My Beogram 4004 project is about ready to wrap up. The dust cover has been polished and the keypad surface was refurbished at Beolover's workshop. After reassembling everything I found that some of the keypad buttons were not responding consistently. That usually means the contacts are dirty so I removed the keypad contact board to take a look.
Sure enough there was quite a bit of oxidation.
The contacts look pretty tarnished but it isn't anything a fiberglass brush can't fix followed by some Deoxit contact treatment.
This looks much better.
The Beogram 4004 controls are now working perfectly again.
