Roland replacement parts for JD800 ?

Recommended Posts

Does anyone know if Roland still sells replacements for JD800 ?

 

I have a JD800 here with a broken keyboard PCB which I ask to replace...

 

Thanks ! ;)

Roland still has some replacement parts for the JD800, though it's hit or miss depending on what you need. You just have to call them and see if they have the part you're looking for.

I had mine keybed replaced by Roland Canada. They had to order parts from Japan, but there aren't too many left, if any now.

Here's what appears on vintageplanet:

RL-7626621000A - Key Contact PCB, Keyboard Flat Cables and Connector Board:

 

The original parts are no longer available. If any of these fails,

all will have to be replaced with a complete new set as follows:

 

RL-22935230 Contact Board (flexible strip) . . . . . . . . NOS 49.16 58.50

RL-00784978 Connector Board . . . . . . . . . . . . . . . NOS 24.75 29.45

RL-00784989 Flat Cable 42cm/26-p . . . . . . . . . . . . . NOS 9.87 11,75

 

Hope this list includes what it missing there :rolleyes:

 

The unit is told to have a broken keyboard PCB, and will be sold for about 150$...

Haven't seen it myslef yet though.

I don't want to get into this too deep this morning, but I will send out a word of warning.

 

If you order the current keyboard underlayment flexable green circuit from RolandUS parts, it has been modified and IS NOT a direct replacement. The part number didn't change and there's no warning that this is the case.

 

It takes extensive modification.

 

The difference is the way it terminates. The layout or order of pin out was changed.

 

Worst part is that Roland parts dept really isn't aware it happened and the parts are non-returnable.

 

It CAN work (I've done it), but the sub-connector assembly board must be re-soldered and re-ordered AND you must tweak the white cable that heads to the motherboard.

 

Serious PITA if you don't have another JD800 nearby to use for comparison.

 

I see you're from Jupiter, so I can't speak to how Roland operates there.

Haven't seen it myself yet though.

 

The way this works is that the Contact Board is now different, so it won't correctly fit your Connector Board.

 

So they sell you a new Connector Board...which is the same as the OLD Connector Board with parts simply moved around. You could use your old Connector Board, but you must remove two parts and relocate them on the board (move them to different locations on the Connector Board). All the holes already exist on the Connector Board for this relocation -- you just desolder, remove, relocate and solder.

 

Then, I'm curious how the Flat Cable differs from the original because it won't come out right in my experience...it needs to be cut up a bit with a razor knife and switched around a bit. I can't remember now...but I believe it involves getting the aftertouch portion of the ribbon cable moved to the opposite end of the termination at the mother board.
