The Sound just stopped, power is still on, Tried analog inputs ; no go. I have the main display but also the OSD menu does not come on to the TV, it displays on the RCVR display but have no idea where it is in the menu! tried the TEST for audio channels it is working on the display but no sound. Thought it was a fuse so I opened the cover and checked the obvious ones...there ok!. There is also a fan inside and when the power is on it does not seem to operate. I have not tried it outside the unit yet. Anyone have the schematics for it? Then I would be able to troubleshoot it! Was it just the end of its existence! I sure don't want to take it to Radio Shack @ $500/hour!!! Any assistance will be greatly appreciated!! Thanks
You will need to trouble shoot the audio output amp section. It sounds like the unit is in a shut down or a protection mode. Good Luck

· The OSD Lock Out Message
Power your computer completely off and then remove the monitor cable from the port on the back side of the computer case. Reattach the cable and make sure the pins are correctly screwed in all of the way. Power the computer back on and check to see if the OSD lock out message is still being displayed.

no sound coming from my avr235, although it's lit up like a christmas tree...need help, cheers
I have an AVR335 receiver that lost its sound too. I took it apart to see if any obvious burns or other malfunctions could be seen. Everything looks fine but what I gather is a small thermal protector screwed to the heat sink could be the source of the problem. It has a 2-wire cable that is soldered to the amplifier PCB near the two sets of wires that go to the fans. Does anyone have any info on the sensor and/or how I can test the sensor? I have pictures if they would help.
