Prokeys 88 Premium Stage Piano key broken

One of the white keys on my keyboard has broken. The unit was shoved into a van and it must have been in the wrong position for the entire duration of the trip. To explain further, the carrying case is too big for the unit and there was no padding inside the case whatsoever. The keyboard is a gift and I did not look inside before taking it home. Henceforth, the screw-up. I opened her up to take a look inside, just a peek, and four items fell out: 1) a small white piece of curved plastic (looks intact), 2) a small spring, and 3) two (possibly three) little washers (the 3rd was on the floor and I don't know if it belongs to the unit but it looks like the same color even if it is a bit larger and a layer of paint worn off). any advice would be appreciated. If someone can provide a link that leads to a webpage that is a tutorial on opening up the unit even more and replacing the parts that fell out (if these parts belong to the key that is), or a recommendation to a repair place (person) within the New York City (preferably Manhattan) area that is low cost. Thanks.

I have a yamaha p-155 88 key digital piano the upper octave has no sound

Try local Yamaha dealer. They may not make house calls, few people these days do.

What you might try if you are up to the challenge is flip the keyboard over- unplug it. remove the screws that hold the top and bottom shells together- do not let weight of unit rest on keys, especially when opening it up.

Look for physical damage to the keyboard action in the vicinity of the nonfunctional section. Check for broken printed circuit board. If you see any cracks, see where it ends and drill a small hole at the end of the crack to halt propagation. clean the varnish off the circuit tracks and tin the broken tracks first on either side of the break then bridge them with solder. Use a modest sized soldering iron and small diameter (rosin core only) solder. If there are any broken wire connections, resolder them. This may require part of the action to be removed from case- take pictures first before proceeding- make sure they show exactly where the connectors are and what wires are present. etc. You want to be able to refer to the pictures in the event you forget details of disassembly.

If nothing looks out of place, look for solder joints that do not appear to have flown out nicely- reflow them adding a little solder.

I just got this keyboard and want to hear the program # 110 Upright Bass 1 and its Ride Cymbal; I hear the bass, but not the cymbal. The sound is listed in Appendix B on B-14 in the manual. Thanks!

Verify the sound in headphones directly from the unit. The cymbal MAY be panned to one side or the other and will require higher frequency response than some of the piano notes.

I just got a 18 month old privia px130 and when I play the G keys (middle and -1) and the -1C there is a hissing sound. If it only happens in the electric piano setting. If I set it on duet, it happens...

First thing is to verify if the sound is there using headphones. This is important test as it isolates problems in power amps and other connected equipment that may be sensitive to the particular pitch of those keys. If it is in the headphones, then likely you will have to take it to a repair shop as the problem would be very deep in the unit's sound generator hardware.

After transport the keyboard,half of the keyboard below c4 not work.

Probably a cable has come loose inside the unit. The keys are scanned by the internal processor as a matrix of two contacts per key. Often the keyboard is divided into two sections.
You will need to have it repaired or if you are electronically adept, open the case and look for obvious problem.

The external speakers attached to my m audio prokeys 88sx are no longer working. I have replaced the fuses in both but the fuses blow on power up. I then used the keyboard with a set of headphones. One of...

It is NOT likely the keyboard is "killing the speakers"... OR the headphones for that matter.

I suspect the problem is bad switch contacts in the headphone jack that cut off the speaker line outputs when headphones are plugged into the pro keys. These jacks are, to put it bluntly, JUNK... they are EASILY damaged by pulling the cable plugged into them sideways. You will need to service the unit.

Hi there, I have a Nord Stage EX 76 and played a gig on friday night outdoors. I have set the keyboard up and now one or two of the notes occasionally sound much louder than they should. The problem...

What has happened is that one of the contacts on those notes is not working properly. Each key has two contacts. One makes before the other as the key is pressed. The processor MEASURES the time between those as you hit the key to read the VELOCITY you have hit the key with. This velocity is often used for loudness on many voices such as the piano. These contacts are USUALLY conductive rubber pills suspended in silicone rubber "domes". One can disassemble the key area and clean BOTH the black rubber pills and the circuit traces they are pressed against using Q Tips and ONLY 99% isoprophyl alcohol to restore proper operation
One needs to be very careful when disassembling unit as there are many tender ribbon cables and connectors. Best to have clear work area and two people to "control" the halves of the shell while opening..

Prokeys 88 flashes 888 and none of the keys work.

Reset the 88 by switching off --> hold the - and + buttons while turning on. Your device will reset and usually everything should be solved.
