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.

SOURCE: My roland xp-50 keyboard is dead.

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)

There are lots of IC's in the unit. Order from Roland support parts. That will be the only source.

Repair for vintage keyboards.

Static is usually the result of a bad connection. I suspect there is a bad solder joint. If you are electronically inclined, use a listening device or oscilloscope and connect it to the volume control terminals if it is not present on the input to the volume control then it is the volume control that is bad which happens in old equipment best solution is replacing the volume control or you can try cleaning it with an aerosol product for this purpose.

No sound from my xp-50 keyboard. I replaced the battery, screen is lit, but no sound

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

I have a roland xp-50 with no power at all. What should I try?

ftp://ftp.roland.co.uk/productsupport/

I would start by checking AC cord is good, look for a blown fuse (BE CAREFUL !!!!) or maybe a defective OFF/ON switch. This keyboard is from the mid 1990's so PLEASE consider this before having it expertly repaired. $$$$$$$

Roland f-50 First 7 right hand whites keys appear to have lost volume and sound off / flat.

One of the lines in the keyboard scanner has opened up. I have an idea what it might be and it is a nasty problem involving circuit traces that are silver conductive paint on a plastic insulating base that separate from a jumper at each end of the strip that the key contacts are made by conductive rubber pills pressed down by the keys. The contact of the flexible circuit under the keys to the jumper cable can be broken by vibration. I have an EPS7 with the problem and other than replacing the whole contact strip under the keys it really has no easy solution.You should probably have a Roland shop look at this problem. If your unit has this same arrangement it is repairable only by replacing the whole key contact strip.

I have a very loud hiss/buzz sound coming from my Roland. It goes away if I lower the high volume knob. This just starred to happen recently. I tried changing connections from ch1-4 but no fix.

If this ties to a keyboard, make sure the keyboard and this are BOTH plugged into the same receptacle. You should send a higher level from the keyboard (turn volume up to around 70% or so) and use less volume at the input gain of this amp. Use more at master volume if the amp has one if needed. If the hiss is there with NO input cables plugged in and input gains at 50%, that is objectionable, the amp probably needs servicing. Unused channel gains should be clear down.

Roland keyboard. Extremely static-y speakers. Cuts out.

It sounds like your volume slider is dirty. Try carefully and judiciously spraying a good quality contact cleaner into the slider and working it. do not use a lot. It only takes a little. Also do not use WD40.
