Roland JD800 Repair2

Description

Roland JD800 Repair2:

Roland JD800 Faults:

• Severe red glue everywhere.
• Screen encoder value parameters jumping all over the place.

Removing the corrosive red glue from vintage Roland keybeds is not a quick exercise.

The keys have to be soaked in caustic solution to release the weights, this often involves manually picking them out and clearing the mess out too if one wants to be thorough.

They then need to be washed and dried before the task of re-gluing them back again is undertaken.

In this unit, some of the glue had reached the far ends of the key return springs, it had dripped all over the contact membrane and eaten away the fine conductive traces to the point where removal of the glue was just causing more damage. The only plus side was that the glue was fairly easily removed from the grey rubber contact strips.

If one trace gets destroyed then you loose each key in each octave which ain’t much use.

Roland JD800 works done:

There is a brand new modern designed key contact membrane replacement kit available from Guy at www.supersynthprojects.com

It is easy to install, accurate, high quality and a real serious bit of kit and I have to take my hat off to him for having the skills to be able to design it in the first place then get it manufactured. It arrived promptly and was installed that same day, no instructions were needed as its pretty obvious whats what. I believe that any JD800 that has had red glue dripping on anything but the metal parts is a ticking time bomb waiting to fail. It’s prudent to just get this kit and have peace of mind for future.

• The power supply was refurbished.
• The faders were all cleaned.
• The keybed was completely cleaned as were the keys.
• The return springs were re-greased as were the keys themselves.
