Question about Sony STR-DH800

1 Answer

After only 5 minutes of turning it on, My Sony STRDH800 emits a loud hum, then the word "protect" is displayed on the screen, then it shuts off. The hum is very loud and you can't turn it down with the volume control. You either have to shut off manually or wait for it to protect and auto shut off. I read here someone has the same problem. Where do I find the main power supply filter capacitor? Thank you

Are you sure that's what it is? Something is heating up for sure.

It could be protecting itself because something in the volume control is going bad and sending too much current through the amp or any other reason. In other words, you can guess and buy parts hoping to nail the symptom but not knowing the cause, or you could let a technician do it.

Sony STRDH800 emits a loud humming noise cuming throu speakers as soon i switched on and after 3 minuts av reciver switched off byself and blinking protected......plz help


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 your output drivers- the MOSFETS/IC's 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 like 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 , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

Very loud hummimg and crackling - even when volume turned down.


There are a few variants for this model depending upon the serial number. From your description, there are some capacitors in between the amp stages called coupling caps that are failing. The hum is some DC current being passed through the output stage. The crackling is probably just dirty controls.

Let me know if this helps.

I can't say exactly which one you need to change and don't worry about messing anything up, you can always just change them back.

Let me know which one fixes your problem.

Best of luck!

The power fuse blows as soon as the unit is plugged in


There is a problem with the amplifier within the sub. Many of these units never completely turn off. They are often set to automatically startup when a signal is detected. This may be the case here. The loud hum as a defect in the output amp section. At this point you probably have a blown amp section. The "protection" for this is to cause a dead short that will open up the fuse. This unit will require service. It is unlikely that any service info is availabel to the general public either.

The fix could be simple, but without seeing the unit, I can not state that for sure.

Keep us posted.
