Lens cap is off and its asking me to remove the lens cap

If your Megxon C480 camera asks to remove the lens cap but there isn't any, and the display remains black, it likely indicates a malfunction with the lens assembly or a sensor issue. Consider contacting Megxon customer support for troubleshooting or repair options.

The sensor or logic board in the camera must be fooled, or one of them is defect.
When removing and reinserting the battery does not change this, contact a Canon certified repair centre and ask what it will cost to repair this error. Then decide if you want to spend that money for repair or as a start for a new camera.

Really it means what it says.
Switch of the camera, and switching it on again, will reset the program, like a cold boot from a computer. Perhaps the camera could not move the lens barrel and as a precaution it gave this warning. When you removed the lens cap, please check there is no mechanical obstruction on the lens. Then switch on again. When the error keeps coming back you should ask advice to a Nikon certified crevice centre close to you.

The first thing I would try is using one of those rubber pads that are used for removing stubborn lids from jars. If that dose not work, I would use the fact that the Nikon rear lens caps are made out of soft plastic to my advantage. If you have a Dremel rotary tool with a disk cutting tool, you may be able to CAREFULLY and slowly cut away the lens cap. You didn't say which lens this is, but since with most lenses the telephoto position moves the rear element away from the back of the lens, I would set the lens to telephoto before starting to cut. I would start by cutting through the back of the lens cap. Cut a little at a time and try to take off the cap. Proceed slowly periodically trying to remove the cap. Hopefully, the pressure will be relieved and the cap will release before it becomes necessary to cut across the lens flange. When you are done, I would carefully clear the lens of any debris.

It depends what lens cap you have some lens caps you pinch off
Others you pull off some screw off its the easiest thing you can do on the camera you should have had a a1 filter screwed on before the lens cap then all you would have done is unscrew it all.
Then again you may have to take it to Nikon on Wilshire

Remove the rear lens cap and you'll see a row of metal contacts. Simply use a clean pencil eraser rubbed over the contacts.

place the lens cap back and then off the camera. after that turn onn agin and remove safely

KEEP UR HAND CLOSE TO THE LENSES, FACE DETECTION IS ACTIVATED OR U RA MAKING PICTURES OR VIDEOS IN THE NIGHT. TRY WHERE THERE IS LIGHT

Contact JVC, they fix this error FREE. They fixed my GRD-50. It's a common fault with lots of them. Give it a go. Good luck.

I would sugest using an adaptor ring. You can reduce the size of your lens opening down a common size lens cap that will fit your camera. If you can't go this route then give me the make and model number and I will see what I can do for you. LJ
