The title pretty much says it all. Hewlett Packard LCD Model PE1229 from 2003. No power supply. I need to find out if it's positive center or negative center before I plug anything in.

Anybody have a Hewlett Packard LCD..or work on them?

Model PE1229
12V 3.5A DC (solid line over dashed line)
Chassis CBPC780K
Product # P9620A
Hewlett Packard 20555 SH249
model name f1703

I once had an HP one but now it is an ACER one. kekekekeke!

Solid line over dash indicates that it is DC and the inner one is always positive. AS far as I have seen.

You got an LED that you can fry ?

Sorry guys. No smoke, no pics, no problem. It has already been delivered to the customer and I'm back at home for supper in less than an hour.

Thanks for the help.
