Sony STR-DE305 Left Channel Cutout Solved -
If it's any help, on the rare occasions that the left channel works I've managed to catch that channel going out and I've noticed that in the few seconds before cutting out there is a decent amount of static in addition to the output on that channel.

However, I have no idea how to trace the circuit from the speaker, and the underside of the board is obstructed by the case. Try to get your hands on a service manual from a service center. These will give you the correct voltages, and instructions on how to replace/repair/test the unit. if you get one in working order, you can play with replacing parts from the good one to your bad one. So here's my predicament: I have a Sony STR-DE305 with an output issue. Most of the time however, the left channel is completely absent. BAD SOLDER CONNECTION OR CRACK ON CIRCUIT BOARD---YES.

I've verified that the speakers and associated wire are not the source of the problem, as well as the toggles for "A" and "B" sets of speakers (I'm also aware that having both toggles activated will yield no output on a given channel unless both sets are connected for that channel). These IC's generate heat during operation and if you notice they don't have heatsinks. Do you hear speaker relays activate and still no sound?

LOOK at the circuit board, inspect the screw holes. I had a sony STRDE90ES that blew a fuse on the left output stage board. Mine is only a matter reset procedures from the service manual. That makes the solder to soften and loose connection.
