Question about ViewSonic VX2235wm LCD Monitor
The power light stays on even though there is no picture. It never stays on more than a second even if I turn the power on Monitor off then on again it will flash a picture then go black.
Your monitors backlight is shutting off due to a failed component. The inverter circuit which drives the high current CCFL backlights, has a feedback design so that if there are any problems with the devices along the high current path, the high current will shut off. This way if something got shorted out, it would not sustain or cause any great harm. This is a great feature if you are the "short" in the circuit.
So in actuallity, your monitor is still on, and it's still showing you a picture. You just can't really see it because the light from behind has turned off. If you take a flashlight and put it up close to the screen, you'll see your desktop again!
As to what is causing this, It can be several things.
-A broken or burnt out CCFL
-A bad capacitor in the power supply filter or on the inverter.
-A shorted out IC.
-A mouse has crawled inside your LCD and chewed the CCFL wires. (this usually is accompanied with a high pitched squeeling sound, and/or smoke)
You can send me the entire monitor and I will repair it for $40. You pay shipping costs BOTH ways. Let me know if you're interested and I'll provide you with more information on where to send it.

i have read some reviews on your monitor
So the ex-hubby calls me with his woes - his eMachines T3124 is having problems. Seems that when he cold boots in the morning it hits the "E" splash screen and then just goes to black screen. No bios boot screen, no boot to windows. Everything sounds ok though. After a few restarts it boots ok. So, first trouble shoot is to replace the 180w Bestec power supply with a salvaged 300w Hippro from my T6420 (which was replaced with a 500w) - the one I replaced the mobo on. Works great ... for one night. Next morning I get the frantic call - now he gets nothing after the "E" splash but white wavy lines, but the computer sounds like it's running fine. Ok - ok ... think, think. First thought was maybe the onboard graphics have gone, next thought maybe the mobo is going ....
What is the next thing we do after trying a known, good power supply? Try another working montior. I had him try using a trusty older CRT monitor and Wha-Lah! After less than 3 years the E17T4 LCD monitor had failed. Most recent crisis handled. This little incident has made him realize though that he needs to burn all his picture and videos to CD. Scared him to think he could have lost them. Today's reminder? BURN your pictures and videos now! You never known when something might happen. And eMachines monitors are ****.
hope this helps
