D-141 Mweapon problems

I have one of Night Vision D-141 riflescope and I leaved it switched on for a long time. When I tried to use it again it didn´t work. It seems to work for just a second every three seconds but the image seems to vanish... What do you think about it? I much appreciate any comment on this regard, Thank you in advance

Re: D-141 Mweapon problems

Sounds like terrmal run away of the power fet.
leaving it on that long caused it to be damaged.
many compact devices have simular toruble.when
you turn it back on it quickly over heats and shuts down. After a few seconds it cools enough to resume operation till it reachs cutoff temp causing the on off cycles.

Works sometimes

It could be a lot of things; such as, faulty wire connection, cold solder joint, HV voltage arcing, corroded battery terminals. intermittent short in the switches. If it stop work, try gently shaking it several times, push the on/off button several times. make sure the battery makes a good connection in the battery compartment. Wrap it up and put it in your freezer for a few hours. There are electronic components that might get hot/warm and by cooling them down they will start working again. I don't know who manufactured Night Owl NOTG1 Goggles or who manufacture the components. Rissia manufactures make a lot of night vision devises and components. Also, there are a lot of countries in world that manufacture NV devises, and their parts. GB...stewbison

Yukon Ranger 5 x 42 night vision goggles just stopped working, I put in new batteries, but when I press the ON button the on light, which is red, just flashes maybe 10 times and then all goes black. ???

Hello, let do this. IR illuminator has a montary switch, that is when you push it comes on, and when you release it the IR goes off and it has a red LED to indicate the IR illuminator is being activated.

When you turn you binocular on there will be a green LED activated. This switch is DTSA---double throw sing activated. That is, one throw of the switch it turns on the binocular, the throw will turn off the binocular.

Also within the control panel there is timing circuit to keep the IR illumniator on for ten second the shuts off. Make sure you have the right switches etc. Let me know, then we can brain storm on this matter. stewbison

Atn day/night vision had scope on for maybe five minutes and left batteries in with the switch in the off position in the morning the batterieswere dead,was told to take batteries out when not in use

Hello, You turn off the scope switch, hey. But did you turn off the IR switch? Never leave batteries in you NV devise. It creates lot of problems. Just take them out and wrap those batteries in plastic bag each and store them in cool dry place. stewbison

My night vision scope will not turn on. My LEDs work but you can not see anything in the lens. Yes the cap is off. I tried new batteries. It has very few hours of operating time. Help!

Hello, Welcome to the world of Russian night vision system. That is right, Night Owl Optics Cyclops NOCC3 is manufactured in Russian. The biggest problem with these monocular and binoculars and even scope is that they use cheap 1st generation Russian image tubes and everything else. It would be cost prohibitive to have it fixed, that is, if Night Owl Optics will fix it for you. Hint: Auction it on Ebay as night vision parts. Sorry, GB...stewbison

I have a NV-100 Compact with illuminator should I have to hold the switch pushed in all the time I am trying to use it?

Not all the time, but if you release the button the image will fade to nothing in a minute or so. This is how it switches itself off. Don't expose it to light while it's powered up as this might damage it.
