My t999 has a major screen issue that I haven't been able to find described in multiple searches. First, it flashes blue when I turn on the screen. Second, every other line seems to be muted gray, which leaves everything looking crappy. Whites are duller, blacks are lighter, and text especially small fonts look like something from an apple IIe. At first, this would only last a few seconds after powering on- the screen would correct itself from the top down in chunks, sometimes leaving faint horizontal lines that would fade. Lately, it's taking longer and longer to correct, sometimes the brightness has to be pushed up or down to get this cleanup to kick in. Then, turning it off always brings it back to the muted gray state. I've tried forcing GPU rendering, dither options, even a factory reset and a change from stock rooted 4.3 to slimbean 4.3. These haven't helped.
The phone's history is messy. A wine spill shorted the USB port, then a firm brick had me send it out for port repair, which didn't seem to work, so I ebayed a replacement motherboard.
Any ideas? Thanks!
