Question about Philips MX6050D System
I think this system is ok for a starter - have some speaker crackling issues, the dvd player shows video, but the audio is delayed (I have a different dvd player to use) - the problem I have with the system is the bass speaker channel has stopped working. The speaker works fine, the channel is not sending power (even with that channel's setting turned all the way up!). Can anyone help me decide what to do with the thing?
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.

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.

If the receiver is actually powering up but you are getting no sound, there are few basic things to check.
Check the audio connections on the back (speakers AND inputs) to make sure they are tight at both ends and undamaged. Go into the setup screen for the DVD player and make sure the audio settings are set for PCM output and that you are using a digital or optical audio cable. Then make sure you have the correct function selected on the receiver to match the inputs. If the receiver has a speaker test function, use it to see if there is any output from the speakers. Finally, make sure the volume is turned up and the mute button is off.
Otherwise, the amplifier may be faulty

Turn unit off and unplug, then plug back in and keep finger on eject button, and then hit the power button. Nothing? Get your phillips screwdriver and remove the shell. Then retrieve you disc. While your in there look for signs of a burned capacitor off the ic port chip and take a little glass cleaner and clean the optical lens with a micro fiber cloth.

if you do a search on HTS3450 (same unit) you will find a thread with similar problems. My problem was similar and today I fixed it by changing 2 capacitors in the unit.
