My Ka band is stuck on - what can I do??

**gls** · 10-06-2005, 04:18 PM

I have an 855 STi, and I love it and it still works and detects all bands from miles away. Granted, it has been dropped a lot and has been saving me for quite a few years.

Now, when I turn it on, no matter where I am in the city or the country, the Ka band is non stop. I have even changed vehicles and it is still the same. Can anyone help me? I have taken it apart quite a few times. And just on the weekend I took it apart and noticed a residue on the surface of the board. I cleaned it yet it is still crazy.

I had this issue before, but usually you just need to wiggle the jack, but this is worse and it is constant. Thanks for any suggestions.

855 STi, I had one and mine blew up.

So maybe don't trust my instructions

Probably the unit went out of calibration. Maybe you can adjust the mixers so it goes back to where it should be.

What do you mean - mixers? Can I get a repair manual somewhere? T.

now don't quote me on this but i'm pretty sure mixers are are little screws that you have to ajust every so slighty,if any of you have taken apart an old radio you would of noticed on the circut board a type of electronic tuner thingy that usally has a place for a flat head screw driver ,it probably has melted wax or plastic over it so to tell the technician you have tinkered with it to void your warranty?

hope this helps :?

Actually, that wax type stuff is lock-tite. It is designed to stop potentiometers from wiggling out of their settings. After they have calibrated the detector in the factory. It just stops them from moving. I would just mark the pot (little screw) where it was and twist it one way and the other and then return it back to its exact spot again where it was. That might do the trick. Make sure you use a precision plastic screwdriver though so it doesnt take and static hits.

I am in an electronics course, and my instructer said "your supposed to use wax to hold the potentiometer screw and also brand it with a little stamp so they know who ****ed it up when they get them back.

I must be tightening the wrong screws. The only screws I see are the ones that hold the board to the unit. Does any one have any other ideas as to why my detector still thinks it's detecting a Ka band? It is going crazy. Any help is appreciated (with pictures if you can). Thanks.

Can someone post up a picture of these locite covered screws please? I am obviously missing something. Thanks so much.
