Home theatre turns on just fine, but after 10-15 mins a buzz sound comes on and the subwoofer fan comes on and it stays that way! Any advise would be greatly appreciated.

Re: home theatre

I had this same problem. All I did was switch the sound type by repeatedly pressing the "SURR." button on the bottom left corner of the remote. Usually after 10 times the sound is back,

Why does our subwoofer all of a sudden start to buzz when we turn on our stereo/home theatre system on?

Well if it buzzes only for a couple minutes after turn on then it could be when the woofer starts pumping it produces pressure in the cabinet which creates a bonding motion that then closes the cracks, kinda like glue. Like blowing a balloon up in a box. The balloon is the pressure, OR Yes it could be your woofer is going bad. All speakers have voice coils. Tiny wire wrapped around a thin layer of cardboard then attached to the cone. This cone could be getting loose. But when the woofer heats up after a couple minutes it probably bonds the tiny wires so then the vibration or buzzing disappears. Over time woofers can die especially if it produces a lot of distortion, In a speakers life distortion kills and it doesn't matter how much power it can handle or how much money you spent on it.
Not all sub-woofers are alike. Some can handle the really low lows, and some can not. Check your settings too. Over time the vibration of the woofer will start to undo the glue, nails, screws, and even burn through the tiny wires in the voice coil. Oh and make your china crawl across the table... Have you been watching a lot more action movies? Some of the older woofers can't handle the newer digital deep bass frequencies... You may have to reconfigure your setup.

Problem with sound - Philips HTS3455 Home Theatre System

Hi, I am sorry to say that there is probably a fault. First check the fuses if able (a possibilty). If not that then will need to go in for repair.

Hope that helps

Philips HTS3455 max volume very faint music...

This problem seems to have been solved on here for the HTS3450, but the HTS3455 has a different board layout inside the AV Subwoofer. I've replaced two problem capacitors, but still have the same faint audio problem. The subwoofer fan isn't operational either. I'm at a loss as to where to go from here.

Sub woofer its on for 3 sec..

your cooling fan is not engaging and coming on like its suppose to. One, the fan is probably burned out, which sucks because its low voltage and the only thing on the board that is low voltage. Two, there is a thermostat type component that tells the fan to start which HAS burned out and doesnt start the fan accordingly. If you look at the back fan and turn everything on you will see the fan either doesnt start or starts right as the relay trips turning the sound components off. If it starts at all your fans good.The thermostat component will need to be replace and I cant recommend a source. Just trying to explain the problem so you can look for the right repair. Hope it helps. I have one of these and have found this is the problem, but cant find the solution.

Please help with getting 5.1 sound from my TV!

You must run a Digital Optical cable from your PS3 to your reciever. Then press your function button on your recievers remote until you see SAT/CABLE on your recievers display. Next go to your PS3 settings and go to Sound settings, then Audio Output settings, and select Digital out (OPTICAL) then your done. This is the only way to get true digital sound from your PS3 to your reciever.

Onkyo subwoofer not working

I fixed my subwoofer. The resistor at R16 (right next to the fuse) was the fried component. I removed it and replaced it with a 13K ohm 5 watt metal oxide resistor (from Mouser Electronics if not available locally). Works fine now. I got the solution and the circuit schematic from an audio hobbiest at This is, evidently, a fairly common problem.
