Probably a cable has come loose inside the unit. The keys are scanned by the internal processor as a matrix of two contacts per key. Often the keyboard is divided into two sections.
You will need to have it repaired or if you are electronically adept, open the case and look for obvious problem.

Some keys wont work after my korg pa50sd is turned on

It's about hardwares.
If dead keys are the same notes(C2-C3-C4 or E2-E3-E5 etc),its electronic parts problem.
If dead keys are random(D1-F1-G3-B5 etc),chances are :
  • Rubber keypads is break. Below the keyboard. Replace it.
  • Dust can cause bad contact the carbon inside the rubber keypad. Clean it.

Hi As recently as a month ago I bought a Kurzweil PC3K8 from sound solutions. On 13/08/2011 I took the keyboard (in a flight case) to a gig. After setting up the keyboard and powering on, the blue light...

Hopefully you didn't take it on a flight as sometimes they use bomb detecting equipment that subjects cargo to either high levels of radiation or high electro-magnetic fields. This can damage the equipment. It sounds like the processor is not running. There usually is a screen contrast control that can be turned enough that the screen appears blank, but usually you can get a sound out of the unit without reading the screen, Look in your user manual for a FACTORY reset or restore and pperform that procedure. If that doesn't work, then repair is in order. If unit has been vibraated during transportation, it is possible a cable has come off inside. Since you just bought this, EXERCISE you warranty immediately.

Casio tonebank ct700 no sound from chords only whilest on fingered chord please advise

More info. If you are chording on the left half of the keyboard, SOMETIMES they allocate or have the option to select a different voice for the part where chords are played. For these, you have to ALSO select a voice for that half of the keyboard. If you don't select a voice, then you would not have anything sounding.

Lcd only showing half on yamaha 600 keyboard

i assume you mean that, only half of your LCD is functional.
if this is the case, it culd be one or more of many things.

the most likely, is that the screen is cracked. this may be an "internal fracture" and will not be visible (you wont see cracks).

another, however, more unlikely reason is that the ribbon cable is partly detached. if this is so, you could get inside the keyboard your self (which WILL void your warranty).
this is rather difficult, and there is a high risk of damaging other aspects of the keyboard in the proses.

if it is still under warrenty, call up yamaha tech support and see if they are able to do anything for you.
if you are no longer under warranty, or would rather pay: find a local music (or electronics) store, and have them look at it.

How do I split a yamaha HS 8 IN TWO PARTS TO TRANSPORT

At the back there are 2 screws between the upper and the lower part and under the lower keyboard 2 screws also. Remove the screws and disconnect the headphonejacks under the lower keyboard, also the pedalconnection plug. Now you can lift the whole upper part from the lower part (preferable with 2 persons). The best way to transport this upper part is to put it in a sleepingback (just fits!).
Kind regards,
