DETAIL:

A limited number of 8512 color displays may fail, causing a 2401 error during Power-ON Self Test (POST), or a 2402 or 2409 error code when VGA Advanced Diagnostics are executed. The problem may also appear as flickering or changing colors on the display during use. These symptoms may be very intermittent. A 2401 error code can be bypassed in most cases by pressing the "F1" key. Subsequent operation will not harm the display or system unit.

2401, 2402, 2409, and 2410 error codes may be caused by either a defective display or system unit planar board. The following symptom and action chart will help to minimize unnecessary replacement of the system unit planar board. 2401 is a POST error; 2402, 2409, and 2410 are Advanced Diagnostic error codes.
