You can find spare parts here:

I think this is fairly technical and difficult procedure. Please take extra notes!

And keep extra track of all the screws. I won't specify screw sizes since I do not possess that information!

This teardown is not a repair guide. To repair your Sony Alpha 5100, use our service manual.

  1. Turn your camera off
    • Turn your camera off

    • Remove battery

    • Remove memory card

    • Detach camera belt if you have it attached to the camera

    • You might want to disconnect camera lens as well. Just remember to keep your image sensor away from the dust and your own fingers!

  2. Removing single mounting screw of the flash plate cover
    • Removing single mounting screw of the flash plate cover

    • Using opening tool or guitar pick pop the plate off. There is a little hook so do not force it! Yellow square shows opening where the flash plate cover hook goes.

    • Gently slide the plate off the camera body. You might have to move display out of the way couple times.

    • First picture illustrates what we are trying to remove

    • Pop the flash. And remove first screw

    • Remove 2 more screws on the side of the body

    • Pop the memory card door open

    • Remove 2 more screws

    • Remove 3 more screws from the bottom of the camera

    • Use opening tool, guitar pick (or whatever else) to pop the front plate apart from the main body.

    • Be very gentle!

    • Remove the front plate

    • Gently separate NFC flex circuit from the body. It might be glued to the body so take extreme care not to damage it!

    • Continue separating circuit down the line. Should be pretty obvious procedure...

    • Remove movie button from the body of the camera as well. Move flex circuit out of the way.

    • Pop little metal stopper of the button panel away from plastic body of the camera. (Look at pictures 1 and 2 to find a difference)

    • Slide the whole button assembly up until you can separate it from the body.

    • Gently pry green flex circuit assembly from the middle body. See picture #2.

    • Now you can remove button panel flex circuit from middle body flex circuit. (Read: blue flex from green flex). And separate button panel completely from the camera!

    • Remove 2 screws holding LCD screen assembly

    • Pry LCD screen assembly away from the camera body. Use opener tool, guitar picks, whatever. Be gentle!

    • Carefully move LCD screen away from the body. It will be still connected to the PCB via flex circuit!

    • Pop little latch of the LCD screen connector and gently disconnect LCD screen from the camera body.

    • Pop flash once again. You won't have actual button but you still have metal lever to do so.

    • Unscrew 3 screws that attach flash to the camera body.

    • Gently move away flash from the body. Disconnect flash flex circuit from the camera body. No latches this time!

    • Carefully slide flash tray out of the camera. See last picture illustrating tray mid way out of the camera. Pull the tray completely away from the body.

    • Remove 2 screws

    • Remove 1 screw. I am not 100% sure but I think it is black one. The rest of them are silver.

    • Remove yet another screw

    • And the last screw, tucked away behind the frame. Might require pretty skinny screw driver...

    • Gently pry the mid frame from the body. Make sure all the flex circuits are out of the way. This step might be tricky. The frame might be glued so take extreme care not to damage anything!

    • You probably do not have to remove camera mount. But I did so anyway!

    • You probably won't have to remove camera belt clip either. I would recommend using it as extra leverage while removing mid frame from the body.

    • Unscrew single heat sink screw

    • Detach sticker from the memory card connector

    • Remove heat sink. It might be glued with thermal paste to the mother board

    • Open latches using guitar pick or opening tool.

    • Disconnect image sensor flex circuits from the mother board.

    • Gently pry flex circuit from the connector! Be careful to apply just enough force!

    • You may pull the speaker out of the enclosure using tweezers while you are working around this area.

    • Disconnect WiFi antenna cable. Very gently pry it off!

    • Disconnect 2 camera lens flex circuits in the right bottom corner of the mother board. No latches here!

    • Lift masking tape away from the mother board. Most likely your masking tape is going to be black not red!

    • Disconnect 2 more flex cables. One of those is power flex circuit and the other one is either flash or buttons flex circuit.

    • Disconnect shutter flex cable from the bottom side of the mother board. No latch here. Gently pry it off! I bet you are master at disconnecting those off by now!

    • Make sure that both microphones and speaker is out of the camera body at this point.

    • Disconnect one more flex circuit connected to the bottom of the mother board. No latch here. It is either flash or buttons flex circuit.

    • Remove mother board

    • Gently remove plastic body assembly. Pay close attention to the flex circuits around the body. Make a note which ones supposed to stay with the body frame and which ones stay with the front assembly.

    • Plastic body frame is shown in the last picture. It is shown without battery door. You don't have to remove battery door!

    • Open latches first. Gently remove both flex circuits attached to the image sensor. Take a note which one goes where

    • Remove 5 screws

    • Remove Front Metal Frame

    • Remove Image Sensor Assembly

    • You can continue disassembly if you want to separate image sensor from the shutter. I have not gone that far but I am sure it should not be too difficult to figure out.

    • Last picture shows front case of the camera. It does not include flex circuit. You should have flex circuit still attached to the front case!

    • Note how camera belt clip is still attached to the front case of the camera. You don't have to detach it!

    • Reverse previous steps to assemble the camera! Pray you did not forget anything otherwise you camera won't be working properly!

    • I ripped one of the flex circuits while disassembling my camera. I got it replaced. I did not have this guide so I hope you won't make same mistake that I did!

    • Have fun! And good luck if you need it!

Hi, Kirill

I have teardown the 5100 . I’m trying to light the camera so that could beinstall in UAV.

It could be work at very beginning of teardown. I removed the useless part, such as the LCD, flash light, and heavy frames. After that I get a test. It could work still.

But with a weekend pass by. It cant work any more.

It look like short circuit.

when I try to open the camera with a full charged bettery. it won’t work. this process cost 3 seconds.

and then I measured the voltage of the battery. It’s voltage is 0. charge the bettery with 5 seconds. back to full charged(through measured voltage).

I have no idea with this situation. What should I do?

Would you please help me?

You can email me if convenience. email:

Thank you very much!

Hi Jason,

Yeah, I am not sure what the problem is to be honest. I don’t think this camera have been designed to work half disassembled .

I would look for more appropriate camera. Sounds like you might have short circuit somewhere. You might have to replace one of the internal boards. I am not sure, you would have to debug to see which one failed.

Anyway, best of luck

Hi Kirill! So I have a problem with my Sony a5100. Whenever I half press my shutter button or zoom using the lever below the shutter button,my cam will turn off all by itself and I need to press the shutter button for like 5 seconds for the screen to turn on. Do you have any idea what’s wrong with my cam? Please help.

Thank you, thanks to this instruction I replaced the PCB board in my camera.

I followed a youtube tutorial looking for a way to fix the overheating issue in my a5100... I did it correctly, at least the disassembly part. The big misconception comes up at the LCD screen ribbon cable part of this tutorial. The guy in the video claims that the conector where's the ribbon cable fits, is friction fit... IT'S NOT. I've learned it by the hard way. As it’s shown here, that is a flip up conector.

Keeping it short, i ruined the LCD screen ribbon cable and maybe the LCD screen connector in the board too, the contacts in both to be specific. Or that was my initial thought.

Where I live is almost impossible to find, at least, a decent technician but I found a good one outside the city. It cost me a bit expensive but he made it, with a drawback, the LCD screen shows signal but there’s a bizarre green/yellow color form where it's supposed another color has to be in.

At this point i was working with what i have, but i really wish that there’s a way to recover the full correct function of the LCD screen.
