BGA Chip
February 8th, 2020
I have a broken graphic card it’s an nvidea 8600M GS thebscreen is black,
I’m thinking if It is possible to change the BGA Chip ?
In general, the problem of the broken graphic card is coming from that piece ?
Are you sure it’s the GPU and not the Motherboard/RAM?
Try removing all memory modules and powering it up, If it beeps, The motherboard is likely in good
condition, If it doesn’t, Then it’s dead. If it’s all good in that department, Then try testing the RAM out.
A faulty module can cause a black screen too. If you got 2 of em, Try each one standalone (As in with the other one
disconnected). If you only have one, Then you’re gonna have to buy another one in order to test it. Another possibility is a bad monitor or monitor cable, Most (If not all) laptops have an external display output (Usually VGA or HDMI)
so try connecting it to a 3rd party Monitor or TV and see how that goes (You would have to press FN+One of the F keys after you power it up in order to make it switch the output!)
If you’ve reached the conclusion that it’s indeed the GPU, Then your best bet would be to either reflow it or replace the motherboard (It should have a part number on it, Just look it up on Google or Ebay and you’ll find some sellers!)
In order to reflow it (Fix loose soldering joints) you could either use a heat gun, Or simply bake it in the over (And I’m being completely serious here!) it does work sometimes, Just see this example

Basically, You need to first disassemble your laptop and remove the motherboard (Look up the service/maintenance manual for your particular model on Google if you’re unsure how to do this) up next, Remove the round BIOS battery (As it can explode in high heat!). Use pure alcohol of 90% or better along with q-tips/cotton balls to clean up any old thermal paste from the CPU/GPU, Pre-heat your oven to 200C or 385F (Depending on whatever temperature standard they use in your country) Take a tray, Put aluminum foil on it, And also make a few aluminum balls (You don’t want the motherboard to touch it directly, So put it under the motherboard’s corners for some spacing) Anyways, Put it in, And give it 9-10 minutes, Turn off the oven, Open it up and give it an hour or two to cool off, Remove the tray, Put it all back together, And hope for the best! (Do note that you’re gonna need some thermal paste too for reapplying) If your laptop’s CPU/GPU cooler have thermal pads instead (rubber pieces underneath) better remove em before you put it back in, Otherwise the heat conductivity would suck. Generally speaking, You can either use paste or pads but not both at once. Thermal paste generally provides much better heat conductivity than pads however, So is always the better option.
In an answer to your original question, Yes, But it’s not simple one bit!
First of, Only a limited number of GPU chips would fit, And they wont be easy to find. And on top of that, You would need an SMD soldering rework station and a lot of experience in order to do it properly. So to sum it up, Baking or replacing the motherboard are your only practical options!
Thank you Roberto for all these details ! You are not a V.I.P for nothing dude !
If I press FN+F1 it will shows directly to the output without needing to pass by the control panel ?
And I think that the problem came from the graphic card, because it started when I move the PC the screen became black,
Then I cannot open the hinged cover only if I do not exceed an acute angle ! !
But after that when I open the PC, it starts but the screen remain black.
I founded an article that’s seems interessant, it describe the same method that you proposed !

Thank you again Roberto!
Thank you Roberto for all these details !
You’re welcome!

Thanks for the compliment.

Provided it’s the correct F key for the job, It should work OS regardless.
Speaking about OS’s, If you turn your laptop on and wait 2 mins, Do you hear the Windows welcome screen sound? And I think that the problem came from the graphic card, because it started when I move the PC the screen became black,
Then I cannot open the hinged cover only if I do not exceed an acute angle ! !
Are you saying the screen only displayed an output when you opened it slightly, But not when you opened it fully?
If so, This may indicate a problem with the inverter board or cable.

Here’s a lengthy forum discussion about it, With a lot of success stories and pics:

I’m sure you’ll find it useful.
Thank so much Roberto ! I’ll start by changing the inverter board ? I have a wreck amilo xi 2528 that I’m using for parts !
Thank you again Hope that the problem is not from the G.card
Good luck with that!
Just don’t forget to check the other things I mentioned too!
Such as trying an external display (3rd party monitor or TV) / Testing the motherboard (A healthy one would beep with the memory modules removed!) / The memory modules themselves (If you got 2 of em, Try each one standalone, If you don’t, Then the only way to test if it’s a bad module would be buying a new one!)
If nothing goes, Well, You still got the all mighty oven to the rescue!
Sorry for the late reply btw, Just been busy over the weekend.
