Question about Music
I have 110V to the transformer but the display is blank. I don't know what the output voltage is supossed to be, and I don't see any fuses or damaged circuitry.
Ok guys. Just got mine XP50 fixed with the "No Display" problem. The LCD screen was blank without text and only shown orange color. The problem is one of the capacitors on the main board was dead. I have replaced all 3 caps on the main board and the problem is solved and if you are a little handy on soldering, you can do it yourself. The 3 caps you should replace are:
- C901 (I used 16V 330MicroF)
- C65 (I used 5V 4.7 MicroF)
- C 902 (I used 16V 330 MicroF)

Turns out this is a design fault with the XP-50 model. My techie says he sees it all the time in this model. The XP-60s and XP-80s are designed differently, he says, and never suffer from this fault. His tip: if you have a unit in working condition, have the capacitors replaced. So, unless you can find a new (i.e.unused) mother board, a second-hand replacement is perhaps just a temporary fix. I've sourced a working second-hand unit and my techie is going to do the modifications required to ensure the "lights out" fault doesn't hit me again. Grim news, but that seems to be the case, and that so many of us have listed the exact same fault, seems to confirm it.

Just encountered the blank display problem on my XP50.
Changed the CR2032 buffer battery and went through the initialization procedure as decribed on the Roland TurboStart-sheet. http://cms.rolandus.com/assets/media/pdf/XP50ts.pdf
After that everything worked fine again.
Hope this helps!
