    I have the same problem, first I noticed that it took the sound awhile to come on and then the speakers began to have a hum or buzz to them, I also noticed that it took the power light on the front to change from red to green and now there is nothing, please help as i tried to get help from Philips and they told me that I just needed to purchase a new system, I guess to Philips are money is just disposable now days.

    Ours did the same thing, specifically with the hum/buzz initially. Now no sound at all, and Philips tells me they have no options for me as far as service. Anyone fixed this problem successfully? I, too, hate the thought of buying an entire new system.

Usaj-
Thanks for the post. This was an easy fix. Mine has been out since Hurricane Rita started the condition. The parts are readily available at the local Radio Shack & most anyone has eyes better than mine to soldier the fix. Just be careful with the three-conductor molex connector is a bit shortchanged on slack when trying to remove/unplug from the Subwoofer chassis. Thanks again & good luck!

As I found somewhere on the internet; 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. Make sure you match the polarity properly when replacing. Your unit will be as good as new and will proibably last forever now.

Can't get sound when playing cd r dvd


If the CD-R/DVD has sound in another computer or player be sure your computer's external speakers are powered and on. Quit the player application that you are using for the DVD. If you are using the computer's internal speakers, or if the external speakers are plugged in and turned on, go to the System Preferences and open the Sound control panel. Be sure that the correct output sources is selected. Open the CD-R/DVD player and see if the sound now works.

Cant get the module to get the so8und bought 2nd had car wiv rosen dvd player a7 in it help]


Hi, The A7 has 3 sound modes. With the unit on press the speaker button and on the screen it will say either "Headphone sound only" or "Speaker sound enabled". Pressing the speaker button will toggle these modes back and forth. If you don't hear any sound when it says "Speaker sound enabled " it may be that it was wired using the FM Modulator, which means it uses the car speakers. For them to work, turn on your radio and tune it to 87.9 or 88.3. Good Luck!

I have brought an lg dvd with woofer and 5 speaker in that 2is working 3is not working pl do the needful


Hi! Can you see 6 RCA jacks at the back of your DVD player(2 red, 2 white, 2 black). And if you don't have these six jacks for sound input then you won't be able to use the 5.1 speaker system with your LG dvd player. Check it in your dvd player manual whether it supports 5.1 speaker system.

Car DVD player will only play sound through wireless headphones, not through speakers


We have a GMC Envoy which also does not allow us to play the sound from the dvd player through the car's speakers. Although we purchased the vehicle new with the dvd player already installed, it was installed by the dealer, making it after-market. I assume those that were installed in the factory work differently. Maybe this is the case with your's as well. Good luck!!

Connect DVD Player to logitech X 540 Surround System


Bad connection on that one speaker, if you have tested the system with other equipment and it works thn you MUST have a bad connection INSIDE you DVD player. If your DVD had a whole channel out on your output amplifier I beleive then 2 speakers would not work so more than likely you have a bad solder joint inside system for DVD output
