My old Canon PowerShot S500 digital camera stopped working suddenly one day.

The camera would beep loudly and display an "E18" error code on the LCD when you tried to power it on. This code means the lens is stuck and won't extend/retract - this is a common problem with many Canon PowerShot cameras. I assumed some dirt or grit got inside and jammed up the lens.

Attempts to unjam the lens via external methods failed, so with nothing to lose I decided to take the camera apart and attempt to fix it.

The following photos show how to dismantle the S500.

(FYI the PowerShot S500 is a 5 megapixel camera introduced in Feb 2004)

This teardown is not a repair guide. To repair your Canon PowerShot S500, use our service manual.

    • There's a small loose black plastic piece in the space beside the flash. At first it dropped out and I didn't notice where it came from!

    • Remove the plastic piece, noting where to re-install it later

    • Here is the back of the camera without the shell. You can see the switch contacts on the flex circuit along the bottom. They're attached to the small metal plate that we'll remove in the next step...

    Sony branded LCD in Canon camera ?

    Quote from nieris:

    Sony branded LCD in Canon camera ?

    this is not as unusual as you might think. Sony makes LCD displays that are in many different kinds of electronic products - they have a component business and a separate consumer products division, as do many other companies that you might only think of first as a consumer brand. For that matter, Sony also makes CCD sensors used in other manufacturers cameras.

    I went one step further, removing the CCD array from the back of the Lens Subassembly. Where can I get a functional CCD array for replacement?

    Great pix and description. My camera would not display an image, nor take a decent picture. I suspected one of the flex circuit connectors was no longer making good contact, but would have been in the dark without this description. I followed the instructions, took my camera apart, put it back together, and viola! It works! Thanks a million!

    It's not surprising to see other branded products as ODM/OEM (Original Design Manufacturer/Original Equipment Manufacturer) products within things.

    Many companies produce parts for other things - if you look at another picture there is an NEC chip in there as well.

    I've got a Vauxhall Zafira that has some parts in that designed by Porsche which you wouldn't think.

    Also the owner of Sanyo was Mr Matsushita's (Panasonic) relation and some Sanyo parts found their way into Panasonic products (and now Panasonic own Sanyo).

    Sony also have worked a lot with Philips for things. The CD laser was a Sony/Philips invention and the TOS link on most devices is also called the S/PDIF socket standing for - Sony/Philips Digital InterFace

    So rivals do quite often work with each other in an ODM/OEM setting.

    • Remove the screw on the bottom plate. While we're at it, there are 2 screws on the side near here (2 circles at left). They hold the tripod socket to the side frame.

    • With the 3 screws removed, you can now gently lift off the bottom metal plate.

    Добавить комментарий

    • Here's the bottom plate removed. There's still a flat ribbon cable connecting it to the camera...

    • You can see a small black microswitch on the right end of the metal plate. The switch detects whether the battery door is closed or open.

    Добавить комментарий

    • ... gently flip up the black catch at the edge of the ribbon cable connector. You can now pull the ribbbon cable out of the connector.

    • In the 2nd photo, you can see the bottom plate, along with rear button switches, and battery door microswitch.

    • Note: there is still a clear plastic insulating sheet attached between this assembly and the camera. It will be detached at a later step.

    • Remove the screw holding the flex circuit under the mode switch (red cicle).

    • The yellow square points out a small ribbon cable going to the LCD screen. This ribbon cable powers the backlight for the LCD display. Gently pull out the ribbon cable from the connector.

    Добавить комментарий

    • On the front of the camera is a 2nd ribbon cable going under the camera to the LCD screen - this one contains the data and timing signals which drive the display.

    • Carefully lift the black plastic latch and then pull the ribbon cable out of its connector

    • The large black integrated circuit on the left is an NEC microprocessor, apparently a custom variant of an 80186. Above the tripod socket is a small battery - for maintaining the real-time clock.

    • Remove the 2 screws holding the LCD display module (already removed from the rest of the camera in this photo)

    • It's not visible in this particular photo, but the LCD display module is made by Sony - part number "AM313EKA"

    • The LCD is a 1.8" active matrix TFT LCD

    Добавить комментарий

    • There are 3 more ribbon cable connectors on the front of the camera. Gently flip up the black latches at each connector...

    • ... and then the ribbon cables can be detached.

    • Remove the 4 screws holding the main logic board to the rest of the camera.

    Добавить комментарий

    • Before you can remove the logic board, there's another ribbon cable to detach...

    • ... gently flip up the blue catch on the socket then slip the ribbon cable out of the socket.

    Добавить комментарий

    • Gently lift the bottom edge of the PCB, and you'll see one more narrow white ribbon cable attached to the bottom side.

    • Gently pull the ribbon cable out of the socket (there's no latch on this connector)

    Добавить комментарий

    • Here's the PCB flipped up and away from the camera chassis.

    • Note: there are 2 flex circuit paths connecting the circuit board to the chassis - they are soldered and can't be detached without re-soldering. Be careful not to bend the flex circuit too severely or it may break. I had to resolder one of the connections after I was done.

    Добавить комментарий

    • Here's the back of the main logic board. Note the DIGIC chip (main camera processor chip)

    Добавить комментарий

    • With the main logic board swung aside, the target of our repair is nearly visible! - the lens module...

    • The 2nd photo shows another view with the logic board out of the way. The clear plastic insulating sheet holding the lower metal plate is fastened under here and can now be removed

    Добавить комментарий

    • Under the ribbon cables there's another small circuit board. This one is connected to the lens module and appears to contain various motor control chips.

    Добавить комментарий

    • Remove the 3 screws holding the CF card slot.

    • Lift up the CF card slot - in the 2nd photo you'll see a ribbon cable going through the slot to the front of the camera. We earlier disconnected this ribbon cable from its socket on the front of the main PCB.

    • Simply pull the ribbon cable out, but be sure to note the slot it goes through for later reassembly.

    • The 3rd photo shows the rear of the camera with the CF card slot removed.

    • Back on the top of the camera, gently pull the white connector with red/black wires out of the socket.

    • Now gently pull up the flex circuit and the socket away from the camera top

    • The 2nd photo shows the flex circuit and socket from the last step lifted away from the camera. This will now allow us to separate the plastic chassis of the camera from the lens module assembly in following steps...

    Добавить комментарий

    • Remove the 2 screws (rshown already removed - marked with red circles)

    • Now you can separate the plastic chassis on the right (battery compartment) from the lens module/flash/viewfinder assembly on the left.

    Добавить комментарий

    • Here's a view of the lens module/viewfinder/flash assembly (bottom) separated from main logic board/battery compartment (top)

    • At the bottom of the lens module assembly is the larger of 2 motors (yellow square) - this is the motor that extends/retracts the lens.

    • We now want to get to the geartrain driven by this motor to see what's causing the problem.

    Добавить комментарий

    • Remove the 3 screws shown here.

    • 2nd photo: After removing the screws, you can separate the electronic flash module (left) from the lens module (right)

    Добавить комментарий

    • Here is the electronic flash module.

    • **WARNING** there are very high voltage circuits involved in driving the flash. The capacitor (big black cylindrical item under the small circuit board) holds a large charge and could cause an electric shock - handle with care. Fortunately all the circuits here seem well insulated and there are no exposed high voltage contacts.

    Добавить комментарий

    • Here's a view of the lens module after removing the flash module. That's the optical viewfinder towards the right of the unit.

    Добавить комментарий

    • Remove the first of three screws fastening the optical viewfinder to the rest of the lens module...

    • ... then remove the second screw (2nd photo).

    • The optical viewfinder can be separated from the lens module - however it's still joined by a flat flex ciruit - be careful not to damage this flex circuit; just leave the viewfinder dangling to the side.

    Добавить комментарий

    • The geartrain for the lens retraction motor is inside this corner of the lens module.

    • (Note in this photo, the optical viewfinder is still attached to the right)

    • In the 2nd photo, viewed from another angle there's a hint of the lens retraction geartrain - the small white gear visible through a hole in the back. The lens retraction motor is highlighted with the yellow rectangle in the 2nd photo.

    Добавить комментарий

    • These 2 screws need to be removed before separating the lens module front and back halves.

    Добавить комментарий

    • Removing this small screw circled in red will free the small metal plate on this side of the lens module assembly.

    • In the 2nd photo the small plate is being removed.

    • You can now see the main large brass gear which drives the lens unit in and out, and also a slider/cam that zooms the optical viewfinder (yellow square)

    Добавить комментарий

    • By gently pulling apart the front and back halves of the lens module assembly, we expose a black gear and white gear connecting the larger brass gear to the motor

    • Using tweezers it's possible to remove the black gear without fully opening the lens module halves - just open wide enough like shown here to gain access.

    • Note: the flex circuits around the lens module are soldered and cannot be removed. Therefore you need to gently carefully move them aside when pulling apart the lens module.

    • On the right side of the photo, there's a small plastic piece with flex circuit attached. This piece is held by one of the screws and the front/back halves of the lens module. When reassembling it's a bit fiddly to get back in the right place if you're not paying attention.

    Добавить комментарий

    • Success!! by removing the small black gear in the previous photos, I was able to manually spin the big brass gear to extend & retract the lens.

    • Upon closer inspection I found some sand or grit in the black gear - it must have been jamming the geartrain, causing the E18 error.

    • With the gears cleaned, I could reassemble and test the camera. No more E18 error - the lens extended and retracted again normally.

    Добавить комментарий

    • Wait!... not so fast. After reassembling the camera, I found a huge piece of dust on the sensor in all the new images I took. Dust must have entered the lens module during disassembly. I had to take the camera apart completely again! This time, to open up and clean the lens module. :-(

    • So here is the lens module again, with the 2 halves pulled slightly apart to clean the sensor and/or inner lens elements. It was easier to disassemble the camera the 2nd time :-)

    Добавить комментарий

    • Here are the lens module with front and back halves separated. The sensor is under the rear lens element (yellow circle)

    • The optical viewfinder (top) and the front of the lens module (right) are also visible here.

    Добавить комментарий

    • In the rear half of the lens module, you can see some of the dust on the other side of the rear lens element in this photo. The sensor itself was clean.

    • This rear element is spring mounted and can be driven forward/back for focus by a second smaller motor.

    • The 2nd photo shows another view of the front half of the lens module.

    Добавить комментарий

    • Three screws (red circles, shown here already removed) hold the ring surrounding the rear lens element.

    • With the ring removed, you can gently lift up the spring mounted rear element (yellow circle) with tweezers. I was then able to clean out the offending dust on the back of the element.

    • Time to reassemble everything (again!) - this time, everything worked fine AND no more dust spots in the images. Success!

    • Here are all the components of my disassembled Canon PowerShot S500, excluding the battery and screws.

    • Reassembling the camera involves following the previous steps in reverse order.

Now I just got to figure out how to remove the battery door from my SX130is, I've got the replacement door and hopefully this guide will help me figure out which screws to undo to remove it....

Darren Forster - Ответить

This is, by far, the epitome of tutorials! Your images...perfect! Spelling...perfect! Content...perfect! I do a lot of writing and reading online and your work here is one of the best! Like you, I had nothing to lose tearing apart my Canon since it wouldn't open. I wanted something, anything, to guide me. I found your tutorial and wow! I followed your steps and it worked out. I'm going out now to take pictures with my Canon! Thank You!!
