It sounds like you are describing an earth loop problem. I won't go into detail in this post, but try an isolation test first. disconnect everything from the reciever except the sub and try connecting say a BATTERY powered mp3 player or cd player to minimise connections to the electrical mains earth. you could also isolate things by taking your sub to a friend's house and trying it on their system. If it is an earth loop use a process of elimination to find out which two pieces of equipment causes the earth loop. then apply filtering. you can buy earth loop isolation transformers for about AU$26 and I've used one on my sub myself. Theyhave RCA (phono)plugs on each end and they connect inline with the signal cable to the sub amp.
as for the thumping sound it might be the speaker protection circuitry cutting off the amp to protect the subwoofer speaker from damaged. This might be triggered if the earth loop sound is causing the sub amp to overload and clip.
Failing this there might be a dried out overheated electro capacitor in the amp circuit causing the hum. Hav a chat to your local electronics person, who should be able to spot it! Hope this puts you on the right track Happy Hunting!
i experienced that problem before.one cause is the cd itself.there cd's that are too thick so the motor has hard time rotating that makes vibrating sound.the other ,don't put something over your unit.the cover is touching the holder of the cd and makes a sound.just do the necessary things to be done like don't put something on top your unit.if not, then a manual analysis of the tech is the last option.
It sounds like the tapes may be physically damaged, wrinkled or creased. This may have been done when they were played in whatever machine you used 5 years ago. Tapes can also be damaged in storage by heat or humidity. Tapes should also be stored on end in their boxes, not flat. If these tapes were stored flat, the bottom edge might have gotten wrinkled. This can damage the control track and cause playback issues.
Does the DVD player still work, even though it's making the humming noise? The humming noise may just be normal for that machine. Turn your TV up louder . If the player doesn't work, the drive is broken, and you would have to send it to Phillips if your warranty is still working. If the Player still works, check to see if the disc is warped or cracked, this'll make the drive unstable, and make the noise.
