I purchased a used Yamaha RX-V660 Receiver several years ago. Seems the right channel doesn't have sound. It's been on a stand, not used in a few years. Can it be repaired? Is it worth being repaired. Any feedback would be great.

Yes, this receiver is a good one. Alot of gear from a few years ago will still outperform new gear. And why change something if it can be repaired. It most probably has a blown backlamp to the lcd display...some models so easy to change that they just plug in!!. This is quite common and easily fixed. Heat kills electronics. If you wish to keep the old girl going i suggest trying to increase the ventilation. even by getting it into the coolest place in the cabinet. The top of the rack of gear is always best for your amp to get rid of the heat. and try to put some extra height(with say a 2 sticks of wood) under the feet both under the amp and any bits of gear that may sit on top while taking care to to block the ventilation holes. if the amp uses a rotary function selector switch it may have dirty contacts that are causing your crackling problems. A spray internally to the switches contacts with CRC 2-26 will sort that.
Transmitting doesn't mean it's working, What you should do to test it is use a good quality universal remote such as a Logitech Harmony and first program the preset code for your receiver into the Universal Remote. If that works, you know your OEM remote has gone bad, at least for those buttons. If it doesn't then you you should attempt to have your Universal Remote "learn" the IR signals from your receiver's remote If the controls still don't work, there is a problem with either your IR receiver on your receiver or the the circuitry that proceesses the signals into commands.
The right or left (side) output channel has blown out. If it uses discrete transistors you'll have to replace two of them (one PNP and one NPN) along with several resistors that are part of the circuit (I'm guessing the static occurs on any input source). Now , if the static happens only on certain input, then the problem should not be in your amp.
Hi Zanthena - my Yamaha rx v 2200 is doing exactly the same thing - did you manage to track the problem down? I have had my unit in for repair and the fault occurred again 6 hours after I re-installed it.
