Part 3 - Roland D-70 Removal of the key bed

In order to repair the bad F key on this Roland D-70 keyboard you need to removed the key bed from the chassis. You could possibly do this repair with the key bed still in the chassis, but it will prove to be much harder. So I have elected to separate the key bed from the chassis.
And this video runs through how the key bed is separated from the chassis.
Background:
The Roland D-70 was released in 1990 as the natural successor to the popular Roland D-50. However , it was more a Roland U-20 than it was a Roland D-series synthesisers. If you look indie the instrument you will see the board stamped with Roland U-50 which supports this view.
I bought this synthesiser somewhere between 2009 and 2012. I am not sure exactly when I bought it but I do remember that, as is my standard practice after I acquire an instrument I will normally change the battery.
I purchased it because I wanted a 76 note keyboard, I didn't at the time have a Roland D-50 and wanted a D-series synthesiser and I wanted a controller for the MIDI setup I had at the time.
Anyhow some where between my many moves over the last 10 years, both studio and home, it has been damaged. This series of videos will fix these issues and restore the Roland D-70 back to full operational health.
