- I don’t know what happened, it just stopped working and won’t turn on.
- I dropped it, (I dropped it in water) and it won’t turn on.
- My kids… (well, you know how that one ends)
Ok, so it won’t power; doesn’t mean it’s a complete loss. If the camera blew the fuse then you can solder on a new fuse, you can remove the old fuse and bridge the connection leaving the camera without a fuse (not recommended) or you can replace the entire board that the fuse is on.
Fuses are normally just a few dollars, and if you can solder really well, you can probably replace it. Can’t solder? Don’t bother. Replacing the board isn’t hard, but getting the board for a decent price is unless you go used and you never know what you’re getting with a used board or lens, but it’s better than nothing.
Exposure to liquid is a camera killer. I hate to say it, but if this is the issue with your camera, I would have to tell you that the camera is a goner. I want to help you repair it, but corrosion is bad, real bad. Water gets everywhere and causes damage to everything. It clouds up the backlight so your LCD screen has weird shadows on it, it fogs up the lens so you can’t take pictures, it shorts out boards and flashes and is basically the nemesis of all things digital camera. Please do not get your camera wet. Thanks.
Argh! What did my kids do this time? The camera won’t work anymore, what’s wrong with it? Could be our friend the fuse again as above, or could be a “door indicator switch” that tells the camera to turn off when the door is opened. If the switch is damaged the camera will not turn on even when the door is closed.
You can check this by opening your battery door or memory card door and looking for the switch, it’s not hard to see. On Canon Powershot SD series cameras there is one under the battery door beside the memory card slot. See it? Is it broken, jammed up, or totaly broken off? You can try “tricking” the camera into thinking the door is always closed by jamming down the switch, or bridging the connection with a drop of solder. If the camera is under warranty do not do this, try getting them to fix it… though they proabaly will not, and will just fall back on the old “physical damage” thing again. Can’t fix the switch, have to replace the board, only real solution to the problem.
It’s not corrosion, it’s not the door switch, and it still won’t turn on; so what’s wrong? Honestly, it’s difficult to say without $100,000 equipment that I just don’t have. The lens can be defective for whatever reason and causing the camera to short out. There are certain models where a bad LCD will cause the camera to not power. Could be the flash, could be a screw touching the PCB or the frame inside the camera and is causing it to short… Electricity is weird and does weird things.
Right about now you are probably wondering if this book will ever come to an end. No, it won’t, because there are so many different things that can and do go wrong with digital camera repair that there really isn’t a way to list them all. Will my post ever end? Yes, it will thankfully enough.
I do hope that I have been able to shed some light on the mysterious subject of digital camera repair, and if I have helped you to fix your camera I would love to hear about it! I enjoy this business because I know how important a camera is to a person; you want to be able to record the events of your life and they only happen once. Once that time has come and gone you cannot get it back, but with a photograph you can be transported back to that place and time any time you choose. If I can help you with that… to be a small part of so many peoples lives in such an important way is an amazing thing and gives me a “warm fuzzy”.
