    Night vision was working properly when stored for just few days and when taked out of case, simply doesn't work. No hits, no humidity, new batteries, and view is black.

    Everything looks good, and indicator lights turn on.

    I bought new Night Vision Monocular NVMT . It never worked. It looks darker inside than outside. I changed two batteries( new) to exclude battery failure.To make things worse I lost original bill of sale. I have proof of purchase on credit card statement.The producer is Yukon Advanced optics.I wonder if there is shop in Arizona that can repair it. I can use some advice .

    Same identical problem. Stored, put new batteries in, lights go on and black lens. Used only a few times and is still brand new. Any clues? Your input would be greatly appreciated and thanks in advance. Bob

    Brand new unit worked for a day then was put away without the battery in it. It was stored in a dry temperature controlled home for 6 months. When put back into use the unit did not work. I replaced the battery but still no luck. I can't believe that other people are having the exact same problem. It sounds like a manufacturing defect of some sort.

    Same but different My NOCX3 did this. brand new, I played with it for 10 minutes tops. Took the battery out, stored indoors. 3 months later I put battery in and turn on. BRIGHT green light in center dimmer light as it should be around edges but not fseeing anything through the it.

    Returned it for a NOCX5 and same exact scenario. tinkered with it for a few minutes, pulled tha battery and put away for years. put in battery. BAM, same issue. AND no response at all from www.nightowloptics.com

    These aren't that cheap, what's teh deal?

I have seen a few of this model and the tubes were gone in each case. Best way is to check if HV present at tube - get someone who knows what they are doing to take a look. If it is the tube, it will be expensive to repair. Unscrewing the lens may reveal that the inner surface of the tube has dark marks, also indicating possible tube damage.

Yes, If you turned the Night Owl on during the daylight hours, or looking directly into bright lights.
If you have done this more than few time it could have damaged the image intensifier tube. If this happen to many times, it's finny, kaput, so long, it gone south, and gone bye-bye.

Looking at bright lights is damaging to NV devise. The intensity plate in the image tube, magify the existing light about 3000 to 8000 (radian light from the stars, moon and other light sources).
You have 80mm front lens on the Night Owl NOCP5. This mean that more light can inter into image tube.

Sir, have you been looking at bright lights, operate NV system during the day, have you? If not, there could be something else worng with you Night Owl. stewbison

Hello, is the IR glowing red, don't look into the IR lens. Just place your hand in front of it and see the is a red glare on your had. If there is a red glare then IR is work.
Another thing when you taking a look see through the Night owl NV monocular there should be a green glow from the image intensifier tube, if not, then the NV monucular isn't working properly. stewbison

Hello Here Night Owl Optics owner manual web site for your monocular: http://www.nightowloptics.com/documents/NexGenMonoMULTImanual.pdf

One more thing. DO NOT LOOK THROUGH NV MONOCULAR DURING THE DAY, OR LOOK AT BRIGHT LIGHTS. This will destroy the image intensifier tube. Bright lights will make it go south faster than Speedy Roadrunner. I need parts if the image tube is gone. Night Owl Optics in El Paso, TX will charge you about $200 plus parts and shipping to repair it. So, listen no looky at bright lights in the neighbor bedroom window, hey. GB...stewbison
