Galaxy 6000 rds cd stereo problems?

Hi can anyone help me with a problem, I have a 6000 rds cd radio, my clever wife spilt a coffee into the radio now a code pops up, I put the correct code in and press 5 then the radio seems to flash on then it goes back to the reset code, I have taken the radio out and cleaned all the components and I have also discovered that if you press 6 and 5 at the same time it comes onto a test radio station so I know that it is working all ok, any ideas will be much appreciated, cheers Paul.
