Yukon Ranger 5 x 42
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

Green light comes on but no picture. where is best
Hello, most of these night vision devises are repaired by the companies that
offer to sell and service. It almost impossible to find someone other than the
dealer to repair them. You try Morrision Optic they have big web page on the
Internet. A little warning here. These companies they sell NV devises are not
necessarily the manufacture of these NV devise. Russian make a lot of these NV
devises for US NV companies.
I repair them also but it hard for me to get parts, and I can make other
parts if I can find some dealer that will sell me parts For a 1st generation
cheap Russian image intensifier tube will cost about $175 each and sometime I
can get them cheaper. GB....stewbison

The Main IR Light. (the one used for long
Here we go. Take it to electronic repair facilities. See if the can replace the LED IR. Now if they want. Call Yukon NV Optics and see what the charge, normally these companies have flate fee they will charge. They really don't make it easy for the owner to repair these NV binocular. Basically, the binocular will almost be totally taken a part. stewbison

Yukon 2.5 x50 nvrs tactical
Hello, don't worry about it. It is HV to the image intensifier tube. The battery
voltage goes through control circuit then to ccfl inverter (here is were dc
voltage is switch on and off and switch dc voltage is step up by toroid coil
that has two input and only two out puts). By impulsing the coil with two
different switch dc voltage on the input this make the current lag the two
different phase voltage by 90 degrees. Here is where the strange noise is coming
from. The toroid coil is encased in iron case and if half of this iron case is
loose, it makes case vibrate so the noise.
Now, the voltage come out of the toroid coil is switching dc (one could call
it AC because that what AC voltage is, it switch between positive to negative)
this voltage is about 300 to 900 switching DC voltage. This voltage will be
applied to a 1/2 wave voltage multiplier (this voltage multiplier with have
anywhere four four stages to 10 stages depend on what the input voltage to
Low the voltage out of the ccfl inverter the more stages the multiplier will
Now, the voltage multiplier will double the voltage per stage to need image
intensifier tube voltage of 12000 to 45000 volts---DC switching or AC what ever
one wants to call it. This voltage will bit you but it doesn't have a lot
current associated with it, the current would be in the 10 to 15 ua (micro-amps)
Now, you know. GB...stewbison

Trying to figure out how old my Whirlpool washer is?
Trying to figure out how old my Whirlpool washer is Locate your machine's nameplate, which contains both the model and serial numbers. On top-loading Whirlpool washing machines, open the lid and look for the tag at the top rear of the tub. On front-loading washers, the tag is usually inside the door or near the bottom of the left or right side of the cabinet. If the tag is not in one of those places, pull the machine away from the wall and check the rear. Record the serial number with a pencil and paper or take a photograph. Be sure to record the serial number, not the model number. Decode the serial number at an online source like Appliance Cafe or Appliance 411 (links in Resources). Whirlpool serial numbers include a code in the second character for the year the product was built. Before 1990, the character was a number; from 1990 to 2010 the character was a letter. The number sequence started over in 2011.

I bought 2 outdoor CCTV.camera RV537B with night
I think I answer you question--when?? Take the good CCTV camera and hook it up to
monitor. Then hook up the CCTV camera and turn it on. Point the working CCTV
camera at the bad camera that is turn on. Now, look at the monitor which is
working with your operational camera. Look at the bad camera while it on, and
see how many IR LED's you can see on the bad CCTV, while it turn on. You should
be able to the IR LED glowing red. If not, then there is a problem with bad CCTV
IR LED's. Short wire, no power to the IR LED's. stewbison
