A faulty LCD screen is easy to replace. If you have a stuck lens, complete lens assemblies have been seen on eBay for around £25 and can be fitted quite easily. If you have unreliable buttons, you may be able to cannibalise the parts from another camera of the same model with a different fault.
Disassembly of the lens is an advanced operation only to be undertaken if you have a flair for understanding intricate mechanisms and can devote as much time as it takes. At the end of the guide I simply share a few key tips to get you started.
The only essential tool is a small cross-head precision screwdriver. It's essential to remember which screws came from where. You can use a couple of 7-day pill boxes, noting which compartments contain the screws from which steps, or stick the screws to a piece of paper with Blu-tack, noting the step number against each.
This camera contains many ribbon cables which need to be disconnected and reconnected. theThe connectors are of 3 types:
* In most, the end of the ribbon simply pushes into a socket. Usually, there are rigid tabs on either side of the ribbon which you can pull or push on with a small flat screwdriver, and/or a hole in the centre of the ribbon which you can get some purchase on with a tiny flat screwdriver. (Don't use a pin or other sharp object as you might scratch and sever a trace on a circuit board underneath.)
* Just one ribbon is like the previous type but there's a black clamping bar which must be lifted with your fingernail in order to release the cable. Make sure it's up before trying to reinsert the ribbon.
* Several ribbons (on the main logic board) use snap-on connectors. Pull them off with a fingernail under a corner. When you reconnect them, ensure they are correctly aligned and press firmly. They should snap home quite positively.
