HELP R50e screen works, but no backgroundlight !!

Hello !  

 

 i bought a r50e and tried to repair it. i bpught a new tft , works great, but there is no background light. the light is working , i tested it with another inverter from a differant laptop .

next step, i changed the inverter, without success. the led s on the inverter are working, so it it is connected with power supply. but for some reason it stays dark !   Could it be that the tft cable causes these problems ?   thanks for help !     Greetings simon

You may have a motherboard problem. That would be my first guess without knowing more.

 

My second guess would be to check if the correct LCD cable was being used.

 

Does the machine display anything on external monitor?

 

Good luck and let us know.

Cheers,

George
