Hi all - I have a Valdesta piano keyboard with one bad key. I was hoping someone might provide some guidance re getting access to the working parts of the key (keyboard) to that I can attempt to repair the bad key.
Thanks in advance -
Wayne

Hello heimtun,

Valdesta is not a brand that I am familiar with, however assuming that the instrument is under warranty, I would contact the retailer from where the instrument was purchased and/or the distributor/manufacturer for assistance.

Kind regards,
James

The Valdesta GTX is a 15-year old keyboard. It is unlikely to be sold new today and if purchased new earlier, it is unlikely to still be under warranty. It appears the OP purchased a keyboard used knowing it had one bad key and is trying to see if a DIY fix can be done. The OP is seeking help from anyone on this forum who still knows anything about this non-mainstream keyboard.

Thanks for your replies... just to clarify... it is a GX-5, it was a gift and not a purchase, it was believed to be in working order when I picked it up... our expectation is that something happened during transportation. And, yes, I'm looking for any guidance for taking it apart. Thanks

If you can't find anything on the net to assist, my procedure would be to just assume the screws you need to remove (for case removal) are all underneath and will be the outermost. Inboard screws would most likely to fasten components to the base, so leave those. I would then expect the upper case to be liftable off (when put right way up again).

I have to do that to my Roland at some point (intermittent fault). That's the procedure for mine. When lifting off the case, watch out for wires attaching it to the base.

TF, I believe you've had your Roland less than a year and it is still under warranty. Of course warranty repair takes time as I found out. I decided to replace my power adapter myself instead of having Roland undertake warranty repair, in my case, because of the time it takes.

I've had my P90 apart several times to repair keys, so my advice is generic. Keys are pretty simple and easy to fix once you get inside. On mine once all the screws are out, you need to lift the top half high enough to disconnect the relatively short wiring connector that connects the top of the piano to the bottom. Once you've got that, it's easy to get at the key. You didn't say what kind of problem the key exhibits, but on mine there is a little spring under each key that somehow manages to work itself out of the position it's supposed to be in.

You might watch some videos on youtube about disassembling various brand keyboards, it will help you get the feel for what's inside.

Far too much trouble, Sloth. Shipping necessary also. Besides that, you know what intermittent faults are like--Scarlet Pimpernel:
"Uh, oh--a repair engineer--quick, hide!" eek

What model is that? I admit I'm interested purely so that I can avoid it, btw. I think I'll start a list of DPs to avoid, so that when I finally can buy one I'll buy one that isn't on my list - if there is one, that is.

Roland FP-30. Intermittent scrunching (mechanical not electrical) noise on some of the black keys. Seems to be something loose (sometimes!).
Incidences have been reported by other owners also, from what I hear.

Thanks @thickfingers. Doesn't sound really serious, and hope it causes no further problems. I think I'll start a list, though. My ancient 1990s Casio CPS-7 which has had admittedly mostly casual use until fairly recently doesn't seem to exhibit any problems (well, except horrible tone and nasty keyboard, but they are 'features') and I wonder if the difference is that these days DPs are just more sophisticated / complicated with more to go wrong.

Pete

If your taking notes, you can note that my FP30 power adapter also died during a storm-related power outage after only about 9 months. Replaced the power adapter on my own nickel (although in theory, like TF, I could have sought warranty service if I was willing to pay shipping one-way) and all was working alright again.

One piece of advice: during disassembly, take pictures. Especially of what screws go where.

Again, thanks for the good input and feedback. Someone asked... what is wrong with key... very simple - physically the key works just like any other key - no sound it produced however.

Thanks - I wasn't going to be as organized as that, and tbh the FP30 was already on my (mental) list for 'various reasons.' I suppose, though, that a database of reported faults on DPs would be a useful thing - at the moment I just make a 'mental note' of ones to avoid, which is probably doomed to fail with my memory being what it is. So far, well, best not to say too much...….
