    did you find anything out on this? Mine is the same, but i have went as far as to replace the power supply completely. There seems to be a short on the display board. The 3.3v regulator and the crystal are both working on the display board. Let me know what u did with your unit and if you ever got it working.

You need to try it with another PC first, but more likely to be bad caps in the power supply section inside the monitor.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Never turns on, power light flashes fast


The flourescent lamps on the sides of the LCD panel is burnt out. If you open the monitor and look at them, I will bed they will be blackend on one end. This is common and you need to find some new ones to replace. They are usually about $15 and plug into the HV little board that drives them. Hope that helps!

Envision H22W monitor will not turn on, light flashes


check for the source if connected, the vga cable if properly hooked up to the port. if ok then still display wont come on, unplug the monitor and then locate the power supply board of the monitor and look for a bulging electrolytic capacitor which is common problem of lcd monitors.

How do you take the base stand off of an envision 22in lcd tv? I want to mount it to the wall?


There is a screw on the part of the base where it connects to the monitor back, it is located on the pivoting arm, remove or take loose this screw and lift the base by holding the side opposite the screw. the base should lift off with at very most just a bit of wiggling. You can now use the wall mounting screw holes located under the corners of the sticker on the rear of the monitor, they are usually covered with a perforated area.

Flashing light nothing else


Doesn't sound like a virus. Sounds like a fuse or something else is out. A red light isn't good. If the monitor is ok you get an amber light. I would suggest this monitor is gone. Sorry.

Envision EN7410e monitor


Just fixed mine. Maybe it's a few years late. Hope you guys still have the display. It's the power supply board. I've just replaced 4 bulge capacitors near one edge of the PS. They are 2x1000uF 10V, 1x470uF 25V & 1x470 10V. I salvaged my parts from an old CRT monitor. Hey you can go green with your repairs too!

Sound


Check if the sound is enabled on your PC then check for wiring that goes to the monitor.

Do you have more information or questions?

No Sound on Envision H22W Monitor


The Envision H22W has speaker grilles, but does not include speakers. Note there is no input connector for audio.

The Envision G22LWK does have built in speakers. I think they just used the same mount/frame for both models, but only the G model actually includes the speakers.

Note that the web specs and the manual for the H22W says nothing about speakers.

No doubt this is why the H22W costs appreciably less than the G model.
