Omega 8000 Audio loss

A

all iron

Member
Went out this morning and hunted for a few hours at a couple different places and what i was experiencing was an audio loss.
I could see the VDI reading the signal but couldn't here it all the time ( bummer ) just a lot of popping and cracking.
Even when pinpointing it would cut out.
Pulled the headphone jack out and still no sound.
Changed the battery with no luck.

So was contemplating sending it in for a tune up.
By the time i got to the 2nd spot i was wondering if the coil cover might have been causing the problem so i yanked it off and there was a lot of gook underneath.
I cleaned the coil and the problem has seemed to go away :)

I know i have read other posts of sound loss and was wondering what the outcome was.

PS: I bet these hot summer days can take a toll on soldered connections. I leave my detector in the truck for days on end and that cant be good.
 
What was the gook made off? And if ya got a coil cover.........well....its well known that foreign debris within coil covers cause a myriad of weird symptoms.
 
Sure does, gook was just fine grit wet sandy stuff ( might have been fine gold ) :biggrin:
Went ahead and opened up the housing just to check connections, all looks fine.
Took a can of air and blew it out real good while i was in there.... there was quite a bit off dust inside also.
 
The 2 headphone jacks are wired such that plugging a headphone into either one, will disconnect the speaker. If there were dirt on the contacts of the n/c switch section of either jack, the speaker would not work. If you have further problems with it, try some electronic contact cleaner spray on those contact points, then plug/unplug the headphones several times, to clean those contact points.
 
Most folks don't realize that dust holds an electrostatic charge......thats why dust needs to be blown out of computers with non-electrostatic charge canned air. Glad problem solved.
Sand in a coil cover is especially nasty if its mineralized.
 
Mine only works with headphones connected. Will try some air and contact cleaner, worth a try before sending it back.
 
Experienced a little audio loss again today.
No coil cover this time to hold the gook
