You're right--it is either screen or board.

No choice but to rule out screen with a known good LCD.

I have seen this kind of thing before---but usually it would be post-drop damage or water damage.  Never out of the blue.

A bad LCD will behave like this, but so will serious logic board problems.  I have seen both.

The chiming is typical---iPad yelp like that when they have a backlight problem, and knock it off when the problem is fixed.  Sometimes it is the device prompting you to enter 'trust this computer' on the screen.

If I were you I'd take it to a local shop and ask them to slap an iPad 3 LCD on there and see what happens.
