I have a pair of Infinity Beta 50s hooked to a Denon AVR 4802, and all of a sudden the left speaker stopped working. I checked all speaker connections and replaced the Monster speaker wire with no success. The right speaker, sub woofer, center channel, and two rear speakers all work.
There was no loud sound or any type of distortion or any indication that something blew. It is not making any sound at all.
The speakers are about 5 years old, and the 4802 is about 7 years old. I believe Christmas music was playing at the time, so the volume was not high.
Any ideas?

Page 10. The S-302 uses a proprietary D-Sub25 system cable to the DSW-S302 subwoofer. Don't know if or why it has more than 2 active conductors. The other speakers have removable cable ends so they might work just fine.
you need to find a headphones, put a drop of contact cleaner on headphone plug and plug it into receiver's h/p input several times. It cleanes internal h/p connector contacts and unit will work fine. If doen't help the receiver most likely has bad h/p connector soldering.
Not familiar with this model but seems like the protection circuit is kicking in, this could be caused by an imbalance of Ohms between channels or a short. remove & check all speakers and cables for continuity or shorts, does the unit power on without speakers or in a different mode (surround off).
always add speakers in pairs (L&R) before testing to prevent possible protection circuit, test main speaker pair first then add surrounds (all according to the allowable Ohms range for the amp of course)
I guess you could try y cable adapters for input on the Denon. Might get messy. Try radio shack and pick up 5 y cables for the speakers and 1 for the sub. Someone probably makes an audio switcher that handles that as well.
no the problem is at the plasma you will have to change the setting back to the scale range that will accept the signals from the Denon, see Plasma's manual for instructions
