The illuminator is not working, what do you think might be the problem. Thank You Ken


Hello, what illuminator are you referring to here. The image intensifier tube, or the IR illuminator?


I am suspecting it the those Russian manufacture image intensifier tubes I am also accusing them....Russian NV manufactured of installing electronic destruction timer in the their image tube.



I fairly sure that you Famous Trails FT1200 NV Monocular is about five years old. Five years is the average on the image intensifier tube life span.



I have a few extra Green Russian Image tubes there not new but the will work but for how long---who knows...



I would call Famous Trails NV Optic company and see what they will to charge to fix you FT1200 monocular. There good possibility they will tell you that they can't repair you FT1200. But they will take it for a trading on a new model (made in Russia) for a few---hundred dollars more.



If you fill like not do this then auction it on eBay. I need some parts or if you want it fix then send it to me. drawbridge21@q.com That my email. What ever you do I wish you lots of luck in your endeavors. GB...stewbison

Cannot see thru optics. ifr comes on but still cannot see any image? can the back of the night vision come off to check the power illum light?


Hello, so the image intensifier tube light up. Shake it and listen for parts raddle around inside.
How long have you own this Night Owl? Have you been using night vision on bright lights?
If you have the intensifier tube is gone back to the Red Star....it died! The IR operates on a different switch than the controler, ccfl inverter, multiplier, image tube. Sorry. stewbison

There is good bet that I have a tube for this, but it not worth sending to me. Also, maybe it not the image intensifier tube but something else in the electronic.............Made in Russia--Red Star

I have a ITT nightquest that is around 12 or 15 years old and stopped working, i replaced the batteries and when i press the power button all i get is a random red flash of light,,, any ideas of what is...


Jello, It a very nice night scope then and even to day, it American made. Those ITT 1st generation image intensifier tube have a life of about 10K hours+. If it had a few exposures to bright lights this will take a way from the life of the tube.

The only way to trouble shoot the problem is to take it parts. ITT will not provide any information on this Nightqest NV devise. You'll need someone the knows electronic in depth, troubleshoot solid state devise, and make HV ingitors for the tube in thousands of voltage. The problem could a simple passive component to the image intensifier tube has quit. Expensive to repair if the tube is bad. stewbison

There is not picture its just vioce


Battery OK, IR light up, no green image on the intensifier image tube, correct! What type of voices are you hearing? Give ATN Aries 390 two Zolof and wait two day, just kidding!!! The noise is a crackling, high freqencey hum, popping, etc. Also remove the eye lens, it screw off, then remove the scope to someplace where it semi dark. Turn it on and observe the 18mm white plate and see if it turn green---no green---no look see---no image intensifier tube, it dead that is the mage tube. stewbison.

Cannot see though it,just stop working


Hello, about 85% of the problems with these Russian NV monculars are the image intensifier tubes. They can't take any kind of abuse. Just droping it will sometimes destroy the image tube.
and it to cost prohibitive to have it fix. Sell it on eBay for parts. Sorry. GB...stewbison

Hello, your Night Owl NOCC3 monocular needs a new image intensifier tube. It is cost prohibitive to have it fixed. Auction it on eBay as "night Vision Night Owl Parts only" GB...stewbison

Little black and white dots inside the lens


It's not a problem with your NV monocular. These spots will occur on any image intensifier tube. EXAMPLE: Military standard states that if more than one black spot appears on the tube, then this image tube is rejected for use by the US Military Now like you NewCon Optik DN 140M it manufactured in Russia and they quality control doesn't even match the US Military Standards. On scale 1 to 10; US Military rating for the image tube would be 10+ while the Russian maybe 2+ and I said maybe. Another thing to remember here is that no two image intensifier tubes are the same. It just like finger prints on people not two are the same. It normally. stewbison

Lights come on but you cannot see through it


Hello, it seems another Russian manufactured night vision monocular has died. Sorry to say, but the image intensifier tube is bad. I really doubt that Night Owl Optics in El Paso, Texas will fix it for you. Because of it age of 5+ years old. Hint: auction it on eBay as night vision monocular parts. Sorry. I would fix it for you but the last one I fixed, it took me two months to find image intensifier tube and it was used. I wish you all the luck. GB...stewbison

Degassed tube how to fix? repair?


Do you mean de-purged tube or de-gause tube? Image intensifiers are not like CRT where they have a gausing problem. If a spot is burnt into the image intensifier, it unfortuantely is permanent.

If you mean de-purged (gasless), this can be done by a reputable service/repair workshop with nitrogen.
