Coolpix S50. Sometimes just won't work has a white screen with red exlamation mark and says lens error then a few hours later its fine again. Always seems to happen when I'm out in a club thought maybe it gets damp or something?

Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ...
Here are some troubleshooting steps that you can try that may (or may not) correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try. Some of the later steps do involve some risk to the camera, so carefully weigh your options before deciding to conduct them.

Sometimes the lens is just stuck, sometimes it needs to be replaced. Try to mechanically move the lens in and out by gently twisting, pushing and pulling. If that fails, the gears are too misaligned to repair it without opening it.

If you're out of warranty, there are third party place that replace them such as camera lens repairs.

If you want to do it yourself, there are also free camera repair guide websites that show you how to replace the lens, the replacement part is usually available on ebay.

No. Water ruins cameras, water and damage due to being dropped is even worse. Now that you've let it sit and dry corrosion will have set into various electronic and mechanical components and there will be residual conductive salts left where the water evaporated.

Your camera is unrepairable. Buy another one and take better care of it, or buy a rugged tough camera designed to be "you proof" or given that it fell down a toilet, maybe that should be "poo proof"...

Hello

Thank you for using FixYa for your problem

Always check the batteries first, even try a feash set but if is it still giving the same fault, your camera is faulty.
It should be taken to an authorized repair centre for a repair estimate. Very few digital cameras have any user-serviceable parts.

Please rate our solutions and if you still have problems please call back for more ideas to help you

Try jiggling the lens. Use compressed air to blow out any grit around the lens barrel. If that doesn't do it, you'll need to get the camera serviced.
