audiovox hi comp hcc 1060

Hey all ... just wondering if anyone can help me figure out how to fix-up the functionality of some of the buttons on the front of this older AM FM MPX stereo radio / cassette player (see pics att.)

The '1' & '5' preset station buttons simply will not do anything, nor will the 'LOUD' button.  The actual buttons pop off easily and each have a center plastic pin that pushes on an actuator held captive under a clear plastic bezel.

I tried introducing a drop of De-oxit into each of the holes in the clear plastic bezel in front of the 1 & 5 preset  station button actuators ... which appear to be small, round, metal discs overlaying the PCB contacts, whatever those may be made of.

That didn't work.

To what extent can the clear plastic bezel be removed without destroying the entire assembly?  I'd like to be able to get at the contacts themselves, or, somehow introduce an approrpiate amount of De-oxit under the small, round, metal discs without having to flood each of the holes with liquid De-oxit.

Thanks, Kevin

Hey DYohn ... thanks for posting ... and, if it was you that fixed my photo file names ... thanks for that too ...

Yeah, I really want to get the HCC-1060 working ... plus ... besides my across-the-board notion of trying to keep repairable stuff out of the landfills, the radio / cassette player parts of this unit actually still work fine ... if it comes down to it, I don't absolutely have to have all of the preset station buttons working ... 4 out of 6 ain't too bad ... and I suspect if I bear down on the LOUD button it'll eventually come around (all I need is once - if I can get a 'LOUD' symbol indication in the LCD, I'll leave it be and not trouble it further) ... I've seen this stodgy button behaviour before ... in TV remotes mostly ... whatever the contact compound that is / was used, it typically doesn't age well and usually really likes a shot of De-oxit to bring it around ... thus my reliance on that particular product to sort things out.

I agree, crud in the buttons is not very likely ... just the aging of the contact compound on the PCB underlying the (visible in the last photo) metal push-pad discs ... so ... has any adventurous soul ever attempted to disassemble the clear plastic bezel that covers / contains the button actuator assemblies?

Thanks, Kevin

Hey 'i am an idiot' ... I doubt your handle does you justice ... I won't ask ... but thanks for helping out.

I got as far as Switches > Tactile at digikey but don't see ALPS under 'Series' or 'Manufacturer' and there are 4,445 possibilities.

Any tips on where / how I can use a meter to see if the switches show continuity between the terminals when the buttons are depressed?

Upon further disassembly and closer inspection, I can see that the 'LOUD' & 'ME' button switches do not utilize a captive small metal disc over the actual tactile switch and one can see the switch a lot better (see pics att.).  Also visible in the pics are the very tiny Phillips head screws (5) that hold the PCB / ribbon cable assembly to the clear plastic bezel / housing that I will have to disturb to get at the switches themselves.  My smallest Phillips s.d. won't do the trick - time for another set of tools.

Thanks again, Kevin

After closer inspection, and your comment about a metal disc, those are not physical switches, but just 2 contacts that are dome shaped.  Pressing the button makes the top dome shaped disc touch the rear part of the contact.

See those little screws in your last picture?  Remove them and that will unscrew the plastic light diffuser from the front of

the board.  You can (on some units) remove the membrane that holds the dome shaped discs.  This will expose the 2 contacts

on the ribbon board.  Sometimes they need to be cleaned. 

Hey 'i am an idiot' ... that handle just has to have a story ... I'll search ur username later and figure that out ...

Well, I tried a PH000 (and a PZ0) and those Phillips(?) head screws seem to be smaller even than that ...

I haven't tried yet, but may try some of my smaller flat-head s.d.'s and see if I can get a turn on any of those screws ... damn they're small!

Any thoughts on tools / tool providers?

Thanks, Kevin

I shall investigate forthwith!  Thanks Iaai.
