    I have the Philips HTS3450 DVD home theater system. I have had it for over a year now, and love it, except.... In the past couple of moths we recently moved. After hooking up the system exactly like it was premove, I get a clicking sound that starts out spaced apart, and progressivly gets closer, and closer, until it becomes one high pitched sound from all my speakers. It reminds me of some kinda of warming up sequance. It started out rather quickly, and over the past few months has gotten longer and slower. There is no sound until it goes through this routine. once its done, all is well, until.... Today, no clicking, no progression to a high pitch union. Nothing. So now I have no sound what so ever. I have double, and tripled checked all connections. Recycled the power several times. Double and tripled checked all settings too. I do not know what could be wrong....

    Bought the Philips HTS3450 about a year ago. A couple months ago it started "buzzing" on startup...a few seconds at first, then the buzzing got progressively longer and longer. Today it went for over 20 minutes before I finally got tired of it and unplugged it from the TV. So now I have the sound from the TV alone. I miss the home theater sound, but apparently these things are pieces of **** that work for a year and poop out on you.

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.

WheatService's advise worked. It wasn't hard at all. I pulled out the bad capacitors with plires. Then I put the new ones in and soldered them in from the back.

Obviously something is wrong with circuits. Have it checked by pro/tech

Sounds like unit is in protect mode. This is usually caused by a problem in the amplifier section. Only way to fix is to replace the main board - hope it's under warranty, otherwise it's probably not worth fixing

Unit intermittently makes the TV flicker the sound and picture.


I would be checking and trying new leads from the antenna part of your telly to where they go into the wall , we had a problem with a new tv that used to turn itself off and on we got the tv replaced with another new one and it still did it . it turned out to be a faulty cable from the pay tv box on top of the telly as they emit FM waves just like the radio and it was sending signals to the remote on the tv to turn it off

RT2760, sound behind picture


It may be that your audio cables are poor quality. Try getting some higher quality cables to run your sound and see if that helps. If your system has optic outlets then these are best. Coax are better than RCA as well. If only RCA, then just try buying some higher quality RCA cables. Good luck!

Maybe the speakers are no good. Have you tried hooking up a different set of speakers?
