Hello folks, i'm lost here !
I have got a bunch of lcd's from a friend. they're originally meant to sit in an GPS-unit. these are replacements-screens, and were sorted off as scrap. some has deep scratches, others defect CCFL and so on. now i have built an working LCD with the parts. the LCD has no controller, but has pads for an T9363C, so i mounted an controller with ram, oscillator and caps (removed from mechanically defect DMS5003) all is good, i can get the whole display white/black by varying the negative contrast voltage. the lcd was DEAD before i mounted the controller (e.g. no pixel response when applying power)
So SOMETHING is going on between the controller and the driver LSI's.
What have i overlooked ? i have traced the traces with an DVM from the pads to the 20-pin connector, and it's connected the right way. i have triple-triple checked it !!!
The LCD is an 240x128-type. i have tried all settings in LCDinfo - no joy. my artillery of different LCD's and VFD's work just fine.... i am using LCDinfo V. 0.6 (Build 18)
Advice anyone ???
I have shot some images of the LCD with / without the controller mounted. there is an video too, that shows what's happening when i start/stop LCDinfo....
