LBT-XG100AV stereo. Why is 'push power protect' blinking?

This is a protection warning. There is a problem with the power output. Make sure that all the speaker wires are NOT shorting-out (visual inspection). You can test the cables with a multi-tester set at the 20 ohms scale, by unplugging from the amp and testing each cable pair at the terminal. They should read anywhere between 4 and 10 ohms resistance (resistance close to 0 indicates a short)..
If the Speakers/cables are good then you have a burned power output stage or a cold solder joint at the fault sensor circuit.

I have the same unit, although it's a bit old now. I used to get that problem, and the protection system is to protect the unit from over-heating, and the main cause is its because the unit is getting hot and/or there isn't enough air going through the rear of the unit. I found a fan or better air flow helps.

the ic was burned out it happens when you put the volume too loud for a long time.

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.

Always be the audio amplifier IC fried need to be replaced

Maybe the audio amplifier IC damaged and need to be replaced good luck

My Sony audio set keeps saying push power protect and the set freezes what should i do? Please help me solve this problem.

How do I remove the protect mode from my Sony LBT-LX5 Stereo?

Power protect tends to mean the main power amp chip has "blown" and needs to be replaced. It only costs about 20 dollars (10GBP). If you are handy with a soldering iron it is easy to do (after you get the thing to bits !) It is the big black thing on the big heatsink inside. The Sony part number is STK442 - 130. Seems a waste to throw the whole thing away for the sake of 10 pounds !. Hope this helps. Nik Howell ([email protected])

Sounds like your protection circuit has been activated, which usually means that you have some blown output transistors. Good luck.
