Question about Philips HTS3450 System

2 Answers

The equipment began buzzing after powering on. The buzz begins high then slows down to a crawl and then stops; audio works fine after that. We started switching it to an unused audio source instead of powering it off, which worked for a while. Now it does the buzzing whenever we switch between sources, too.

I had same thing happening until it finally died all together. no sound at all.....everything else works.....and sub lights up in standby. i took sub apart today....and found that 2 capacitors had swelled. you can see where i guess they got hot...because of the glue type stuff surrounding them went from yellow to browish -burnt color. so i'm looking for 2 capacitors before i can tell you if its the problem.

    i replaced the two 470uF 25V capacitors in the subwoofer..........with 470uF 35V ones......cause they where all i could find around town....and my sound is back:) the 35V ones are bit bigger but they fit into place for me. hope this helps out someone out there:)

Why does my headset buzz all the time even when I am charging


If it is a constant low-pitched buzzing it is probably mains hum which can be difficult to eliminate.
There are two sorts of mains hum; conducted and radiated. Mains operated audio equipment suffers from this when the power supply smoothing is ineffective or when a hum loop has been inadvertently created. High gain preamplifiers with non-shorting inputs, high impedance peripherals and long leads make equipment more vulnerable.
Even battery powered equipment with a high gain can suffer from mains hum received like low frequency radio waves radiated from nearby mains operated equipment and supply wiring.

My laptop speaker won't stop buzzing. It began


A buzzing/humm sound could be a earth loop problem. This is caused by connecting amp equipment into different mains power outlets.
Use a power board and connect all your amps and laptop to the one power board.

Speaker buzzing at random


It sounds like the socket on your computer is becoming worn or has a loose solder joint.

If you feel comfortable with a fine tipped soldering iron and stripping your computer down I would take a look there first.

Also check the power supply for the speakers to make sure it is not getting too hot.

Kac-8401 buzzing noise


If the buzz is real high pich the faster you go and lowers to a low pich when you slow down then it is you alternator on your engin.
The only way to stop this is to go to an caraudio store and buy a noise filter which will stop the noise. The only bad thing about getting an noise filter is that it will cause the watts on your amp to go down a little bit because the noise filter runs your power source through a box with a step up transformer and a step down transformer. I hope i helped you with your problem

Audio fuzzy or cuts out


Could have a loose connection in the audio section or a problem with the output IC . Also does this happen on the RF input and your A/V inputs or just one of these. If its the A/V inputs only your having this problem check your cables .
