Re: 2.2" 18-BIT COLOR TFT LCD persistent white screen

I had a similar issue with my display that I just received. My display (the 2.2" TFT Display
320x240 pixels in 18 bit color with a microSD breakout) would randomly display a white screen, and I would have to reset my Arduino Mega a few times or reprogram it for it to work again. It would only function for a few minutes at most after this before the screen went white again. My serial interface was still printing information so my Arduino was still running correctly. I found that connecting the RST pin of the display breakout board directly to the Arduino 3.3V rail (and leaving it connected) fixed the problem.
