Question about LG F-185 CD Shelf System
First make sure that the speaker wires haven't fallen out of the wonderful spring clip connections the factorys use. If they are hooked up properly and you have a headphone jack plug in a set of headphones and check for sound. If you have sound the problem is in the power amp. If not it could be in the preamp or power amp. At this point if sound is absent and you can solder, open the unit and check the solder joints for bad connections and resolder anythhing which looks questionable. These days the majority of problems are related to cold solder joints. If the unit still is not working you will need an O Scope to trace the signal. If this is beyond your capabilities any repair shop should be able to find the problem.
