Did you check CCFL lamp?

What you mean put new LCD? Just LCD without backlight and other parts?

CCFL and inverter works then. Did you open LCD panel completely and see that CCFL have light on full lenght?

 

[sivakumarkollam]

first time ccfl is not work so change inverter..not get light. after i will change lcd 15.6.. not get result

Does LCD screen showup any picture? Did you try to light with some handlamp? Or best is to open panel and from back side to use handlamp.

If you dont have anything on LCD screen then look motherboard VGA section.
