Re: volume

If the volume control does nothing them spraying it will do nothing. If it is noisy when you turn it but the volume does change them you can try to spray it with cleaner. You cannot do this from the front; only from the inside and only if the volume control is not sealed.

Pioneer vsx1021k volume drops by itself at 3db increments until there is no volume. M volume is displayed when this happens as if someone was manually turning the volume knob.

Dirty rotary encoder (volume control ). If you are confident with opening the unit yourself, a spray of contact cleaner into the encoder might help. Ideally u should replace it.
The volume minus button on your remote is dirty/shorted. Try removing remote control batteries and see if the issue disappears.

How to fix old 1970s receiver Loss of volume or sound to one channel

volume control is like a rheostat and has a tendency to corrode over time. try working the control vigorously back and forth numerous times. if this fails, carefully remove receiver cover and use electrical contact cleaner (comes in a spray can). if this fails, you'll probably have to hunt down a new one.

Left channel cuts out, if i tap the reciever it will come back on.

sounds like the controls are dirty...or possibly the solder connection on the volume control has become can goto your local electronics store(or Radio Shack) and get some contact the unit up and clean the volume control as per the instructions on the can...make sure when you spray the cleaner into the control you turn it back and forth several times...then you want to spray more in to flush out whatever debris may have been in careful not to get any on the face plate as it may damage the finish...also , make sure that the chemical spray that you use is safe for plastics...If this doesn't fix it , then the volume control assembly may need to be resoldered.

I have a pioneer vsx-d704s reciever and when it is at a very low to 0 volume i get a low level scratching only on the left side. im not sure if it goes away when i turn it up or not but i dont think so

The volume knob is dirty. Behind the face of receiver the "pot", (as they are called) needs sprayed with contact cleaner. I use CRC QD contact cleaner. If the volume is a slider your can use the straw type devise for pin point spraying in the slider slot with receiver off and unplugged. After spraying work the slider back and forth to distribute the cleaner inside. If you have to remove the cover for a rotary "pot"spray while working the dial. Hope that helps..

The volume knob doesn't work properly, with both directions turning the volume up (or both turning it down).

The volume control assembly probably has dirt/dust built up can clean the control with an electrical contact cleaner that is safe on plastics (ask your retailer ). You will need to remove the cover to gain access to the volume control assembly. Once the cover is removed you can spray the cleaner into the control assembly. Whilst your in there you may want to clean any other controls. Make sure you let the cleaning agent dry thoroughly before you power the unit back up. Another possibility is (if the above dosen't solve it) the control itself has become defective and will need to be replaced

Cannot get steady speaker connections for stereo receiver

Hello Johnsabljic :-)
Being an old stereo, the most probable cause are dirty contacts in all of your controls and switches - especially A-B speaker switches.
Remove all round plastic knobs from your volume, tone, balance (etc.) controls. (they should be pried off carefully with a flat blade screwdriver)
squirt a little contact cleaner (or WD40 if contact cleaner not available. I use a 50 - 50 % WD40 and rubbing alcohol solution in an old Visine container - but if you do this always label the container "Contact Cleaner" as you don't want someone to use it to clean their eyes and go blind)
Squirt about a half a teaspoon of contact cleaner around each rotary shaft where it enters into control surrounded by the nut.
Do this also with all on/off switches and sliding controls as well.
Manually turn all rotary controls back and forth so the solution will work itself in. Move all sliding controls back and forth also, and click all switches on and off as well.
I would let it sit for about an hour before you power it up.
I run into this alot when I refurbish old receivers and eight track players.
Good luck,

Sound problem

Try cleaning the volume control with an electronics switch cleaner spray. If that does not resolve the problem and it seems to happen at low volumes more than load volumes, then the output relay needs to be replaced. Keep us posted. Dan

I have an old Panasonic RF 888 portable radio. It is in excellent condition, except the volume is very low and scratchy.

Have you tried opening up the radio and spraying contact cleaner into the volume potentiometer? This is a common problem in older electronics. The RF 888 has 4 screws on the back. Remove those and you can lift off the back cover. (Be careful because those screws pass through the center of the radio and hold the front cover in place.) Get some electronic cleaner at Radio Shack and spray it into the small opening on the side of the volume control. Rotate the volume several times and let the spray evaporate and see if things sound better.

Sugden A48, one channel keeps cutting out. Sound restored by increasing volume but at low volume goes again.

The volume control may need to be cleaned. Find a spray cleaner made for electronics, relays, ect. and spray it into the volume control from the back side of it where it connects into the circuit board. After getting the cleaner into the volume control, work it in by turning the control back and forth over and over again. Do all of this with the power unplugged from the unit. After you finish cleaning the volume control, plug it back in and turn it on and then check to see if it is working normal. Volume controls can get oxidized and dirty after a few years and require cleaning. I hope this helps, let me know if you need any further help.

Open the receiver and locate the potentiometer for the volume. There should be small openings in which you can spray electrical contact cleaner. The spray can be found at any electronic supply store (Radio Shack). Make sure the product says no or zero residue. I use a product called "Electrosolve". After spraying, immediately rotate the pot back and forth a few times. You may need to repeat this process two or three times. You might as well hit the other controls while you're at it. If several attempts don't eliminate the problem, the pot will need to be replaced.
