I have a more than one tft screen where the backlight shuts off after

The screen functionality for the TFT matrix seems ok. And because the
tubes actually gives light even if only for 2s I assume they work. And
conclude it's the backlight inverter pcb.

This pagehttp://www.hackaday.com/2005/11/01/lcd-backlight-replacement/
was my inspriation when I fixed my Sony LCD.
I didn't replace the bulbs, but I did use an external invertor PCB to
drive the bulbs. I used one from a cold cathode case mod kit.

I have considered this path aswell, but the catch is that then you can
no longer adjust brightness..
Any idea on how to solve that ..?
