Re: Envision LCD monitor

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.

I have a KDS 5ms model 900W this was never used as my sister gave it to me since she was unable to get it to work. but like the others it won't stay on for more then 7 secs and you need to push the power...

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, I may be able to tell you more.

Turning the power on causes the screen to display ENVISION for approx. 1sec.and it goes out and stays out. Switching a display signal on through an A-B switch gives approx. a 1sec. display time that does...

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.

Probably blown capacitors, the 19" widescreen uses 6 16V 1000uF
Do you have a soldering gun? Its not that hard to fix, get the capacitors on ebay for $6-$8 with shipping.

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.
