Gateway Nv3717u not posting

[rda10002002]

I have a Gateway NV7317u that will not past post. It gives a blank screen and no external screen will work. The power light will light up and the HDD will spin up and stay spinning. But the fan will start then stop after a few seconds. The light on the power supply says a green light. I have the motherboard out and did not see any damage. Anyone have any ideas on how to fix or listing of chips on the motherboard that may go bad?

If it doesn't reach post it might be a corrupt bios.

reflow

Re: Gateway Nv3717u not posting

Nothing will display on the screen and no beeps are heard as if it was getting to post. And the reflow is the first step i tried and it is still giving the same issues. Anyone know if there is a listing of the chips and the placement for this board?

maybe a bad ram stick or ram socket
try one stick at a time in both sockets

I have tried a combo of 4 different ram sticks and I have tried a reflow on the gpu. It is the same no matter what socket the ram is in

This is the motherboard in question. The part in red looks like its damaged. Not to sure if this is leading to my issues

Re: Gateway Nv3717u not posting

Is there a way to try to reflash the bios with out getting anything on the screen to see if that may be it?

Hello,

With that ati vga chipset I would first change it and then check the bios.
Hope I've helped you.

Re: Gateway Nv3717u not posting

I figured it may have been the gpu chip, just have to find an easy way to remove it

Re: Gateway Nv3717u not posting

So I was testing some of the led light bars, and found out the touch media bar that allows for the volume to be muted or turned up and down will still work. seems like it may be the vga chip. Anyone know of an easy way to replace the chip on a DIY level?

use hot air gun

Re: Gateway Nv3717u not posting

I have worked on that before. Reflow will not work as two pins (balls) or more are touching each other. You will need to reball those chips. Since those chips are so thin, you need the right temp to remove and replace or else you will damage the IC.

Good luck!

Do you know of a good way for me to fix it from home. With out having to spend a lot of sending it to have the chip reballed?

[rda10002002]

Re: Gateway Nv3717u not posting

So does anyone know what size solder balls to use for this chip for a reball?

[rda10002002]

Re: Gateway Nv3717u not posting

Still not having any luck finding out what size solderballs to use on the gpu. Do anyone know what size is needed? And a good place to order them

Re: Gateway Nv3717u not posting

Hello,

It is 0.5mm the size of the balls. It is a rather cheap chipset if you want to buy it..
