I believe organ hasn't been played or even turned on in over 10 years. The top keyboard plays if I turn on a setting such as piano or trumpet however I can't just get the organ keys to play.

Hi ...
There are flexible cables that connect the keys to the main electronics. The connectors for those cables sometimes age poorly..
It is fixable. But dont "get taken" on a repair.
If it's just resoldering a few points,it shouldnt be more than $100.00

I'm sorry but it sounds like you will have to have it repaired professionally.

SOURCE: Wurlitzer organ, highest key plays note one octave too low.

If this is the kind of organ with the wire sticking out of the key that makes contact with the bus bar to create the note you will have to make sure that key is operating the same as adjacent keys. The busbars have to be clean and the contact wires have to be clean. Sometimes when cleaning the wires they will spring out of place and not make contact with the appropriate bus bars. Check that key against the rest and see what you find. Hope this helps.

SOURCE: What causes the static background noise in my keyboard?

Hi,

It sounds as though you have a static electricity problem in your volume pot. Although there are sprays on the market that you can use for all of the electrical switches on your keyboard which removes and suppresses static electricity, one way to make sure this is the problem is to slide your volume slider to maximum, then minimum, up and down about 10 to 20 times, if the scratchy sound begins to diminish, you knwo the problem lies there. As a matter of fact, if you do it long enough, the sound may go away altogether, although without a good spray of electronics cleaner or electrical contact cleaner (which you can find at stores like home depot or online, even eBay), the sound will return.

If this is not the case, and the scratchy static sound does not go away or depreciate, it could be your cords or even static on the pc board inside the unit. If you are confident that you can crack the case on your board without causign damage, then get a screwdriver and open the case (all screws are located on teh bottom of the unit) and give it a good spraying with electrical contact cleaner on all of the contacts and even a once over on all of the circuit boards. Do not wet the circuit boards with too much spray, rather, give them a light misting.

For areas where you plug in, like your 1/4 inputs, your midi ins and outs, and headphone jack, spray the contact cleaner inside the holes. You don't have to worry about spraying too much in these areas. Just do not oversaturate.

Hope this helps, and thanks for using FixYa

SOURCE: How to remove piano keys from Roland KR 4700

You probably need to just clean the circuit board and the conductive rubber contacts. There are two per key to facilitate reading the key velocity.

Use 99% isoprophyl alcohol and Q-Tips to clean both the board and the rubber contacts.

A rod is inserted lengthwise to hold the hammer weights while removing the boards. Use dowels from each end inserted about halfway back between the keys and the weight rods. Use a 1/4 inch dowel rod.

You have to take out a few screws to remove the boards from the key assembly. Be careful of the cables.
