Having problems with your Computer Monitors ?

Viewsonic E90 no display

\015 CRT when turned on showed display then went blank. Looked at inside and saw no blown parts, so re soldered and then assembled and was able to get screen to be seen. Once I turn monitor off then back on to test no display but heard the clicking sound and hum of monitor coming on and no display but a while dot light in middle of screen then goes out.\015

Hi and welcome to FixYa,

The single dot is significant as it indicates that the vertical & horizontal deflection circuitries would have to be checked.  Initially, verify that the 4 pin connector going to the yoke is plugged into the board securely.  The yoke itself may need looking into.

Good luck and thank you for asking FixYa.
Try a different moniter to see if it's the moniter if it works the moniter is out if not it's the video card. I had the same Viewsonic and it was a dream never gave me a problem. Hope this helps.
