Home Theater Questions? Ask a Technician for Answers ASAP
Hello, Sorry you're having problems. Can you please tell me what method you tried cleaning with? Did you use a contact cleaner inside of the volume control?
Please let me know and we can proceed.
When the volume crackles like this, it's caused by dirty contacts inside of the volume potentiometer. The method to clean the volume pot, is to use a contact cleaner like "DeOxit" (at the link below) and with the top of the receiver removed (unit unplugged as well), locate the small opening in the back of the volume pot, and liberally spray the tip of the De-Oxit spray can into this opening while simultaneously working the volume pot up and down. Repeat this procedure several times and this will clean the contacts and eliminate the crackling sound.
This is common with ALL receivers and amplifiers when they reach several years of age, as dust and dirt migrates into the volume control by attracting to the heat generated within the receiver (heat attracts dust). The steps above are what is needed to fix the issue.
I'm unsure why you're unable to reply, but if this is something you're not comfortable with, then a shop will typically charge $50 in labor to clean the potentiometer (pot) in the unit and can be located using the link below:
