Hello, I've got a problem with my jpm system 5 board (with yamaha sampled sound), it's not working except the LED's, battery was leaking and removed, cleaned the area and found 1 failure on the board (copperarea, ofcourse repaired it). What's happened: al the 4 leds are going on, the reset led is flashing (every few seconds), sometimes if I put the power on I hear a sound from the speaker. Any ideas where to look for? Sorry for the poor english (dutch). Thanks
