Most likely the 2 470uF capactitors in the power supply have leaked and partially shorted. If you have those replaced it should power up fine. The symptoms will be the green power light will come on and the backlight tubes will light up for about 1 sec then the entire monitor will shut off.

I have an Envision G22LWK 22" LCD monitor that keeps turning off every 30 secs. How can I stop it from doing that?


is it turning off or going into sleep mode? If turning off, you have issues with the power supply. look at it and see if any capacitors are bubbled up on the ends and replace if you see this.

These have problems with burning up transistors on the inverter side of the powerboard.
Sometimes they are fixable, sometimes not. It depends on which board is in it (they used 2 different styles)
I have done a few of these.
If you can open it up and send me a picture of the board to bammbamm@ptd.net, I may be able to tell you more.

Your power supply has burnt out which unfortunately is extremely common in new devices. I do agree that it may be worth fixing if it is only couple years old.

The monitor turns on and connects to my computer then turn off but the power stays on. any ideas?


Make sure the external VGA port on your laptop is enabled. Not all laptops automatically detect a monitor connected and turn on the port. There will be a function key somewhere on the keyboard to control the port. Location varies by manufacturer and model. The usual sequence when you press the key is: laptop display on and external VGA off, laptop off and VGA on, both on.

Monitror keeps cycling through on-off


Found one of these in the dumpster at my shop today. Had the "stays on for 3 sec then turns off" issue. Problem is the bad batch of electrolytic caps of a few years ago. 2 on the power supply board were visibly swelled up (470u/16V and a 1000u/16V). Replaced them both - it's fixed. Cost 50 cents.
