The digitizer is the touch sensor which can be separate from the LCD display. If all you see is white then it could be just the back light working. I suspect the LCD is broken and as stated probably not worth repairing.

Well to be precise there is a gray line that goes down the middle of the screen on the short side. When it boots its light gray but after a second or so it becomes dark gray.

I'm concidering making it into a headless server, since I can get a generic ARM linux distribution running on it from the uSD I can get it to attach to wireless network at boot and then access it via ssh.

I can confirm that the rest of the hardware seems fine as I've gotten it to boot from a uSD with an ordinary ARM Linux distribution and I can access the device via ssh over a wifi link.

I wonder if this thing can drive LVDS screen ?
I might be able to get LVDS display off an old laptop

Nice but my that tablet has not hdmi output ... or I'd have already connected it to something with hdmi input (like a monitor or television).

Pity. There are a number of tablets that do have HDMI output, but if it's not available, I don't know what else to recommend. Some do allow video out via the headphone jack, usually called TVOut, by using an adapter cable with 1/8" plug to RCA plugs. I have owned a Samsung phone which did that. I don't know about your tablet, though.

I don't think that my tablet supports that ... as typically hardware that supports that has a 4 way jack instead of 3 way. Looking at the soldering on the pcb shows a standard ground, Left, Right and insertion switch.

Anyway by driving LVDS I intended if this device could drive an LVDS LCD PANEL ripped out of an old notebook from the output where the original display was connected ?
I guess the best way to get an answer for that is to google for the specs of the original display and try figure out what sort of connection it's using.

This is a picture of the original lcd label.

I googled for "BOE 070 REV D" and found this ... but after looking at the picture I realize that I should have googled for "REV.0".
After some better research I came up with this (KR070PE2T).
Anyone know what type of connection is that 60 pin flect cable ? maybe TFT ?

Looking at the cable connector. It is a zif harness usually used for hard drives and keyboards=(older laptops). Everything I search for from china with a title like "zif to hdmi" or "zif to video"

turns up harddrive adapter cables with pc boards.

Must be a communication problem between us.

According to this chart the A13 SOC has RGB LCD output and VGA output: how hard would it be to interface to a VGA monitor ?

The RGB output is also confirmed by Allwinner documentation here.
