How do i turn on or work my polaroid rainbow one step vintage camera?

Burns?? could it be that what your seeing is a "corona" (brown ,with white and orange ) if so I bet your film compartment is letting in light , this happens on vintage equipment because they used velour type material as seal on film door and other places and it drys out over time and allows light in

also is your shutter working properly ??(clik don't mean working) a mt camera with film door open shown toward light source shouldn't allow light thru , wouldn't be the first vintage shutter that ive ever heard of sticking

There are several instructive videos on Youtube. Just run a search for "Polaroid 100 Land". Seeing it works better than reading :-)
I hope this helps.

Remove the film, blow out the chamber with a good airbrush (where the film/battery goes). Clean and replace the film (give it a wipe). Sometimes the contacts get dust on them and stuffs everything up

These were added at the time of development. The digital technology did not exist to build the capacity into the camera.

HI there please send me the model no of your camera.

Polaroids are known for bad capacitors in their units
pull the back off look at the circuit board check for bulging or leaking capacitors.

there is no battery in the camera. the battery comes from the film. the film has a battery in it already. you MUST have film in the camera for the light to go on and the flash to go off. all polaroid camera's are the same. you must have the film in the camera for it to work.

the flash will work when you put film in. the film has a battery and the camera works off the battery in the film. the arrows make the picture dark or light.
the polaroid spectra onyx made in 1987 is a totally sharp and beautiful looking camera. you also can put filters on the front of it. this camera was used by law enforcement many years ago so it is made very steardy and well. i own one myself and the pictures are perfect everytime. look this camera up on Ebay, you will not be disappointed.

also, here is a website for you to look up film information
polaroids.theskeltons.org

this website will have everything you need and more

Here is the web site where you can print yourself the user manual for this camera. http://www.polaroid.com/service/userguides/photographic/propack_ug.pdf

This appears to be a component fault. Contact Seller[if still under warranty] or Polaroid for a replacement
