Hello Everyone,
The knowledge I gained in 2 semesters of physic is the extent of my knowledge of electronics. This naivety is no excuse for my foolish decision to connect a 3 ohm subwoofer to a receiver that is rated for 8 ohm speakers.
After cranking the volume up, the receiver shut down. Any attempts to turn it back on result in the system shutting down about 10 seconds later and electrical smoke (if that is even what it is referred to as). I notice that the source of the smoke is a resistor that is labeled as R202.
Before I send it in for a replacement ($50), I figure this could be an opportunity to learn how to diagnose and fix this problem. So my questions are:
1) How can I diagnose the root of the problem?
2) Can you provide any databases or websites that may help educate me?
3) Based on my scenario, what damage is likely to have occurred?
4) How can I fix this problem (or what websites should I go to to learn how to fix this problem)?
