Yes. LCDs require back lighting.Think of an LCD as a window blind. It has to open to let the sun shine through, or close when you don't want the light. The LCD, works much the same way. it opens for light(in this case, not he sun, but a man made light, bulb, LEDs, etc. When your back lighting goes away, the display is darker, or completely dark. You will need to repair whatever method is used for back lighting. If you require additional assistance, or would like to inquire about a repair, please visit my website at audioseviceclinic.com. Thank you.

could be a power saving feature check your manual

Hi!
Most cases you can replace just the backlight itself, not the whole display. Contact http://www.telesisgear.com/index.html for the part. It's a relatively simple repair, but if you can't do it yourself, most any music repair shop or music tech can take care of it short order.

Yes. It is a fluorescent tube. It has to be from the OEM though.. It usually comes as a diver board and tube assy.

No, LED are rated according to the amount of current they can carry.
they wil only burn out if one was to exceed their value.

yes maybe you may fined that some of the power to the led is being blocked by causing a larger resistant to the led which will cause it not to light up as bright.

It could be the light, or it could be the inverter that powers the backlight. Try asking this guy: http://www.mikebarden.com/technics-electronic-digital-kn-pr-px-piano-keyboard-ensemble-repairs/

Only by replacing the screen.

I don't see why Technics couldn't replace or fix it.
