Hi:
I have a hand down Roland HP-4500s.
The sound and keys are still good, except
one of the keys is loud. I need to clean the contact.

However, I am scratching my head on how to open the top cover.
I see lots of screws, but I haven't been able to identify which ones are holding the cover down.

Any help is appreciated.

TIA.

There's much more to know about than just how to open it up.

I have a Yamaha Clavinova. Opening it up was a chore. I've had to do it several times.
Then removing the keybed to service it was a chore ... and the steps were NOT AT ALL obvious.

So please buy the service manual. You'll be glad you did.
