Having problems with your ViewSonic VA702B 17" LCD ?

My biewsonic va702b, when powered up flashes for one second the screen. it's bright in all the corners, just wont stay on, power light changed to orange. do I have inverter problems??


Answers :

The power light turning orange means the monitor isn't getting a signal from the computer. Or the monitor has a problem. If the screen shows light in the corners, the inverter is working. (If the inverter stops there is no light at all.)

The first thing to try is connecting another monitor to make sure your computer is actually starting up. If that monitor also shows nothing, you have a computer issue to take care of. Otherwise the monitor needs service.

Computer monitor I leave my computer on all the time and recently my monitor will not stay on. The power light is green (not orange for standby) but the screen is black. I can turn the monitor power on and off and it will come on for a brief second and then go black again. If I do this numerous times, it will eventually stay on. If I restart my computer it will sometimes stay on but not every time.

I have a Toshiba P305d-S8828 laptop. Over the christmas it stopped working. The keyboard lights up, battery charge light is on, main light is on but it wont start. Tried without battery(thought that was the culprit). The laptop is beyond warranty. The power plug is solid, so that is not the problem. The cpu fan powers up and then shuts down but the lights stay on. My suspicion is a power inverter. However I am just guessing. I have seen LCD inverter available. However I am just guessing.
