Hi there I have a C340 that has similar problem, you must have bought this from ebay, lol.
Nad made a mistake on the C range, the pre - power link can be shorted out. if the pre is shorted out it takes out the pre amplifier stage, I have managed to get the right channel working, I will keep you informed what is the cause of the left channel. I have replaced the pre-amp IC and a couple of Jfets and transistors. Once I have repaired the Amp I could repaire yours if you like???
Hello Disconnect all speakers and switch ON the set without any input connected, and see whether it heats up. A moderate heat is permissable, but should not over heat. If it overheats without any load or input connected, the set need service. OK.
Just came accross your post accidentically, while reparing my own C320BEE. May be it 's too late for you now, but it could help others: I had the very same symptoms as you described and after a long search found out that the trouble was R45 in one of the 18V regulators. (R45: 33 ohms 1/2W fuse resistor, situated more or less half-way between the two "metal towers" on the main board. Replace by a somewhat stronger type 1W or so.
