Display Problem with my D900t (Area-51 m7700)

Ok. Here is the problem with my Easy Bake Oven,

I started to have display issues like, little green, blue and red dots appeared on my screen in various places. A week or two later the dots multiplied everywhere and after time the screen would flicker on off on etc. I had to reboot or catch the arrow when the screen was up and reboot via the start menu. Once rebooted, it would function fine for a bit then happen again. This was all happeining while running on AC power. I discovered later after the laptop had cooled, it functioned better and had less pixel issues which ruled out a bad screen. After running for a bit and the pc heated up, the pixel issue and fliker came back.

After doing some research, I tried running it on battery power instead of AC power and discovered it lasted longer.


Now, the problem is real bad. The display flikers bad, log in screen is hardly readable, desktop screen won't boot up fully it seems, screen flickers and then blue screens shutting down "to prevent damage". Window screens hang up.

I can't do anything with it at this point. This is all happening now on just battery power.

I cleaned the entire thing out. Reseated everything. Checked all the fans and they work.

I thought that the graphics card (6800) was the issue, but after doing some more research, I discovered it could be the MB and that these graphics modules rarely go bad.

Can anyone give me some input on weather it's the MB or GC? I know that the MB's are cheaper so not being happy about this at all, I would rather it be the MB.


Help Please!

 

Welcome to nbr,

I think the problem is one of two things. Its either your graphics card artifacting, or their is a connection issue.
I have a d900k, which is almost entirely the same other than the motherboard.

If the amount of jitters on teh screen is random, than most likely it is something variable, like a loose connection on the back of the screen.
To fix this, you need to shut the system off, flip the system over, and remove the three screws which hold the battery in, and than proceed to taking it apart. It is important that the power sources are removed, so that you do not get shocked, or accidentally turn it on.
You will see small round rubber dots along the perimeter of your lcd lid.
You need to remove them, than once they are removed, you need to use a small flat head screwdriver to remove the screws which are located underneath the small rubber pieces. When removed, the screen should come apart into two pieces. You may need to use a small flat head screwdriver to help separate the two halves of the screen.
Than when you get the lid apart, you will need to remove the screws which hold the screen in.
Your goal is to get to the back of the LCD.
You will have to remove about 6 screws to get to the back of the LCD.
Than when you get to the back, you will see a gray cable, which plugs into the top of teh screen. Their should also be small yellw strips of tape holding teh cable in place.
Remove the cable from the port on the back of the LCD, than you need to clean the conenctions.
Use some rubbing alcohol on the end of a q-tip to clean both the male and female parts of the connection. Than when the connections are dry, reconnect them.
When you are sure that the cable is connected properly, use some electrical tape to tape the cable in place (use tape to connect the cable physically to the lcd)
Than put everything back together and see what happens.
One of three things will happen:
1) the problem will be resolved.
2) the problem will still occur (meaning its the graphics card)
3) the screen will not come on (meaning you may have forgot to reattach the lcd inverter, if you unplugged it) The lcd inverter is located underneath the lcd, so you may need to unplug it.

If the problem still occurs it is your graphics card acting up.
The graphics card is removable, and upgradeable, so you can replace it. It is just rather expensive to buy a new one.
