Casio WK-220: No power going to the device with AC adapter or batteries

Thu, 07 Mar 2019 20:09:45 -0700

I’m not able to turn the keyboard on at all by pressing the power button, with either (brand new) batteries or the AC adapter. I haven’t used this keyboard in at least a year, but it was working fine before then. I took apart the front cover and looked at the circuit board, but I don’t really know what I’m doing. There’s little to no dust inside.

Casio WK-220: Keyboard not starting when power button pressed

Sat, 10 Dec 2022 02:28:56 -0700

Was working fine until a few days ago. Always had a loose connection problem near the dc input but that used to be fine and it used to work after moving the power supply a little bit here and there.

Verified that the power supply is not the problem by connect the 9v dc input from the battery end.

Now whenever I try to switch it on the lcd backlight comes on but the keyboard itself doesn’t start. As long a the power button is held down the backlight is on but on releasing it switches off immediately.

For a few days the backlight would stay on even when the power button would be released and sometimes the keyboard would actually start and then go back to a COD backlight only mode. Now even that doesn’t happen

Any help would be appreciated
