LCD not working after ssd installation


Hi there,

after succesful installation of a ssd, I damaged display data cable and afterwards the the lcd of my imac stays black. Computer is booting and running normal, an external display shows picture.

Diagnose LED4 stays black, all others are green.

I already bought a new display data cable and a new backlight inverter board but both with no result - the lcd stays black.

No i´m wondering what it could be, because I don´t want to buy a new lcd if it´s not necessary and I already spent a lot of money with no result.

Every help is very much appreciated.

Sorry for my bad english, I´m from germany ;-)
