Hello all,
I have a bunch of m2008's aries1 that have been refurbed. The problem is that none of the displays are working although when I plug an aries2 in the same port it works no problem. I've tried a few things, like using a power supply in the port to see if it would power the diplay. They came back with a 16 to 14 pin conversion card for the display so I tried a 16 pin display still no luck. There is a large daughterboard that I removed and used bridge clips on pins 6a/6b and 7a/7b to see if that would do the trick but to no avail. The Option 11 sees the phones as having a display but there just not getting power. Sorry for being so long winded but I'm at my wits end with this.
Any thoughts as always would be greatly appreciated.

I think the 1st ones took an external power supply & you do need the power board back in them.

Thanks JimmyT, any idea what the voltage and milliamp rating was on those.

JimmyT, you were absolutely right. And to answer my own question, the power supply that made the display work was a
Sino-American
120V 60Hz 26.7VAC 700mA 35W Model 57C-6
P/N AO367335. JimmyT thanks again, I really appreciate your quick response. Damn, this forum rocks.
