    (BTW: there are no flyback transformer transistor to fail in LCD. This is what used to cause the white light across tube TVs)

This problem is either the LVDS plug that plugs into the lcd display, or the logic panel, or worse case scenario the lcd display is bad.

What is wrong whith nabi 2 that has sreen probloms


sounds like your screen broke. Nabi has 2 'scereens' a piece of glass on top, then the LCD screen below. The LCD screen can be broken by hitting or twisting it. It can also become more prone to breakage if you leave it out in excessive heat.
Nabi will fix the screen for about $60...

see if the trc filament is light, if is not check the resistor that is serial whith the filament.
But the filament is light, turn a litlle the screen knob of the fly back transformer, may be you will see a horizontal line at midle of the screen, these mean vertical trouble.

The tv picture looks like should be wachting it whith 3d glasse


This is a very common failure on Projection TV sets. Its called a convergence failure. Here are some common symptoms.
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
The other common problem is cloudy lens fluid. After many years the coolant in the blue and green lens will become cloudy and cause the screen to look dull, red/orange, bright white, etc. You may even see halos around objects on the screen.

You can see some example photos and find a solution here on Fixya.
