Hey guys, im working on a yamaha ypp-55...... when you first fire the piano up it just hisses threw the speakers........or headphones jack, doesent matter...... then after 5-10 min the hissing stops and then it will be completely silent....then randomly it will play the demo (i leave it in demo mode) but it sounds very crackly and only plays it for a second or two then it will go back to being silent. Once when it started playing the demo i quickly took it out of demo mode and played some notes on the keys and they were working....then it cut out again and went silent.... the speakers are working fine and so are the keys and all of the buttons and volume control also work.......it really sounds like a main board issue to me......what should i look for? can they be fixed or is it better to just get another one?

the model number on the main board is " yamaha XK626 "
