The fluorescent back lamp and / or electronic ballast is failing. These parts are fairly inexpensive from suppliers on the internet, but require some finesse to remove and replace the part(s). You may also need to do some soldering to make the repair as well.

If you can't do these repairs yourself, don't be surprised to learn that the cost of having someone perform them for you is not worth it. Some places charge a diagnostic fee (which may or may not be applied to the repair cost) before they'll even open the monitor. Check out new monitor pricing before agreeing to the fee or at the very least - authorizing a repair.

I hope this helps - good luck!

Monitor issue


Just sounds like the monitor cable is loose or bad or the input mode on the monitor is set wrong - set it to auto or step through the modes.

My Envision 9410 Monitor flashes on and off. You see the picture fine, but then it goes to a black screen and then back to seeing desktop. The power light goes on and off while this is happening. Is...


Its either going to be the inverter or the lcd going back and it can't keep the screen lit.

Also I've seen it where the capacitors on the power board go puffy and they need to be replaced.

It will be one of those three things.

Monitor started to flicker then went blank


I have a envision professional series and I love it, but I will get to the point.
I recent ly received a Envision EN9410e monitor, had the same problem (flickering screen then turned on, then off then on then blank). The problem is bad capacitors. There are 7 electrolytic capXon capacitors that will need to be replaced. You should see if the caps are bulging or leaking, if so replace. As known by many replace with the same capacitance and voltage. There are a few incidences that the capacitors where replaced and the problem wasn’t solved; this is because the cap problem wasn’t taken care of and damage occurred to another part of the monitor. The back light is a Royer oscillator (cool things) and it uses two smd mosfet transistors. They are on the green side of the circuit board near a big control chip (they each look like a off rectangle black square with eight pins) you need to see if there is any carbon or chard residue between the pins or burning smell from them, if there is you need to remove the transistor and do some board repair then ether put a new transistor or try the old one. No offence to the people at Envision but not smart putting the drain, gate and source so close to each other under the chip where there is such high voltage! Hope this helps.

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.
