HP Pavillion DV9700

PopIT

Hey All,
Got one of these machines with a faulty screen. I also got a HP G60 that was liquid damaged.The G60 has I think a 15" screen and the DV a 17" screen. Is there a technical reason why it wouldn't work to fit the screen from the G60 into the DV or would it be just the fact that I would have a smaller screen?

Is there a way to tell if the screen is actually damaged on the DV or could it be possibly the back-light inverter that needs replacing, or some other technical issue on the motherboard? The screen itself does not look damaged in anyway.

Thanks for any help.

Just found this. http://www.nvidiasettlement.com/ Would appear it is a knowen issue with the Nvidia GPU but the bad news is that nothing can be done as it is outside the extended warranty of March 2011.

What you mean- nothing can be done?

Well what I mean is that HP or Nvidia wont do anything. HP will if I pay for them to do so. In saying that I could buy a replacement motherboard for around €120 (reworked) or pay to have a new GPU installed which as far as I can see would probably cost as much. I have heard of re-flowing, not sure what it entails but have also heard it only lasts a couple of months.

Would love to hear any other suggestions. Quite possible there is somthing I can do but not willing at the moment to pay out a huge amount of money. Pity as well as the laptop itself is pretty decent.

What exact model of of your laptop is? Or maybe you know what is the symbol of your nvidia chipset?
It is not surprising me that hp and nvidia don't care about customers. Nvidia just flooded the market with failed processors.
you considering to buy reworked mainboard for €120. Right, but one thing you have to know- you will get mainboard with the same time bomb. Mainboard will be reballed or just "reflowed". In your case, if this is really nvidia issue (could be some other reasons), you have less than 30% chance that your laptop will be "fixed" for over 2 months after reballing.
I will try to explain you this. GPU core (silicon peace in center of processor) is built like multi layer sandwich. This layer basically loose connection (crack) [nvidia revised chipsets after 09]. If you do reballing, you heat entire chipset, and connection goes back for a short while. Strip your laptop and heat up just the core with 240 Celsius for one minute (using hot air soldering station not the heatgun). Viola! It's working! That's why there is so many extremely stupid "solutions" around the internet like:
put mainboard into the oven
use heatgun/ torch/ candle/ spirit etc..
Why it's so risky? Because, if you heat mainboard in one point, PCB will fold, because of deformation other BGA parts may get balls cracked. If you don't use specific profile to solder element (is it hot air or infrared), you have great chance to damage GPU and PCB (stratification).

Now I will tell you how pro repair looks like:
Ever step, inc strip the laptop need to be done in electrostatic free area (ESD).
Mainboard is stripped out with all devices, all foil stickers plastic goes out. Board is mounted on preheater, that heating area can not be smaller than pcb size. Typical profile looks like this- pcb is heated from bottom to 180 Celsius in 3 minutes. Then temp goes up (top heater) to 220-230C in next 30sec, stay with this temp for 15sec and this is time to lift the gpu up (now cooling profile is initiated). Now it's time to clean the pads on pcb and chipset (if reballing is required). Then you solder it back

Sorry if I'm getting you bored..

My point is- if you want to have this laptop repaired (and this is nvidia failure), you have to replace it with brand new part manufactured after 2009. And there is a catch if you will go on ebay, you will find reballed chipsets for around €20, and "brand new +10" for €70 or more. So where is the catch? there --> "brand new +10" usually these chipsets are refurbished by polishing core, and print new data code on it. Sometimes you can find auction with Real brand new nvidia chipsets, seller has 20 chipsets available and suddenly somebody buy all all them.

If somebody offering you nvidia chipset replace, and if this is real new chipset, then you should expecting of one year of warranty for repair, but it will cos you around €160-190 depending of chipset model. Part will cost usually half of price you pay, rest is labour. If you think that labour is expensive- chcek prices of equipment need to be use.

PS: There is something to read if you want to know some more about "nvidia failure" http://www.theinquirer.net/inquirer/news/1050052/nvidia-chips-underfill

That's exactly what I wanted to know. All my options in one well explained post. At lease now I can take a look and see exactly what my options are.

Many thanks.
