Question about Bang and Olufsen Beocenter 9300 Shelf System
No matter what your running thru the receiver there is no sound out of the 2 left side speakers, only the right side. Am I missing something or is the unit broken? Everything is hooked up correctly and I know that the other items all work. What could the possible problem be and what might be the solution?
If you connect a pair of sp to sp2 outputs only and the l/h is dead check balance on mcp5000 it may be over to the right.

Tips for a great answer:
Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Eure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
