Question about Sony HT-5100D System
FIrst a couple of questions about the symptom:
1) Does the sound start out at the correct level and then drop off or is it always low?
2) If the sound level fluctuates, is there a pattern to when this occurs? Starts out OK, fails after a few hours? Starts out low, ends up OK after a while?
3) Do other inputs work OK with the receiver?
4) Is the output from the TV a "fixed" output or variable? (this should be marked at the output jacks.)
I'll look up the model in the meantime, but please respond to the above as it will make diagnosis much easier.

Follow first all the indications provided by Ekse, probably you will fix it following the procedure in his post, this will make things much easier.
Also ensure that you checked speakers and cables properly.
If it is the home theater can be a lot of things, you need to put your hands on it.
You check most stupid first, like the touch buttons , when they are faulty sometimes the volume goes suddenly down like if you press the button.
If the volume instead cut off suddenly then you may have a problem with the amp, you need to follow the diagrams in service manual, as suggested and test the board, even a condenser gone can give you this kind of troubles.
In service manual you will find diagrams indicating which zone of the board (control, amp. preamp) you have to check when you have problems with sound going down or cutting off.
