Faulty Hp graphics, screen green blank??

Here we are school holidays, days from Xmas and my luck both the kids laptops have failed with screen problems.

Toshiba A200 Model SAF3A-0QH01N
screen boots up loading page fades and goes blank!

Very hard to determine which graphics card it runs and if faulty whether it can be changed out or upgraded? perhaps it is not the graphics card?

Also have same problem all sudden on a HP DV9514tx sn CNF73678NM, part num: GN431PA#ABG. This i believe is running a nVidia GeForce 7300 GT 256MB GDDR (DVI/DVI) (PCI-E

Also have same problem all sudden on a HP DV9514tx sn CNF73678NM, part num: GN431PA#ABG. This i believe is running a nVidia GeForce 7300 GT 256MB GDDR (DVI/DVI) (PCI-E but cannot be sure?
If ca anybody please tell me if it is it is interchangable. I can buy a GeForce GO7600?

From everything I have read it seems particularly the Nvidia cards have faulty glue prone to heat probs?
Trying manufacturers sites to determine exact build card sets?

If anybody has info i would be very pleased thanks??

 

I believe those GPUs are soldered onto the motherboard which means you would have to replace the mobo in order to fix the problem(s).

 

Most likely your computers are fine, the GPU has broken away from mobo due to overheating causing the connections to crack. As I wrote in other thread about dead dv9500 display, there is a cottage repair industry for reviving HP DVxx00 with dead graphics by taking them apart and heating the GPU to remelt the connection, and enhancing heat dissipation. If you can't find a local repair shop to do the job, you might try ebay (though i personally haven't used ebay services)

Also, tell your kids, don't ever use laptop directly on soft surface, like bed or pillow, because it will cause overheat and premature death to laptops.

 

Thanks for that, I brought the part and am going to strip it tonight. Sounds bleak eh, will confirm to you later

 

Thanks Dacher will find a fix as described.
