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.

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!

Monitor is dim


sounds like the flourescent back light is going out. If you are brave enough, open the monitor and look at the lamp tubes on the sides of the LCD panel and look for the ends being blackened.. if it is, replace the bulbs and the thin driver board for the lamp as well.

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.

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.

Hi, i bought a used envision G22LWk... Can you tell me why it turns on? Then, in about 2 to 5 seconds it goes blank? I didnt get the guide with my monitor or i would look it up.


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