You may need to clean the contacts which are usually conductive rubber. I explained stuff for another Roland problem with two keys that were intermittent. I have an EP-7 that I had to do the cleaning of the key contacts. Use 91 or 99 % Isoprophyl alcohol to clean BOTH the conductive "pill" (Black under silicone rubber domes) AND the traces on the board where they press. Clean gently as the traces have a hard black coating.

White spirit is NOT what you should use. Mineral spirit leaves a residue film.
Use 99% isoprophyl alcohol.
ALSO inspect the contactboard for cracks by candeling with bright light behind it.

Testimonial: "bur isnt it strange that certain keys have stopped working? ie most the A keys"
Did you ever get hold of an FP-8 service manual? The weight replacement is relatively simple: The case opens by removal of eight screws, four at each end on the underside. The top then hinges up. Keyboard assembly is removed by first unplugging the two white ribbon connectors at the center, then removing the screws at the front edge (underneath) and the screws (gold) at the back of the assembly (accessible from the top). Keys pop out by spreading the two "wings" at the pivot point, and then the weights (Roland calls them "hammers") lift out. Roland will sell you new ones, but I have no idea whether the replacements are any better than the originals. I've done two of these pianos so far, and have a third waiting to be worked on. I do have a service manual, but I think I downloaded it freebee somewhere.
The other failure mode on this piano is the electolytic coupling caps on the output board - I've replaced all of them on both pianos - don't remember the value offhand.

You either did not get the ribbon cable seated OR got it upside down.
If this cable is the flat ribbon with exposed solder plated points of contact, OFTEN those connectors have a latch to release by GENTLY moving tabs on eaither side in the direction of pulling the cable out. This lock MUST be moved out slightly to allow the cable to seat properly. The solder plated contacts will be FULLY into the connector when seated properly.
These cables ALSO can be inserted backwards and NO connection will be made.

Roland FP is a nice keyboard but has a known problem on cracking key weights. There is a counter weight under each key to push the key upward. There are two sizes of weight beams, longer one for white keys and shorter one for black keys. Roland did not make the original weight beams strong enough to last. They will crack and eventually break. When it happens, the key will stay down. Fortunately, they can be easily replaced.
Roland FP-8 has 4 black screws at the bottom on each side end. Remove the screws, flip the ends up and expose the interior. Near the hinge of the problematic key, carefully ply open the hinge tabs and remove the key from the hinge. You will find a weight beam under the key. Remove and inspect the weight. There should be a metal wrapped in a plastic beam. If the metal part is missing, find the missing part and replace with a new beam. You can order weight beams from Roland. It costs about $10 each plus shipping. Put everything back in the reversed order.
