Yamaha SY77 Display Repair
Cut away the contacts of
the old EL-Foil
Slide the new EL-Foil
above the original one
Solder the new
EL-Foil
What a mess!
The display goes back
here
The display back in
place
The button PCB back in
place
The metal bar screwed
back in place
Be carefull not to pinch
the cables under the metal bar!
Now that is better!
The audio board on the
side
Now the power supply
which we had to losen to get to the screws of the
keyboard
Be carefull not to pinch
the aftertouch cable!
Do not put the screws of
the keyboard back in place yet!
The card holder
The audio board still
not back in place, rather in the way...
Finally the audio board
is fixed
The card PCB
Now the shielding, fixed
with some of the keyboard screws
Now screw back the
keyboard
Lots of screws
there...
Make sure that all the
cables stick out here
Now put the paper
shielding back
Right side
Left side
CPU Board
Don't forget the
gounding wire
CPU Board 2 back in
place
It IS a good idea to
label all the cables!
Almost finished
The long cable
reconnected
The odd left over
screw....
Back to show room
shine
That was worth all the
work!
