It sounds like the unit was disturbed by a power surge or blackout. Part of the controllers circuit was compromised and out of sync. The parts may be more expensive than a replacement unit.

did you swap the left from speaker with the left front?
if still crackels after that them you have bad left output.

Make sure your receiver is hooked up to proper AM and FM antennae. Try switching to AM, scan stations. If you hear AM static and/or weak signals the problem could be antennas are not hooked up. FM has AFT which blocks out weak or noisey stations and you wont hear anything without ant.

Loose connection or cold solder and cleaning problem this is the main caused of no sound..Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.
Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".
Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....
Good luck:

I have the same problem.It's definitely the pre-amplifier board (board with speaker terminals).I did not quite nail the exact component yet but I replaced with a working one and got back sound output.

time warner does not supply the codes. the equipment manufacturer supplies the code to the remote makers
