I recently received a none working datahand keyboard model DH 200. The keyboard consists of two separate key pods, a cpu controller and a power supply.
My problem is that it doesn't power up. No lights come on and the keyboard is completely unresponsive.
The power supply is rated for 5VDC @1.5A / 12VDC @ 750mA 100/240VAC and uses a 5-din connector. It will make a faint high pitched whine when I plug it into the controller. I tried to multimeter test it and it gets a little over 6 volts. I have made sure that everything is internally connected and nothing smells or looks shorted as far as I can tell.
I have noticed that I can get the keyboard to light up if I play with the 5-din connector by partially plugging it in at an angle. It seems like the PSU is working because of its reading on the multimeter but I am not sure as I am an electronics novice.
I attached a picture of the setup hoping it would help.
