a mind boggling prob with the radio

[got_boost?]

when i play the radio, cd or tape, once the volume is up to 30 the radio starts cutting in and out of sound intermitantly.
anybody else have this problem or shed some light on it.

another thing that make me want to attack it with a hammer is the volume knob. i turn it up and it knocks the volume down have to knock it up a click at a time

anybody have that problem too???

Isn't 30 kinda loud?

30 is the overheating and needs to cool down
also the problem with the knob is a common fault and dont think ne one has come up with a fix yet.

fixed mine a few weeks ago... took the PCB out, and sprayed loads of contact cleaner into every tiny little gap on the dial, blew it out and gave it an hour to evaporate,

Been fine ever since

i was looking at replacing it as i thought it was a potentiometer, however it's some sort of magical stepped rotary switch

Can you recommend any "contact cleaner" as ive not come accros this before?

Mines been doing that, now the stupid thing wont turn off after i pull the keys out!

I've been using some fancy stuff from RS.... however any contact cleaner will do, halfords do some http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_195717_langId_-1_categoryId_165750

the not turning off thing is a Diode fault i believe.

Thanks for that, i will have to get some and give that a try

I read that so i might just strip it down and have a check if theres anything visually wrong.

 

[EZ Tutty]

if you want to test any of the diodes.....

Set a multimeter to the diode test mode (the one that beeps.. that most people use for continuity check), you should get a single bleep if you connect the test leads over the diode one way, and nothing when connected the other.

Or you can use the resistance function, and you should see a nice low resistance one way, and a high or even infinate resistance the other.

If you find any diodes that conduct both ways, or don't conduct either way thats the dead one.. only problem is you will more than likely have to remove the diode from the circuit for this to work.

I had a problem with the "Telephone Mute Wire" kicking in intermittently. It did display "Telephone" when doing this. so if the display is normal then probably isnt the mute wire, worth checking though.
