Help The camera was working fine 5 days ago. Yesterday when I tried to switch it on, I assumed that the battery was flat so I charged it but when fully charged the camera still won't switch on. Please help!

The new battery was charged before you put it in? Or you just assumed it was charged?
When was the last time everything ran fine? yesterday, or half a year ago? because in a long period, lots of things could have corroded or just got defect.

Very odd that both cameras would stop working at the same time, has someone else abused them?

Removeing the batterys for a while is a good enought reset, check the battery connectors and contact your dealer if they both have warranty you will get them repaired or replaced for free. other than that I can recommend you a repair man if you provide me the city you live in.

Will they go off if you unplug the headlight switch ?

Well you mentioned that it worked fine yesterday with the battery out of the box. That should tell you that the camera and the battery are both fine. The issue is likely the charger itself. Try recharging it again, and double check that you inserted the batteries correctly, and that any switches (such as for 2 or 4 battery charge) are set in the correct position on the charger. If this doesn't work, take the charger back to the store for exchange/refund as defective.

Your problem may be due to weak/worn out batteries or corrosion on the battery contacts inside the camera which can prevent the full power of the batteries from flowing into the camera. Try this free fix before you do anything else: remove the batteries and wipe the camera contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sandpaper). Remove any residue that may have fallen into the battery compartment during cleaning, then wipe both ends of the batteries and place them back in the camera and give them a full charge (assuming that you are using rechargeable batteries). This cleaning clears the problem about 90% of the time. If it doesn't work for you, it may be time for new batteries, or the camera may have a problem that requires professional repair.

Wow, this is trully amazing. I went to do a search on why my camera wouldnt turn on the past couple of days, even after i charged all THREE of my batteries and found similar complaints within the same time frame!! WOW. We need to get together and fight this, cause its suspect!!! I bought mine in Mass, anyone else?

1.See what the camera manual suggests.
2. Charge the batteries fully before using them. New ones are often not charged up. They could have been in a warehouse for months.
3. The electrical contacts on your camera, the ones that interface with the batteries, may be a little corroded. If you can access them easily, try cleaning them with the eraser on the end of a pencil. Same with the batteries themselves.
4. If exposed to prolonged high humidity, electrical problems may include not only the power supply, but other electrical switches, such as the reset button., which you cannot address on your own.
5. call the manufacturer

camara has been working fine till yesterday, poewer won't turn on, to take pictures, but it turns on when i moved the tab to brouse pictures, bur when I switched it back power won't work

If this happens allot of the times you have to remove the battery from the camera for 24 hr so the camera's compositors can discharge all the way and not it is not the circuit board. Some time the circuit over loads and has to be discharged because of the polarity the electricity is travailing thought the circuits now I know diodes are suppose to prevent this but it is a common problem. hope this helps.
