Yamaha psr-e333. Can switch on but cannot play even the grandpiano func. Its just "yamaha" written on the display..

To start with try a master reset, whilst the instrument is off press and hold the top (highest) sounding key whilst turning on.
When the screen displays Yamaha release the top key.
If this doesn't solve the issue then it could be a number of things as the keyboard does a self check on startup and will hang if a fault is found. Check each rubber switch is not stuck down or even missing this can cause this issue. Please report back either way.

Battery problem. When using batteries, the keyboard shuts off without warning several seconds after it has been turned on or when the keys or buttons are touched. The keyboard works fine when plugged into...

Sounds like the connections may be oxidised. With a long, sharp knife scratch at the metal contacts at each end of the battery compartment until they are shiny,and make sure your batteries have good life in them. If that does not work there may be a broken wire connection inside, or, less likely, a short circuit has occurred that is draining the batteries (I doubt that though)

I am trying to install yamaha usb-midi driver software on my laptop powered by windows vista. getting this error 25001 (no device connected message). help please

I know this sounds weird, but make sure you connect the MIDI-OUT cable to the MINI-IN port on the keyboard, and the MIDI-IN cable to the MIDI-OUT port. Backwards and illogical, but there it is.. I had the same problem; now it works flawlessly.

Multi region player

DVD players come out of the factory region locked. You can either buy an player that does not have a set region (you can only get these online) or you can unlock the DVD player on a computer using software.
