Is laptop GPU dead?

[zaka100]

So I've got a Toshiba satellite l300d and I get no video. I replaced the mobo recently and I'm sure all the connections are fine but the monitor is not getting any power at all. I tried plugging it via VGA to my TV but I still get no video. Could this be a GPU problem? I dont see any physical damage on the chip so I'm not sure.

If you want the full specs then please ask

There is a possibility, but hardly it is the case. Why should be?
What is the reason if it is really the case?

Try re-seating the RAM, this is a common cause of "black screen" issues

Any lights flashing, such as power/batt/etc.?

1) Sorry I dont really know what you mean right there
2)hmm, yeah I gotta try reseating the ram. I have some spare ddr2 sticks that work so I'll also use them.
3) no, there are no flashing lights, not that I can remember.
