Question about Philips HTS3450 System
I have had this thing for less than a year and it worked great up until about a month ago, now the dvd player still shows the picture, but there is no sound coming from any of the speakers including the sub. i called phillips and they will not fix it under warranty because i lost my receipt. i dont know of any ways to fix it or what i should do. i have checked and rechecked all connections. any help would be very helpful
There are two 470uF/25V capacitors on the power supply board in the sub-woofer that are the cause of buzzing, crackling and then eventually no sound. Go to Radio Shack and buy two Catalog #272-1030 470uF/35V capacitors and change them out. They are in the middle of the Power Supply PCB and are close to the long flat aluminum heatsink. As far as installation instructions go; you have to have some soldering experience, first. You will also need some type of de-soldering device, be it a solder ****** or solder wick to remove the caps. Make note of the polarity before removing. Then it is just a matter of popping the new ones in (they are slightly larger than the originals so they might not go all the way down flush with the PCB) and soldering them back in. Make sure you do not make any solder shorts or your system will be toast! Your unit will be as good as new and will probably last forever now.

I had the same problem except my volume would just decrease after a few minutes of being on like someone was pressing the volume down buttton. If I walked over to the subwoofer and gave it a knock on the top the volume would instantly come back on where I had it set before. I took WheatService's advice and replaced the 470uF/25Vcapacitors and everything is working great now. I am very pleased. BTW, the parts at radio shack were like $3.00. I needed a desoldering tool, which I would recommend for this job...the one with the suction ball. I also needed some more soldering wire for a total repair cost of about $17. If you have all the tools the capacitors will cost you $3.00. Philips wanted to send me a replacement unit for $100.00 and I'm sure the local repair shop would have been the same if not more. Thanks again, WheatService!

Follow WheatService's instructions for repair. I repaired my unit having the same symptoms as other posts here and it works like a charm... for under 5$!!! I will never buy another Phillips unit again, but thanks to the helpful information here, I won't have to run out and buy another system for a while.

Same problem here. I've had it for less than a year too. I was unplugging the jack that goes from the sub to the dvd player multiple times until I heard sound and that worked for about a month, but now there is no sound and shows no sign of ever producing sound again. system sucks...
