Hello, when you turn on you Bushnell NV devise does the green come on , looking through eye piece. If it a white oval screen, then check the batteries and make sure the polarity is correct.
If you don't have the green screen in the image tube. Then it not working normally and they is a good possibly that the image intensifier tube is bad. Contact Bushnell ask them what it cost to repair it. stewbison

One image is slightly above the other at all distances. After using the binoculars for even a couple of moments, my eyes are strained. The problem was present when the binoculars were purchased, however...


The oculars are not aligned properly causing double vision. Check on the binoculars to see if there is a place to adjust the alignment of either of the oculars. Look for any loose screws that may cause the two oculars to be out of alignment.
If this is not the case try adding some torque to the binoculars to see if the will adjust to where they will both point in the same direction. The eyes can fuse disparate images slightly but there is a very small range that they can handle. If the two images are separated by more than this small amount it will cause eye strain and double vision.

I have a pair of Plastimo military binoculars which have been fine up to now, but suddenly, despite being able to focus using the two eye piece controls, I cannot get anything other than a double image, no...


Hello - I never had Plastimo before but I have had a similar problem with double vision on a very similar looking pair of binoculars.
The eye piece movement just re-aligns eye focus differences , a double image usually means one of the lenses has moved inside the main tube. (usually from a knock/fall etc)
Can you rotate either one of the tubes ? On my pair I had to rotate anti-clockwide and found a prism inside that had slipped after a fall -
Close one eye and try to gauge which side is the best side -- Ray

You have the eye piece which must be trimmed and set to your vision and it is only logical that you are able to focus on the object in question to adjust the focal for a clear sharp image.

Can not focus, all images blurry, no clear images


Normally this problem is caused by incorrect setting of the dioptre. This is a "focus" ring on the eyepeice which adjusts for the strength and position of the eye. Try adjusting this for best focus at about 5-10metres prior to focusing the unit.

loosen the the thingy behind the lens adjustment, you can turn it clockwise or anti-clockwise which it will go down or up, thats it..problem solve for your 5ft focus problem..in the double vision, you gotta line up the eyepiece center to your both eyes..problem solve again

Double vision on my Mitsubishi 46 inch width screen--TV is 5 years old


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.
