Nikon Coolpix P520 lens replacement or repair 

If it was never connected to anything electronic, it's probably shielding. A crack or tear in shielding doesn't generally cause any trouble. Almost all portable electronics have copper shielding tape some place or another, and lots of repairmen destroy it without significant consequence to daily use.

I would suspect the zoom switch, it might be stuck, or may have corroded from moisture. A stuck zoom switch can sometimes be the cause of a lens error message.

Hey, my camera has the same issue, did you repair it at last?

mvsgeek The only thing that comes to mind is a broken battery door sensor. If that's broken, it will think the battery door is open, and refuse to turn on. That's the only thing I've seen cause a no-power symptom on these. If that's not the culprit, and the power button seems to be functioning correctly, it's probably either the socket where the battery connects, or a fault in the main board.

I can't find anything that looks like a battery door sensor.... :-(

mvsgeek I don't have one of those available to me to look at right now, but they're recall a small button that is pressed in when the battery door is closed. It's possible that yours doesn't have one, but unlikely.

Same issue here on my P520. Won't turn on, presumably after a few bangs in the suitcase. So basically could be anything... I've checked and reseated the cables but didn't help.

@@ArtByStrongWolf I just tried powering on my P520 with the battery door open and surprisingly it worked fine. Shame, I have a second P520 which doesn't turn on and I was hoping for a simple fix. Excellent overview of disassembly, thanks.

Dora Richey I haven't replaced an LCD in this model, but I would expect that you will. Most models require that.

If you're batteries are old, they may not actually be taking a charge, regardless of what the charger indicates. If a new main battery doesn't fix it, it could be your internal clock battery. If this model has an internal clock battery, I would try replacing that, next. If it uses a capacitor, you're probably facing a logic board failure.

​@@ArtByStrongWolf Hi, thanks for the reply. I checked the internal battery, I think it is ok: 2.99 volts. Do you think that uncoupling it for a few minutes, for a main board reset, can fix thw problem? I left this machine for a long time when I put it in the drawer it was ok, but now it doesn't turn on anymore.

@@mauri740 2.99 volts is slightly on the low side, rated voltage is usually the minimum operating voltage, and I'm guessing that's a 3v battery. Most devices have more tolerance than that, but there's no guarantee this does. Disconnecting the battery, then draining the flea power by holding the power button down for 30 seconds, then reconnecting the battery would be a good idea.

Is this a new problem, or has it done this since you bought the camera? If the problem is new, I would suspect the shutter switch is faulty, and can be replaced if you can find someone with the part for sale. If the problem has happened since you purchased the camera, you might not be letting it focus before pressing the shutter; if that's the case, try holding he shutter halfway for 15 seconds before you take the picture.

This has been getting worse over the last year or so. It's a problem with the button. Where would I find the part?

@@mover8012 Here's the part on eBay. It's coming from China, and I'm not familiar with the seller, but it looks like it should fit your camera. rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F332705935554

Unfortunately, this was brought into my shop by a customer, and I no longer have access to make further videos.

Do you remove the battery of the camera after use ?

Have you tried soft lights and romantic music?

Unfortunately, you don't have a DSLR, so you would have to disassemble the camera in a similar procedure to the P520 shown in this video. It is definitely not a simple fix, and will require some time and attention to detail.

The method will be similar, but not identical. I don't have one of that model to create a tutorial video from.

You can by following the steps in this video. You will need to find a replacement lens assembly, I would suggest looking on eBay.

It is most likely a broken switch. It can be easily replaced once you take the lens out, following this video. Good luck!

zibodiz thanks for the answer! But after i bought it i reset the configuration and the button started to work fine! So i made a very very good buy ahahaj

Loki High There are a few things that can cause that. The first thing I'd check is just to verify that the display isn't turned off. Switch it to playback mode, and see if anything shows up. Next, try taking a picture; if it takes pictures and seems to function correctly aside from the screen, you probably have a broken LCD. Those can be easily replaced.

No. I can't take a pic. How do I switch it to playback mode?

Playback mode it engaged by pressing the button marked with the blue 'play' triangle inside a box, on the back of the camera. It's just above and to the right of the 4-way control. Just to the left of the lighting bolt symbol. When you try to take a picture, does anything happen? Can you hear the shutter? When you turn it on, does the lens move?

When I turn it on the lens move, yes. But I can't zoom in or out. I've pressed that 'play' button and it's done nothing

It sounds to me like the mainboard has an issue. The top controls (zoom, shutter, etc) are connected to the mainboard through a different ribbon than the rear controls, so we know that it's not a cable issue. There's definitely more than just a bad LCD, because if that were the case, the zoom slider would work. I definitely think it's an issue with the mainboard. Unfortunately, I don't know where you'll find one of those for these cameras. You're probably best off finding a camera with a broken lens, and moving your lens into it. The lens is the part that is broken the most frequently, so it's definitely worth moving into another camera.

There are slight differences, but the teardown should be similar.

I figured it out. It is shown and explained pretty poorly in the demonstration, but what piece you need to lift is the GPS plate above the Flash. In order to life it, you will need to raise the flash, and then use a thin flathead screwdriver (or any tool small enough) to gently lift up where the slit is shown under the GPS plate. What is explained well, is that when you insert the tool under the GPS plate, twisting it is all you need. As you only need to raise the GPS plate just a little bit, and then you can feel the two halves of the camera seperate, to where you can move on to the inner workings of the camera. This explanation is ridiculously late, however I at least hope it clears up how that unclear step is taken.
