Casio CTK-651

Hi Guys,

Any reviews on the Casio CTK-651?
I saw this keyboard on sale but there's a problem to it.
Whenever I increase the volume and press a low bass key the LCD screen will flicker and then shutdown by itself. Any low bass sounding keys
But when i output it to my guitar amp or power amp, no flicker or autoshutdown.
Is this cause by it's integrated dual speakers?

I sounds to me like a power supply problem. The internal amplifier is probably drawing more current than the power supply can deliver. Are you using the original power supply? The original Casio supply delivers 1.2A. If you are using a different supply, make sure it is 9v and at least 1.2A (1200mA). Alternatively you could try using some brand new batteries.

Could be.
Cos the adapter is not Casio.
It's a 9v 1000A.
But I check the back of the keyboard and it shows 9v 800A.
Should be more than enought right?
