Roland RF-7 touch screen and electronic buttons do not work.
Hi, we turned on my daughters Roland RF-7 ''2005 model'', and it gets to the grand piano on the digital screen, but there are no up down arrows, no function button on bottom right, just the graphic picture of the grand piano. No button on the keyboard works or lights up. I've unplugged it, turned it on and off, and it just shows the picture if the piano. The piano plays fine, but no touch screen options and no buttons work or light up on power up. Thought maybe a controls lock out so kids can't fiddle with it, but not in user manual. Thanks Rob

Re: Roland RF-7 touch screen and electronic buttons do...
Have you checked with Roland regarding a software update or bios flash for the unit? The problem is obviously software driven so you will need to try and contact them to reflash the EEprom with a newer REV of the software. Roland should still support the unit being that it is only 5 years old. Call their tech support at one of these numbers

Replacing the electrolytic capacitors in this keyboard would require you to be somewhat experienced in electronic soldering, especially the surface mount electrolytics. You should be able to find how-to videos on YouTube if you are curious. You also probably do not need a service manual. The values of the capacitors should be printed directly on them. Replace them all. Replacements can be ordered from Mouser. BUT, I suggest at least bringing in a friend that has experience with these types of repairs. These circuit boards are not designed for inexperienced soldering!
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.
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
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.
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.
