Hello, I am having a very strange problem with my screen looking scrambled with a test pattern when I turn it on. It does not boot anymore.
When I hold down the D key to do the display test, it actually flashes white, red, green, blue, and seems to pass the test. Does anyone have any idea what's wrong? Anyone ever seen a screen look like this?
When did the issue start on the system? Could you kindly check with an external monitor?
Turn on the system by holding the "fn" key + power button and it should start the diags on the system. Make a note of any possible beeps that you might possibly hear. The exact # of beeps in a cycle will help isolate the source of the issue.
Based on your description, I would suspect a faulty video card and the motherboard needs to be replaced on the system.
