I'm rebuilding an old HP Netserver 4D/66 LM and I want to reuse as much of the original front panel as possible. Part of that panel is a very small LCD sharp LM16X21A
. I found a pinout guide
, but it neglects to mention what I consider to be an important part. With the original setup there are 2 wires separate from the data ribbon that are labeled "LCD +5V". In the only guides that I can find there is no mention of those two wires and there is power going into one of the old data ribbon ports. In the picture of the LCD for sale with the harness it looks like there are wires running to those two solder points but the solder points from the data ribbon also look full. I am scared to hook anything up without knowing which of the two or both should have power. Does anyone have any experience with something like this?
On a side note for the project, I think I can use the original power and reset buttons, the power and HD LED's, and the system speaker.
