Hitachi 8600e sound problem

[Superduper]

Well, after all these contributions suggesting that you give the boombox a thorough cleaning and deoxidizing, I presumed you already did that.

If you haven't done that yet, then we are all just throwing suggestions into the wind.

Do that first, then come back and report your results.

WD-40 is not a true lubricant -- it is in fact a solvent, so don't use that. And don't use silicone either, because what we want you to do is clean and strip the oxidation from the switches and controls. Lubricating a switch without removing the oxidation is not going to solve your problem. Get the proper spray and go to any electronics store -- they will have what you need. Don't get fancy or creative, just get the right product.

The product i use is designed for small switches and potentiometers. I think it includes some kind of cleaner and lubricant. Atleast it works well .

I now have had the back off and cleaned with lubricant cleaning stray both the input selector and the volume pot but to no avail the sound is still the same :'-( i think the problem is beyond the cleaning thing like you guys said ! time to take somewhere for a fix iff poss!! Cheers Again.

There was no microswitch? If there is one it will be connected via thin metal arm to the input selector. The micro switch is power switch.

The function switch/line in/tape/radio/inputselector was soldered onto a pc board , the switch seemed to be like a ball bearing that the base of the switch rode over ! hard to explain, sorry.
