Try these for starters!
Is the power switch broke? Check the power cord! Are any internal fuses blown. Look inside for damage/burnt parts. Are the printed boards broken? after say being dropped? Is the transformer working? Check around the power supply area for faults.
Note - be careful your dealing with mains electric!

How to connect a turntable connected to a yamaha a450 stereo amplifier...can I attache the a450 to the htr-6130 ?


If the turntable is newer kind you can connect it in any Stereo input like CD, VCR , etc.

If the turntable is older model you can only connect it to PHONO input (if amp has one) and make sure earthing cable is connected on Amp

Remember input is only stereo (unless your model has digital input) and select sound effect eg Pro Logic for enhanced sound,

Look closer, it is most likely a component that is called a capacitor and they look like small cans of pop. If they are bulging or have leaks etc, that is the problem.

My amp stopped workin, when i turn the stereo on, the green light is on, then when the music starts to play it turns red and stops working,


The red light on amplifier relates to power supply while the green light is indication of sound functionality. An amplifier that allows sound to generate should display both red and green lights. Howeever, some amplifiers would display only green as long as the sound is functioning.

Solving the problem

First, a red light still on means the power connections to the amplifier is fucntional least requirng repairs.

Second, the green ligh should turn on once the stereo were tuned up to produce sound. If the stereo is still on only least produce sound on the amplifier, check on the connection wires between stereo to amplifier that may have disconnected due to woofing or dubbing sound generals with unfirm wiring.

I have a 70's era Yamaha Natural Sound Stereo Receiver CR-620. It just recently stopped working. It turns on, but doesn't transit sound. Can it be fixed or is it terminal?


If there is no audible physical click from the speaker output relay, after about 10 to 20 seconds, there is an electronic fault in one or both amplifier circuits, which will require repair. If you like the sound of this unit enough to pay maybe $50 give or take, get it repaired. Otherwise, you can pick a similar unit up at a thrift shop for a few dollars.

I have a Yamaha Natural Sound Stereo Receiver RX-750 (purchased maybe around 1992-1993?). The input selector switch doesn't seem to be working properly. No matter which input I select, the sound is fuzzy...


Hi cfipp
You could fix this problem with a quick squirt of CRC 2-26 into the function selector switch connected to the knob you are wriggling. This will sort out the problem. If you need further advice, feel free to ask me. I will help you.
