This tutorial will show you how to disassemble a canon a540/a530 to the sensor to remove the ir cut filter.
Tools:
#00 philips screw driver
soldering iron
couple of notes:
- there is 300 volts or so inside the camera. canon has done a pretty good job shielding those areas, and I haven't gotten shocked even though my fingers have been everywhere, but be careful anyway. it's enough energy to kill you several times if you're unlucky.
- you may end up with an ir sensitive camera, or you may end up buying a new camera.

remove the green and red screws. the green screws are identical. take off the back cover. the back cover snaps together with the front cover at the top of the camera.

remove the screw and take off the front cover. there's a thin dust ring between the cover and the lens barrel, don't lose it.

remove the screws. the red screw is a metal screw. pry off the plastic io panel and tripod thread assembly.

if you want to, now is the time to turn back
first remove the two screws holding the control panel pcb, then disconnect and remove the control panel. very carefully disconnect the cables. the connectors are very delicate, and if you snap one, you'll be buying a new camera. | Byte size: ZERO | Content warning: NOT AN IMAGE |
desolder the circled wires. it is not necessary to detach the crossed wires. remove the three screws holding the main pcb (not indicated here), and reflect the main pcb along the bottom, exposing the sensor.
