Sounds like what happens with mine -- the key weights broke. I have solved this by opening it up and stealing the weights from similar keys at the lowest or highest end of the keyboard. The keys pop off by messing with the back ends, and the weights just come right out. Not bad really. Opening the unit is just a matter of finding the right screws, there are 4 larger ones on the left and right undersides and 4 more small ones in the back. Intelligent hunting will find them. Good luck!

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.

There's a good thread on a similar issue at:

http://www.electronicspoint.com/roland-hp-3000s-digital-piano-dodgy-note-t18946.html

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.

SOURCE: It's a Roland HP-7e digital piano about three years old.

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.

It sounds as if the membrane under the key needs to be replaced. It can be done with some careful work yourself but you might want to consider having it serviced by a Roland dealer as apparently the parts are becoming scarce. Hope this helps.

SOURCE: I have a Roland HP 2e digital piano - Foot pedal problem

The ROLAND pianos USUALLY require that you use a normally closed sustain pedal.

MANY pedals are the opposite and close when pressed. SOMETIMES you can open the pedal and reverse the way the switch works.

SOURCE: Key won't come back up on Roland digital piano

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.

Are the currently manufactured Roland Home Piano series pedal assemblies compatible with the Roland HP237?


This wish an after market pedal, or the original 3's connector? If the keyboard is on when you plug and unplug that, it is likely due to a voltage reference getting confused. Usually when you get constant sustain then most likely a switch is stuck closed, or open, down there in the pedal. How these things work normally is that a pliable switch is opened, for sustain, or closed. It depends on the keyboard. Some keyboards have a setting inside them to accommodate both types of pedals, and some pedals have a switch to choose either. Your keyboard does not have a setting that I can tell, other than adjustments for a resonance option (nice feature). I am not sure the newer RPU-3 pedal is compatible, it seems to be for the newer models. If you are handy with a volt meter, then can check the cable's pins for a common, then a pin that changes with each pedal (use continuity mode, beeps when circuit is closed). Could be a piece of dust is in there, or hair or carpet stuff, and a good cleaning would fix that from blocking the normal function. Manual Link: http://media.rolandus.com/manuals/HP-237_OM.pdf

I Have a Casio Privia Digital Piano and a Roland DP-10 pedal. The pedal function is inverted. When I press it stops the sustain and the effect comes back when I release the pedal. The pedal does not have...


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.

Hi, I am undecided about which digital piano to buy: Yamaha Arius 141 or Roland F110? help appreciated, thanks, karol.


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.

Need help in choosing the best digital piano you can recommend for me for A budget of 2500-3000 usd


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

I have a Roland HP 101 digital piano however certain dont sound


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.

I need a service manual for Roland FP8 piano, or..


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.
