Roland 3000 Digital Piano 88-Key Full-size weighted keyboard
Some keys don't work at all (two); several keys must be played quite firmly in order to work. This occurs across all voices.
Oh, and one key sticks.
1) what causes this
2) who is my best bet for a correct fix - electronics specialist, music store, ???
3) who can likely fix it right, for the least $$$ (I'm broke)
Re: Roland 3000 Digital Piano 88-Key Full-size weighted...
It's not really for the faint of heart, but generally this is caused by gunk getting into the key circutry. Underlying the 3000's keyboard is a silicone pad with 2 contacts on it, the measurement between each being hit is the issue usually but yours just sounds like there's something in there causing a physical or contact obstruction.
What you really want to do is to remove the keys and clean everything but this isn't easy... You could try using 99% alcohol (from a pharmacy) to clean inside it which may well help you.
Which may help you work out how to do the disassembly if you are brave, but I would start with pouring some alcohol in and poking it and hoping for the best 1st. It sounds crude, but it works amazingly well with some things.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

This normally indicates dust is present. I don't suppose you own a cat or dog? :) It's amazing what manages to find its way through the gaps! If you're not quite up to diy, send it to your local technician. They'll know exactly what the problem is and with any luck - clean it and assemble it within an hour or so!
In a word, NO. They simulate weighted keys by adding spring force and inertial weights. It gives a more realistic feel, however it is stiffer, more like an acoustic piano. You will develop strength and get used to them... If you have been used to playing some synths that are not hammer weighted these keys will seem very springy.
Yep... Roland pedals are reversed, that is, normally closed contacts. Unlike some Yamaha keyboards, the Casio doesn't have an inversion function available. You have two choices to solve this: 1. Buy a pedal with the corect sense 2. Open the Roland pedal and MAYBE with a soldering iron you can move a wire to select a contact with the opposite sense.
I have two Yamaha's and I will say they are maintainable. Almost ALL the weighted piano key models use a keyboard made by one company as I understand it. I can easily get service manuals for the Yamaha, not quite as easy for the Roland... same goes for repair parts. Your decision... listen to each and decide. Hint: Use a set of headphones to do the compparision rather than internal speakers as the orientation in a music store can drastically change the sound.
The Korg SV188 has stunning realism in the Grand Piano arena. It uses a 12AX7 tube in the preamp output for that classic analog warmth lacking in so many garden market digital stage pianos these days. It has weighted hammer action and carries a price tag of $1,699.00 at American Musical Supply.com They even throw in a extra years coverage at no cost. The Yamaha MOXF6 88 key (same price) is another fine grand piano that wont disappointed but be prepared for a large learning curve learning all the rest of it functions, there are plenty to chose from. Roland wins hands down with its RD300nx, $1,799.00 and the RD700NX $2,699.00 simply the best digital stage pianos money can buy . Look up the specs at AMS
Sorry I didn't find you 'til now. I just got the same problem. If you haven't found out already, Roland has them available from the support dept. (323-890-3740) at $9.00 a piece or $200 for a full set of 88. They say they've re-designed them to be more durable.
You will likely have to double that budget to get anything decent... but look for a Yamaha in the PSR series (61 keys minimum). To get a full 88 key, you might have to be up in the $400 range for anything really decent.
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.
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.
