How to remove the cover from a VA902b monitor

The "sleep mode" is probably set too low.. or a "power saving" mode is set too cut off too quick..(sorry for the low information) .. I am at work on an Apple.. geeezzzz :(

power supply on your monitor is not stable. Could be 1 of the ballast transformer of the backlight in the monitor is overheating and soon to burn out, that cause the instability of the power supply.

yes.....you need to install the driver for the AGP card from which you will connect the second monitor....

Please look at my pictures here: http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20VA721/

It is alomost the same as 902.

Mkae sure to use good caps such as PANASONIC FM or FC series from DIGIKEY.

Any PC repair shop should have this standard VGA DB15HD cable. Or just go online, it is just VGA CABLE 15-PIN/3-ROW male to male.

That is a problem of inbuilt display card it does not support to games. You have to open the system case and install AGP card in the AGP slot AGP card is available in any shop of computer your other problems will also solve

More likely to have bad caps in the power supply, that is the first place to check for bad caps with bulging top, it can also be bad inverter circuits, or bad lamps, open it up and post back what you see so we can guide you further, see example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

you have to repair your powersupply
replace 3 elec condensator 1* 22uF/40V and 2*470uF/25V this is placed in the erea off the PS light tubes

The problem can be in the backlight inverter circuits, look fo bad caps with bulging tops, look to see if you do have 12vdc feeding the inverter circuits. See some examples of failed monitors here: http://s807.photobucket.com/home/budm/allalbums

Check your MAC's standby, power and screen saver settings
