Receiver JVC RX500B volume control popping through speakers
Greetings,
Fixing this thing for my sister as a favour. The volume control is digital and as one pressed the buttons for volume up or down you can hear the steps coming through the speaker. It sounds lke static pops. I have looked through the circuit and haven't found anything yet. Thinking of targetting the chip responsible for volume control (if I can find it) and maybe adding capacitors to damp out the pops.. As this unit it old could the capacitors inside have dried up and created this popping sound? Any other parts that may be responsible? |
