what a good combination, have u opened up the shielding ? is there much corrosion on the PCB ? try to clean with IPA, and then put it in an ultrasonic cleaner cos a couple of cycles, then dry it out and heat it up. make sure u dont see any corrosion left on the board, if you do, resolder the contact points. perhaps also try it with a new battery, more work in repairing an if4 then an if3. good luck :)
 
== Update ==
 
normally i use distilled water in the ultrasonic cleaner, then i heat it up then i reflow it
