    Hi guys,
    I need some help here, for my beloved receiver, a sony da50es ,makes a crispy sound when I turn the volume up or down above the 9 o'clock setting. is this dust ? can I fix it myself ? my previous sony amp did it to, I got rid of it because of that, but I love my da50. anyone familiar with this problem.
    ps: it's mainly the left speaker that makes the cracking noise.

    Cheers,

    I had this problem with an amp, it was dirt on the potentiometer that was the volume controll, what you need is called switch cleaner.

    You need to open up the amp, get access to the resistor twidler and spray some of this in and turn it vigorously from min to max (when not on) then let it dry a bit and it should have fixed it.

    I think you have the same problem anyhow, you could allways ring up a local hi fi repair place and just confirm this if they are friendly I am sure they will give you advice for free.

    Regards

    Kahless is right.
    Dirty contacts on your mechanical rotary control. Get spraying!

    Never, never use WD-40 in electronics.
    I can highly recommend the CRC contact cleaner:

    PF™ PRECISION CLEANER
    http://crcindustries.com/

    Contact your Belgian representative listed on the website.

    If you have difficulty, I may be able to get you a very good alternative from Philips Service products.

    guys,
    thank you all very much for your help.
    the problem has been solved more easily then
    I could imagine. i turned of the speakers, then twisted the volume knob very fast in both directions and did this for two minutes.
    guess what, the noise is gone !
    i don't know how long it's gonne last without
    the spray stuff, but by the time he does it again, I'll make sure I have the stuff in.
    Thanks again !
