I have a HP Touchscreen that belongs to a customer. I believe the power supply has gone out and have already placed an order for a new. I decided to do some reasearch and test the pins at home and nothing seems to be the correct voltage.
I cannot find a pinout anywhere on the web. It is a non standard 18 pin setup.1-4 are yellow, 5+6 are blank, 7-8 are black, followed by green then purple. 9-13 are black, then grey, black, blue and then pin 18 is black.
So far the voltage readouts are all around 3.5 volts, nothing registers 12 and I belive one pair measured 5. I need to know if this is bad so I can cancle my order and save the client and myself some time. The order can be returned, I made sure of that but I am 90 percent positive its a bad unit. The strange thing is when I removed it and plugged it in the green status light came on. Now I am neven more curios and have spent literally hours searching for a 18 pin hp pinout, the closest Ive come does not even have the same layout and is different colors for different pins.
Please help.
