My HT-D355K is displaying protection in the screen what should I do please help.

SOURCE: powering off for protection samsung HT-WX70

the fan is broken on your unit, this is a feature to keep the unit from over heating

check if there is anything blocking the fan from moving/rotating

try to contact your manufacturer

You probably have the same problem that myself and several others have had, and let me guess, its outside of the warranty? How good are you with a soldering iron? If you are not afraid to do some soldering you can fix it, check out these instructions that i found:

you will need 474k or .47uf 100v capacitors and a soldering iron, but you can fix it, worked for me.

The amplifier has a bad channel, or is bad itself. It is trying to either output too much current or is not putting out enough. If you have multiple speakers wired to one channel, you will either have to change the wiring to series(unit positive to first speaker red, first red to second BLACK, second red to unit negative) or remove on speaker. (If this is the case, then you might want to look at this. It is a tip/rick to place and properly/successfully run three subwoofers, but the main concept can be used on all channels.) If all channels are wired to he correct speaker, then the amp is in fact at fault.

The amplifier has a bad channel or is bad in general, and will need replacing. In some cases, it's a separate board and can be replaced itself, but in others, everything is on one board(except the power supply unit) and warrants just having he unit replaced.

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be with your output drivers. Please check for short on the outputs fitted for both the channels. Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise which can be a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board. Maybe the protect circuit by itself is shutting off due to a faulty bias or there is a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the amplifier comes out of the protect mode then check for short on the speakers.
