Question about LG Audio Players & Recorders
Check all your speaker wiring. Plus make certain the speakers are in good working order, and that low ohm speakers are not connected to it. For example if the unit says 8 Ohm, don't connect 4 to 6 ohm speakers.
If that doesn't solve the problem there's a fault in the main power amp.

Have you connected an extra pair of speakers?. (Thereby loading the amp stage beyond it's capacity)
Are the speakers connected to the unit the original ones the system came with or different? ( Speaker impedance, usually displayed at the back of the speaker cabinet must not be less than amp's specifications....6 ohms, 8 ohms)
If you're driving the unit excessively you're lucky this piece is equipped with protect mode, else your speakers and amp would have been fried by now.
One last possibility comes to mind: High volume causes vibration causing loosely fitted mains plug to rattle in wall socket calling "protect" due to improper feed voltage. Move the unit to another wall socket and ensure a tight fit into mains receptacle.

Ypou have an intermittent problem that sounds to be heat related... the more work the amp does, the more heat generated by the output stages. This will be aggravating some poor solder joints that are cracked or dry. The unit needs some repair work done in these areas. If you have good experience with a soldering iron, the cure for this is to resolder the power stages of the unit, or any other solder joints that look to be failing.

The most common cause is an unsafe load/speaker impedance. If you have the speakers wired correctly, you may have a short in the wiring. If the wiring is OK, the amp is likely defective
Let me know if you have any other questions.
