Mackie 1402 vlz pro needs repair

[n4085b]

Thought I would throw this question out to the forum. I've got a Mackie 1402vlz pro that I bought new a few years ago. Its out of warranty and upon inspection of Mackie's site, is now a discontinued item. It has one of the line in jacks inop on chnl 13-14. Tried cleaning the jack itself with Deoxit and took the mixer apart but could not see anything obviously wrong in that area. Who do you guys use to fix stuff like this? Is it even worth fixing? Any ideas for repairing it in the AUS/SAT, TX areas perhaps? The shop that they have listed on the Mackie site has lots of neg reviews.

Thanks in advance!
