My sister is having problems with her monitor on her Gateway 400 Celeron. When she turns the unit on, the monitor power indicator light will first turn green. Then, the monitor will display the “self test” screen, click several times, and the indicator light will turn yellow. I told her I thought this was a bad monitor but she put her husbands monitor on and got the same results. This was after trying a different electrical outlet and double checking all connections. The video/sound is onboard in this particular Gateway so I am afraid that IF it is video related, the motherboard would need replacing. She is bringing the unit down this weekend for me to look at.
I would appreciate any suggestions.
Thanks,
Jeff
