    I have an Optimum 3570 receiver. Yesterday the sound from my speakers went very faint. I turned the volume all the way up and I can barely hear the radio, or the Record player. How do I trouble shoot it?

I am connecting an older receiver (amp) to my DVR

Did you try the DVR through the same input you're using for the DVD to see if it's related to the source or the input on the receiver? BTW: don't use the phono conenctors for anything but a turntable.

Right speaker goes off when using Rec out on the Phono input

The switch is contaminated. Pick up some electronic switch cleaner and spray into the switch. Move the switch back and forth a number of times and that should clear up the problem. Make sure that you get the cleaner that has a lubricant included.

Yamaha Receiver R-700 Input & Recout switches cut out!

I have 2 of the same receivers. One works perfect and the other had the same problem as you describe. The faulty one I brought to work to use. Since I wasn't planning on recording anything I desoldered both swithces and swapped them. The REC OUT switch is a 6 pos SW, and the INPUT is only a 5 pos SW, but it works. Now my sound doesn't cut out any more and I have a receiver for work.
