how come my toshiba p35-s611 lcd screen does not come on. I just put the computer back together after cleaning the fans and heatsink.

How come you just needed to put it back together?
Did you connect it to the IGP or the GPU? Does it even boot up?
Did you power it on?
Like a zillion unanswered question....

It does not boot up. It starts and the lights are working, but nothing on the screen

if it does not boot up, that means the computer is not starting, recheck all the wires are properly plugged in on the mobo.
