I have a lg home theater LHD657 that shows S-PROTECTION then goes off after afew seconds what could be the problem?
First thing to do is to download the manual and see exactly what the fault indication is.
Only a guess, but I'm thinking S-Protection stands for speaker protection. The speakers are protected by sensing relays and if too high a current is sensed it will turn the unit off. I would check the speakers first to make sure they are connected properly and/or are not shorted. If you have a multimeter, remove the speaker connections, put it on the volts scale and measure the voltage across each speaker pair + & -. They should be all the same (low mV). If they are not then one of your output transistors are faulty.
Sorry probably not much help but good luck as these sort of problems can be hard to track down. Cheers
