If you specified to run the video check multiple times, this
menu does not display and only the first test (Video adapter
check) is performed.

If an error occurs during any of these tests, record the error

code and message, or print them out. Then contact your Epson
dealer.

When you finish running the video adapter and display

check, press 0 and 

Enter

To check the video adapter, press

The computer checks the video RAM (display memory) on

the 

display adapter by writing test data to memory and then

reading it back and comparing it to the written data. The

computer also tests the video enable signal of the display

controller chip.
