Acer Aspire 5050 series no post ,vga

[fabiog]

Have this Acer Aspire 5050 laptop that when you switch it on the power leds stay on and fans spin and no post nor VGA image on screen and then it switches off.
Thinking it's a graphics problem I did a quick re-flow on the ATI x1100 chip and now when switching it on the power leds switch on and off in a second while before it would switch off after about 30seconds.
Something else seems to be wrong here and anyone with experience with this model or graphics chips would be helpful.

I have worked on those acer before and let me tell you it's not a video issue you shold start by making sure all your mosfets are working also check for bad diodes.

Thanks for your reply.
I will measure when I can but I think I need to heat it with a higher temperature as I don't think the temperature was high enough that I used.
