Help A Fellow Keyboard Player?

We have a gear for music mp8820 electric piano that I bought 2nd hand a few years ago suddenly out of nowhere over Christmas it has stopped working. I have tried changing the adaptor it says it needs a 2500 ma 12v dc adaptor for many years I have used a 1500ma dc one with it I am getting no power at all from it and the adaptors lights are on I have attached a picture of the circuit board I use the piano every day and am losing work when I cannot play it if there is anything that can be done ASAP it would be appreciated.
