Humminbird 1199 exit switch

Posting for a bass fishing friend, I understand this is a common problem in this generation of Humminbird units, I have 3 so am also interested, hoping Rickie or someone else can offer suggestions

I have a 1199 with a sticky "Exit" switch. Humminbird has no interest in servicing the unit. I think that it's just a matter of cleaning (and maybe lubing) the switch but I can find no information on the "negatives" of opening up the case. Experience anyone?
Final thought. Anyone have any experience with any organization that does out of warranty repair work on Humminbird gear?
Thanks, help would be appreciated. Hate to toss out a perfectly good piece of equipment over a fifty cent switch.

Thanks

*Place the unit face down on a towel or similar non slip material ...
*Remove all the screws on the back cabinet panel except for the screws around the cable collector panel - these screws connect the cable collector panel to the back cabinet half - these screws do not need to be removed ...
*Separate the 2 halves of the cabinet just slightly - 1 inch or so ... taking care to keep the cabinet gasket on one cabinet half or the other - doesn’t matter which half ...
*Only open the 2 halves enough to provide access to the wire connections from the back cabinet cable connections and where those cable connections “quick connectors” push into the mother board ...

*Take pix of every wire “quick connector” at the motherboard before disconnecting - all 4 edges of the unit ...
*Disconnect the “quick connector”s from the motherboard ... this should allow the cabinet back half to be removed ...

*Remove the ribbon cable from the board behind the push buttons ...

*Remove the screws holding this board ...

*Remove the white plastic spacer ...

*Remove the rubber button collective sheet ...

*Clean the buildup gunk from around each rubber button protrusion ... and all gunk visible ...

*Re-assemble in reverse order ...

Thank you Rickie

Rickie - do you recommend any type of lubricant around the buttons before reassembly? Maybe some plummers grease??

IMHO NO grease. It will just cause more dirt to accumulate.

I agree totally ...

Just as Rickie layer it out. I will add a couple of caution’s. Be really careful when removing and reinstalling the ribbon cable. Also on the mounting screws for case half’s, you will find each screw has a tiny washer and “o” ring seal. Make sure that each screw has these in place as you reassemble. These help keep your unit waterproof.
