Laptop No display problem

[calvincross7]

I have a toshiba sattelite l510.

I did not use it for 2months and when i tried to turn it on it boots up but shows no display at all.

**I tried to replace the ram with a working one
==>Still no display

**I tried to connect it to a working external monitor
==>Still no display
==>Message on screen is "no signal"

What could be the culprit here guys?

1. Does it have a video chipset that is directly soldered onto the motherboard?

2. do you get any beeps if you completely unplug all the ram?

1. yes sir, video chipset is embedded on board

2. yup it beeps when i remove the ram
