[Q] Dead screen now dimmer with vertical lines / banding
Hello. The screen on my wife's S4G today suddenly started acting funny. First, it wouldn't display anything, but it seemed the phone was still functional. Then, with fiddling on my part, I got it working again, first fully and now in a sub-par way. The phone boots fine - and I actually unlocked the bootloader and rooted, and in the process went through a full reset, just to see if that would help anything - but the screen appears dimmer than before and there's vertical banding across most of it. The banding doesn't completely obscure the screen, but it looks bad. One other thing I notice, and this is reported in other places, is that there's backlight bleed in the lower left corner, even when you just insert the battery, and often on booting, there's a flash of pixelated "dust" across the screen, that's brightest in that corner and fades as it spreads out.
Anyway, TMI probably. Does this sound to anyone like a bad screen, bad connector, digitizer, or something else? I'm totally new to any of these kinds of issues, but would like to save the phone, if possible. TIA.
