912 Video Display does not work

Post by gawikoff »

I received a 912 NTSC/PAl display today ( Invoice 377663) intending to drive it with
an RPi. I applied 12v power, pos to red and neg to black and nothing happened except
the corner of the controller board near the connector gets quite warm. I tried pressing
the buttons but nothing. Using a Fluke 87 I measured the resistance across the red and
black leads and found it to be about 90 ohms both ways indicating a resistive connection
between them. This equates to about .133 amps, considerably more than the 80ma you
indicate the controller should draw at 12v.

Any assistance would be appreciated.

Hmm.. sounds like a known-but-rare issue that can occur with that display's voltage converter.

Send a note to [email protected] with a link to this thread and we'll get you a replacement.
