. Good luck.

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.

Security Code for Protect mode


Turn on the car so the radio is flashing "Protect." Look on the front / removable face of the stereo. On it you will find a small round hole - that's a reset button. Find a small paper clip, unfold the clip and stick it gently into the hole. The "Protect" will stop flashing, and Kenwood will be displayed. Unfortunately all your settings/presets will be gone, but at least the stereo is working again!

Protection displayed and shuts off


The protect message indicates that the output amp section has a problem. Normally this requires the replacement of the output transistors or the output amp pac. Expect the repair cost to be about $20-$60 for parts plus the local labor rate.
