Backlight turning off, invertrer-boardinverter-board changed

Hi, my late 2009 iMac 27" is killing me. Display goes black 10 times a day. When I hold a flashlight to the screen I can see stuff on the screen. External Monitor works fine. Regarding to some other articles on ifixit, the backlightboard should be damaged.

So i ordered one from the US (I´m in germany) and replaced the old one... same failure *crying loud*.

Do you think i should change the backlight cable also? I can only find one on the internet and thats &##* expensive (more expensive then the board itself). Where do you guys get those cables?

Does anyone know why the display is turning off in such irregular intervals? Is it a heatproblem??

Maybe i should plug out the display-thermal-sensor-cable an see if it is still turning off?!

Thank you!
