Thread: LCD Specs

Hi All

Here are the pics of the LCD, ave got a crap camera so they aint great, hope they help though..

Hi all

Anybody have any joy with identifying the details of the pinouts?

Not a joy, but sometimes neccessary...
To identify the power connector is quite easy. You need a cheap multimeter ('connection' beeper is an advantage, othervise measure resistance, under 1 Ohm is connected)

Most important is the ground. The large metal (often covered with isolator resin) parts on the PCB. The housing of the LCD itself is ground.
At least one pin must be ground and I strongly believe the shielding of the connector also connected to ground.
Next is the power (I suppose 12V, but is can be different). The location, where the cord is connected to the PCB, there are printed wires on the PCB. The thickest wire (which is not the ground). Try to find a stabiliser IC (7805 or so) and the input is power. Often protected by a fuse (marked as F1, F2 or so on the PCB).
When the power and ground are present, the monitor must show a sign of life (at least a LED is lighting in red or green), and after pressing the power the backlight usually switched on (at least for a bliss).

Other wires are signals, so there is not a huge danger to misconnect them.
Guess. Keep the ground-ground connection between signal source and your monitor!
Those signals often have check points on the PCB (small silver METAL dots - not covered with green resin) and there are 'speaking' titles in white (AV_in or so).
