Re: acdelco amfm cassette 2700
If the volume control is scratchy or noisy, first try spraying a cleaner+lube inside the wafer. Like Caig Deoxit D5. Don't use WD-40. Check for cracked solder connections to the circuit board. These are common car stereo volume control problems.
Otherwise, the potentiometer is likely a custom part that AC Delco uses. That would mean pulling the control out, and doing microsurgury to fix it, or getting one from another 2700 radio which was used for many years in many GM's.
If the unit powers up but is dead quiet, the volume control is probably not the problem.

On this Vizio D65x, the volume will change on its own. I don't mean like during commercials where the volume will increase. I mean its like the (+) volume button on the remote is pressed and the actual volume dialog is displayed on the screen going up. It will do this, then the volume may start going down. It might go all the way to "0"or it might stop at a different number, then start going back up. The whole time its doing this, the volume dialog is shown on the screen.
It wont do it until it has been "ON" for 20 or 30 minutes, so it does seem to be heat related.... -
I have a strange fault on a Sony amplifier. The volume control varies the display from MIN, then 1 up to 30 and then MAX as expected. At MIN there is no sound. However, at 1 it is quite loud and increasing above 1 does not change the sound level.
I have tried a Cold Reset as per the service manual.
I have looked at the I2C clock and data to volume control chip IC501 (BD3499FV). Data is only sent to IC501 when the volume is set to MIN or 1. At any other setting no data is sent to IC501.
I have looked all the way through the service manual and tried many online... -
Hi,
I bought a used Marantz SR5007 and it's giving me some issues that I can't seem to really place. It functions well in most settings, ARC mostly works, it has no issues driving my speakers in any of the digital input modes, but I'm having issues running analog inputs in direct or pure direct mode. For some reason in this mode there's distortion for every volume increment I give it, but once the volume is stable it has no issues. Muting creates a loud pop, switching to another source also causes a pop and so does turning off the amp in that mode. Again, no issue in the digital modes.... -
I have this soundbar and when I turn it on it works until I turn the volume above 30.
Then the display show “PROT” protection and shuts off.
I can turn it right back on and it works until volume hits 30 again.
There is a little static on the surround speakers so I unplugged them but still have same problem. I tried unplugging all speakers also and when volume goes above 30 it shuts off.
I can turn the volume above 30 if nothing is playing but as soon as I play something it shuts off.
It will play fine for hours with volume... -
