Power supply problem on touchscreen contoller
wrote in message
...
I've checked on this and this is what I found.
The original power supply is proving 5V - 2A, +12V - 0.3A, -12V - 0.2A
While the replacement power supply 5V - 4A, +12V - 2A, -12V - 0.5A
Has the common ground of the +12V and +5V effect on the -12V in anyway?
Well the new power supply seems well capable, so either there is something
you have missed common grounds, or perhaps its the power up sequence
that might be wrong, and the various devices are not communicating/booting
together properly.
Dunno.
