Yamaha CS-5 Synthesizer Repair.
I successfully repaired my CS-5 last night. I was a bit of a struggle because the previous owner attempted the same thing but destroyed the circuit board contacts in the process... I had to do a bit of surgery but it's quite solid now.
For anyone who would like to know: in order to remove the front panel, you need to take off the two plastic ends and then the 3 screws along the bottom in the back. The top should then be free of the body.
