Acer Aspire 5735 LED screen with ccfl Converter problem ?!

I had a problem with my Aspire 5735 LCD screen and i was needed to change it. Just bought a LED screen not LCD screen and i used a ccfl converter to be able to connect with motherboard. I assambled very carefully and powered up. Worked very good for about 4 restarts and after that my laptop didn't powered up anymore.

Question: Does the ccfl to led converter interact in motherboard like.. burning something inside?

Thanks
