Will probably need to be diassembled and cleaned. Either a sticking key or a compromised contact on the circuit board. Any electronics repair shop should be able to fix this.

Make sure there is not a switch that makes it output to external speakers.

talk to a technician n check its audio amp ic, replace.

My Roland xp-50 everything work fantastic but no sound out.

Make sure that the level of the headphone out put is open. Make sure it is on manual adjustment and no auto level. And test your headphone on a other device to clear that your headphone is not broken. If all these options are correct you headphone pre amp of the XP 50 may be damaged or broken.

Looks like capacitor problem.Check power supply section also.

Yes, he is full of it. For parts try Digikey.com, Mouser.com, and AntiqueElectronicSupply.

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)
