Alienware M17x - Red pixels all over screen

Hello Tanzy,

It seems a problem to be with the LCD,
I would suggest you to run the LCD BIST (Built In Self test) and check if the red pixels appear.
To run the LCD bist follow the steps mentioned below.
-- Shut down the computer.
-- Press D+Power button to initiate the LCD Bist.
-- Check if the red pixels are seen on the test.

Please refer to the link mentioned below for more details.

Please write back with results.

Hi Allan,

Thanks for the reply. I have tried the test and surprisingly the tests went well. I don't see any red pixels on the coloured screens. Once I switch the computer on, the red pixels appear immediately though.

tanyz89,

Please connect an external monitor to the laptop VGA port. Do you see the issue on the external monitor?

Will it work if I connect it via HDMI to a monitor screen/TV?

I tried via HDMI cable to a television screen. It appers fine on the TV screen. The red pixels are still on the laptop screen though. Please help. Thanks.

It is either a faulty LCD panel or the internal cabling connecting the LCD to the motherboard. If out of warranty, you should get a local technician to reseat the cabling as the first thing to test. They will need the service manual for instructions. If reseating the cable does not fix the issue, replacing the LCD panel would be the next step. I will need to know your service tag number (via private message) to give you part numbers.
