I dropped it and now it won't turn on. How do I fix it?

cant turn on

If the cell phone battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

Something more than likely chipped off/broke from the impact of the drop. Have you tried opening the PSP? *Note - opening your PSP will void your warranty.

Things to check first for a camera that won't turn on (no power, no lights, no noise, nothing) are battery contact points, and micro switches that are located on the battery and memory card doors. Troubleshooting tips on other things that need to be checked may be seen here. These tips won't work for every case, but they're worth a try.

But if there is some electrical activity, then you're more likely experiencing a lens error. In that case, see this article.
and this video:

Really!....you've dropped your camera "countless" other times and now you're concerned because this time, it won't turn on!!! You're not sure what else to do?!!! How about not dropping your camera. How about using the wrist strap. Your dropping luck has run out...your camera does not have nine lives.

possibly your ignition dropped a pin, making another key won't help this since the inner workings of the switch itself are damaged or bad

No point-and-shoot consumer camera is worth fixing due to user error or accident. Best bet would be to buy another one or see if you can get Canon to replace the camera. Don't tell them you dropped it and hope for the best.

Sorry! And I hope this helps.

YOU MAY HAVE A BAD DOOR AJAR SWITCH. HOWEVER, YO HAVE A TIMER THAT SHUTS OFF THE INTERIOR LIGHTS AFTER 300 MINUTES. IT'S CALLED A BATTERY SAVER FEATURE. TEST IT OUT.

THE EXTENDED CRANK MAY BE A CHECK VALVE IN THE FUEL PUMP IN THE TANK, ALLOWING PRESSURE TO DROP WHEN YOU TURN THE ENGINE OFF.
OR A BAD FUEL PRESSURE REGULATOR ON THE ENGIEN FUEL RAIL.

TRY THIS TEST, TURN KEY TO "ON" POSITION, WAIT 5 SECONDS, SHUT OFF KEY FOR 30 SECONDS. TURN KEY ON, WAIT 5 SECONDS, THEN START ENGINE. IF IT STARTS RIGHT UP, YOU ARE LOSING FUEL PRESSURE WITH ENGINE OFF.

THIS BUILDS UP PRESSURE IF IT DROPPED DURING SHUT DOWN.
REPORT TEST RESULTS.

PLEAE RATE, THANKS
