Usually it's because it doesn't detects the signal. Check the cable and the pc. User manual

My Envision LCD Monitor screens turns gray once its power on. I have tried changing contrast will not work.


When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Good luck!

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.

Out of Range


Your horizontal should be between 30k-80khz while vertical should be 50-75 hz. So you are definitely too high. I would check supply voltages and open it up and look for any obvious issues with capacitors.

When i turn on my monitor (Envision G22LWk) it will go blank about 1 second after I turn it on. What might be the problem?


You may have power supply/inverter board problem due to bad caps, or worst case will be bad lamp assembly, the one shown here has broken lamps, you can hear arcing sound if you listen real close.

I have a n envision 22" flat panel TV purchased


Hello,

I don't think there is still warranty for this TV. Usually, warranty last for 1 to 2 years... In summary there is not warranty for this TV, it must have expired.

To further confirm, check the receipt of purchase. The warranty duration should be stated there.

I hope you understand the above....

Good luck.

Monitor go black after 2 seconds when power is turned on. The green power light stays on. When power is recycled it does the same thing over and over.


Check the caps first.
Please read the guide and see pictures on my links.
If you are going to DIY 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/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

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.
