My Roland FP8 plays very quietly through its own speakers, through an external amp & speaker and through the earphones. There is a hissing/crackling/static sound too from the speakers. Anyone

If I connect an external source like a phone or such, the speakers play fine. png free

Go to "YouTube" and type in "Roland FP8 piano repair"

Sounds like a blown motherboard to me. It needs to go to the shop.

Hi, With my sound engineers hat on I would use a small PA. mixer, amp and speakers!!!!
For quality you need a full, flat frequency range system with good headroom.
I assume this is for your own listening, when using an acoustic kit?
There are one box solutions.

1. Drum amps. Like a monitor wedge with an amp, Roland do a PM-10, Various other makes are available.
2. General purpose powered wedge.
3. Keyboard Amp, these are full range and available in various sizes.
4. Bass amp with high frequency driver (tweeter), not the best but will have good bottom end.
5. Powered or active speaker, much like a powered wedge, but a different shape, needs an input volume control.

All these systems need to have large bass units, 10 inch minimum, and will be in mono. Two will give you stereo,
How loud depends primarily on the sensitivity of the speaker. But manufactures insist on selling things by power. Worth looking this up.
At a couple of feet away, 20 watts should do it, with high sensitivity speakers, more likely you find most things as above start at about 70 Watts.
Good luck, I hope I have widened you choices a bit.
All the best, Chris the Fader.

Rubber cement is an excellent for minor speaker cone damage but if you feel that a replacement is required, try MCM Electronics online. They carry lots-o-speaker replacements. Be sure to match wattage and impedance (ohms) of the speaker though as these are important spec's.

First thing is to determine if sound is from the speaker or possibly the cabinet. If from the cabinet it is likely the power transformer is vibrating the chassis. This sometimes can be cured by adjusting the mounting bolts.
If the sound is from the speaker, then an electronic "cure" is needed. Please note that a very quiet hum is normal but if you can hear it 5 foot away, that is un-normal.

The hum would probably be due to failing component in the power supply. Unles you are adept at electronic repair, best to take it in for servicing.

sounds like you have blown the top end, try replacing it with a spare from your other ones.

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.

It sounds to me like you have blown the internal speaker.

It sounds like your volume slider is dirty. Try carefully and judiciously spraying a good quality contact cleaner into the slider and working it. do not use a lot. It only takes a little. Also do not use WD40.
