Hey,
Thanks everybody for your explanations
So I did check the battery Voltage ( in the service manual they said it should be between 3.6V and 4.10) my multimeter gives me 3.0V but since the battery is no more the same it's correct.
I checked the power supply, every VR have been verified.
I put a 56K on the 2pin connector of the KLM-376 board (should I use an 1/4W or 1W resistance?) then I turned the VR1 on the KLM-367...but nothing happened.
Bank A, Program 1 and Tape Enable are lighting on with or without the 56K connector. whatever how i turn to the clockwise or the counterclockwise theLEDs remain the same.
When I turn the power on ( without the 2pin 56K) I noticed the Tape LED is always lit. if I switch to enable the LED turns brighter...
Should I continue the procedure with D/A adjustment?
PS : I noticed something weird when I press a key six time in a row the D10 on the unit 4 and the unit 5 don't light. Does it mean 2 voices are kind of broken?
Cheers!
Vincent
