Viewsonic vs12324 Monitor turns on briefly, then turns off.

It should with the vga cable it will be a small rca audio plug

Open it up and look for bad caps with bulging tops, also check for 12v for the backlight inverter circuits. See some example of failed Viewsonic monitors here: http://s807.photobucket.com/home/budm/allalbums

your monitor is burning out. if you just bought it, check the warranty.

hi. it sounds like the power supply has gone bad... try to purchase a new power supply cord..

thank u
rate me

it looks like the Inverter's gone in your screen, it works like a starter in a florescent tube, it 'kick starts' your screen to come on. Turning it on/off many times eventually 'kick starts' your screen and makes it come on eventually.

The light turning to orange means the monitor is not getting a signal from the computer. Check your monitor cable at both ends and make sure it is in very tight and secure at the computer end as well. Also check to see if the computer stays on when the light goes to orange on the monitor. The power cord for the computer might be loose.

Assuming this is a E70fB monitor
OSD Unlock : Press and hold the [1] and [▼] buttons again for 5 seconds. The message “OSD UNLOCK” will then display briefly, indicating that the OSD image settings are now unlocked.

Check your video card. Is your computer booting up?

Look for bad caps in the power supply.
