Targa Visionary LT3020 starts ligth then dark after 1 or 2 seconds

[fpsousa]

Hi, Merry Christmas to all!
Now I have for repair an lcd "Targa Visionary" that starts, makes a flash light during about one or two seconds then stay dark, but the sound stays ok and the video comes out from 21 pins (euroscart).
The front panel led is green at first, then goes red blinking and finally goes off.
PSU produces 12V, 24V and ACdet at 3.5V and the 5V ST-BY.
May be is the inverter.
Any help?
Tanks.

Well, i-ve already detect one CCFL transformer with his secondary giving diferent resistance comparing with the other ones.
So, it seems to be this component.

Hi, folks,
Success, really was the CCFL transformer broken.
Whit a new one the LCD works ok.
The protection went into action.
