Check mute is in off position. If problem persists, the check plus minus 5V supply section and measure voltages at IC30.
Here is service manual for help.
You would need the digital optical cable out from the television to a digital optical cable input on the DV-C200 system. Digital is not like a normal signal in the way that analogue AM radio and FM digital radio differ. In fact it is more like DAB radio.
The best thing to do it Google the manual for the television and the speaker system and read the input and output specs.
You may need a professional cleaning of all the switches internally. If you are up to it. Compressed air with an electronic aerosol cleaning solution is the first approach. Over time these parts develop oxidation. The voltage levels are small and the signal cannot be generated.You need to know what too clean, most are visible. You can also look for internal fuse protection. Make sure when the cover is removed to pull the power first. Some higher end Amplifiers provide protection. You will need a digital multi-meter or equivalent to test the fuses.
So before doing all of that. There is a reset switch. It is located between the speaker switches on the face of the receiver. At the top and in the middle left center of the display. Not at the speaker buttons on the left.
That function may be tripped. Reset it twice and try testing with different speakers if it fails again. It may trip instantaneously if there are abnormal voltage levels present in the circuit that arouse protection.
I have located and offer you the Manual PDF. Go here first and try the following. On page 8 in the manual. Titled, " Name of each Control" (D). There is a location diagram for you to observe. Please take some time and look this over.
If you've already swapped them left to right to prove the speaker works bt the channel doesn't then you know the problem is in the electronics. Is it one or more sources? Turn the receiver off and manually operate all the switches and knobs throughtout their ranges (particularly the Tape controls) and see if that helps. No? Take it to someone to look at it.
This is a good indication that the amp is geneating too much heat. There are protection circuits inside that will shutdown the amp if it gets too hot. You will need to determine what is causing the excessive load on the amp to make it generate that heat. Look for crossed wires or problems in the speakers. This amp is designed for 4 ohms (I think) and a load less than that will still work, but cause the amp to work harder and generate excessive heat.
Funny you asked! I just got this receiver today, and its the first problem i had. Its the speaker wiring quality. I had thicker better quality wires in center channel speaker and audio was fine. Cheaper thinner on front and kept cutting out on 3 or 4 voulume level. I switched wires just to test and it never cut out again. Audio was fine.Try better thicker wires and u should b alright.
