Sweet! I won the item on eBay and couldn't adjust the geometry or even keep a steady picure. This guide has the full schematics (not available anywhere else as far as I could tell), and was a bargain for the wealth of knowledge it contains. I hooked it up to my testing equipment, tweaked a few potentiometers and got it playing videogames in no time. Thanks!

It was just what I need to fix my old BMW's CD player. Very convenient also. Thank you.

When the STBY LED does not flash, the power supply circuit is defective.
2. How to find PDP unit trouble 1) The power voltage for the PDP is supplied correctly. The power voltages are supplied from the switching regulator board CN6, CN23, CN33, CN42 and CN52 to the PDP panel. The four types of power voltage that are 3.3 V, 5 V, 55 V and 80 V are supplied.
2) The input signal is supplied to the PDP panel correctly. The LVDS signal is supplied to CN1 of the circuit board in the bottom of the PDP panel. (CN1 pin-1, pin-3, pin-5, pin-7, pin-9, pin-11, pin-13, pin-15, pin-17 and pin-19) If no images appears through the above conditions are satisfied, the PDP unit will be defective. 3-1
