Intermittant sound out of a jack

post #1 of 8
Thread Starter 
Hi Guys/Gals,

I own two Sony MZE75 MD player's. The blue model's jacks (it has two) both have "intermittant" sound when you spin the headphone plug around or apply pressure to it with your finger. My question is, do i need to have it serviced or are the jacks dirty and need to be cleaned? I know this is something that happens a lot to walkmans, bu i really would love to have this player in working order again since i used it less than 6 months before this problem occured. I'm currently using the red model for a year without any problems! Thanks for any input!

I'll see if I can tackle this one...

I recall this article by a DAT owner, who thinks the "failure" of jacks comes from the dirt/grease on the plugs. His theory is that every time you plug/unplug, some of the dirt/grease is left in the jack, and after a while can prevent proper contact between the plug and the jack. He recommends wiping the plugs every time before you plug them in.

Given the difference between two E75s (assuming they were both bought new), it could also just be a malfunction on the jacks?

So, I don't know if the jacks can actually be cleaned, but it should be worth an enquiry. I grew up under the impression that once these minijacks go bust, you'll have to throw the entire walkman out; but I do hope that's not the case. Good luck!

Thanks for the info, i really dont wanna throw this unit out since it works fine otherwise

They were both bought new, but from different stores, the "defective" one from a local chain and the one i use now from JandR in Lower Manhattan. I tried cleaning them with a Q-tip but to no avail...how would i go about cleaning the jacks before deciding to go to the Sony service store. Last question, are replacing the jacks expensive?

The phones jack itself isn't an expensive part, but since one of the jacks is a phones/remote combination, that one might be slightly more expensive.

What I always used to think is that these jacks can not be replaced. In reality, you often see hand soldering next to these jacks, so maybe they're not out of the question. Give it a try

A friend of mine had a cassette walkman that had this problem.
She was going to throw it away.

I took it apart, and soldered the headphone leads directly to the board (headphones then permanently connected). It worked for many months.

You can always solder in an external jack, instead of a headphone. The plug the headphone into the jack.

Most headphone jacks in the units are difficult to obtain as parts.

Fixing the unit would cost a lot of labor charges. It may not be worth fixing.

Get some Progold or other contact cleaner, get a miniplug of some cheapie headphone....spray lots on it..plug it in and out repeatedly.

LOL !! The human instinct of going in and out.

Sounds like a good method though (no I'm not being sarcastic)!
