I'm working on trying to get a TFT LCD up and running on a PIC32. It has an ILI9325 controller on board and I was able to get it operating earlier today. I had it displaying full screen graphics and text. I used some init code I found in a PDF document for another display with the same controller. After I got this board working, I left it powered on and went to solder another LCD to another PCB to get it working too. When I came back to my desk, the first LCD had gone white screen and I have been unable to get it operating again.
Is it possible that using the incorrect init code damaged the LCD somehow? Like maybe the charge pumps went to too high of a voltage or something? Whenever I power on this board and the init code runs, the whole screen generally flashes to a solid color (though somewhat faded) usually green though occasionally blue or pink and then fades to white over about a time period of one second.
I'm waiting for the manufacturer to (hopefully) respond with some init code for this display. I have a document that describes all of the registers but I've given myself a headache trying to decode everything >,<
