FORD 2007 RDS stopped working after cleaning buttons!

[Monument]

Hello folks,

Recenlty got a Ford 2007 RDS radio which had coke spilled on it, only the power button worked. I took it apart and cleaned all the buttons with alcohol, after assembly the radio would not turn on anymore. I checked the fuses, diodes on the mainboard but no luck.

There is one thing though, the "tuner" block on the mainboard gets very hot, I havent opened it yet because I need to resolder the frame first.

What went wrong? Im confused.

you need to really clean that by flushing it under a tap.
coke is boric acid, it eats copper tracks - among other things.

Alcohol will not dissolve water based contamination or sugar. If we are talking about "tact" switches, they will have to be replaced.

They are not "Tact" switches, they are like the ones in TV-remotes, rubber and circuit.

Stj, just a little nit - actually, I think that should read 'phosphoric acid'

I think I´ll give up, I just cant find the fault, maybe the buttons are bad.

If you can take apart the button board you may be able to clean the carbon bit on bottom of the buttons and the circuit trace contacts. Contrary to STJ's comment, alcohol will dissolve sugar and water borne contaminants. It may not be as fast acting as other solvents and some soaps or detergents but it will do it. Plain pure water will do it and it's cheaper though.
