The first thing is to verify that it is supposed to work with a particular performance. NOT ALL voices support modulation as well as pitch bend and with an arranger you can turn this feature on and off, usually in the utility functions and then save the setting for each performance/song. Read you user manual about modulation. On page 271 of your manual they show that the joystick is assignable. You have to assign the functions to the effect you want.

Reading your user manual on page 12, bullet 9 you will find the method of changing the contrast of the display. There is no brightness adjustment possible, however the contrast DRASTICALLY affects the readability of the display.

It sounds like your ROM battery, which the ROM contains and stores the patches for the keyboard, has gone completely dead and your keyboard is dead in the water. However, if you can get a MIDI to USB converter and get the battery changed, then you can reload the patches back onto the keyboard. I have worked on a Korg M1 Workstation and have had to replace the battery(CR2032) and then had to run a program called "MIDI-OX" which also gave me access to the patches needed in order to restore the keyboard to factory patch settings. http://www.midiox.com/ Take a look at this AFTER you have gotten the battery replaced. I will tell you that replacing most batteries is a very intricate job as, the bottom of the keyboard has to be removed, as well as a lot of the internal boards. I had to draw a diagram and mark certain pieces so I would know where they went and in what order they have to be re-attached. My advice is take it to someone who works on electronics unless you want to DIY (not recommended) to get the battery replaced. Hope this helps.
