I have problems with the screen and also one switch (enter) does not react anymore. How did you manage the problem with the wd40? Did You open the Oasys up or put some drops onto the surface?
Best regards

Yes,I think it was Mike Conway who suggested using it(WD40) in another thread from another user experiencing the same issues.
Some of the tact switches are accessible without removing too much,other than the side screws to lift the main panel.I wouldn't spray down direct into the buttons,you'll need to open it up its Only 2 screws either end in the middle of the end cheeks and the main panel swivels up(make sure you tilt the screen to allow it to lift fully on its pivot.
The good thing about WD40 is that it comes with a straw so you maybe able to get a couple of drops onto some switches without taking any circuits apart,mine was the up and down arrows and the zero numeric.
The up/down arrows keys I needed to remove the left circuit board IIRC and the vector joystick assembly too i couldn't get at the Up button with the straw so had to take it apart this assembly included the slider and encoders board,so whilst I had it apart I did all the other buttons too and removed any dust with a paintbrush,All buttons work a treat now,use the straw direct from the nozzle or spray some liquid into the can lid and dab them on with a cotton bud or something you need to get it onto the tact switch shaft one or two Drops should be sufficient,press the switch up and down a few times too whilst doing it.
Took me about an hour or so to take apart and reassemble the left side boards,its a little fiddly especially the vector J/Stick assembly but apply a little common sense I tend to mark up where the screws go and put them into small separate pots so I don't forget where each screw goes,I didn't remove the right hand side board as I was able to get the WD40 onto the 0 key so you might be able to get at the Enter key too as its on the same circuitry line.
I also avoided spraying direct from the WD40 can nozzle incase I soaked other components using the straw will give you more accuracy
