this is one of the most disturbing errors, the only easiest option is to replace the main motherboard, if you have a technician, check dry joints on the big ICs.

Yamaha clavinova cvp 7 won't turn om

depending on your level of electrical knowledge it may be possible to diagnose the problem.

First check the obvious - fuse in plug / distribution board - you would be surprised how many times this is missed.

Beyond this proceed at your own risk as mains voltages will be exposed.

If you open up the keyboard you can check the input voltage with a multimeter is arriving at the power transformer input.

There may be fuses on the transformer board - check these - DON'T FORGET TO UNPLUG FROM THE MAINS FIRST

Check the operation of the mains switch - these do fail over a period of time and your instrument is quite old now. Unplug from the board and test for continuity across the pins.DON'T FORGET TO UNPLUG FROM THE MAINS FIRST

If the above doesn't solve the issue then you have a more serious problem such as a power supply board failing or a problem on the main board - seek out a Yamaha service centre who might be able to help.

I am using psr 1100.from last week its not workina.maasege showing assertion failed.pls give a solution

Normally this indicates a problem on the main motherboard.

Always the first thing is a factory reset.
While turning on the keyboard, hold down the right most white key on the keyboard and continue holding it down until the keyboard has finished the start up.

Am looking for a power supply board for yamaha keyboard

Normally if the board is there, I repair failed components. If the board is missing, call Yamaha America parts dept. They MAY have the part you need. That will be the only source of a complete replacement. Power supply boards are usually easily repaired.

There are many ways to attempt a fix with this error you could try firsta boot into safe mode then running msconfig
select the diagnostic startup then reboot in the normal way this might enable you to find your error.

If this fails click the LAUNCH SYSTEM RESTORE which maybe able to use one of your restore points created at an earlier time (usually before an app install) this may give you the fix you require.

Getting an error message when starting the PSR 2100

I would do a factory reset. Search Google for: factory reset PSR 2100.

It will be holding certain buttons or keys down when powering on.
