A lot of electronic and electric stuff are often pretty easy to
fix. Sometimes it isn't even an electrical problem but more a
mechanical one. Below you will find some general tips when doing
repair work on electronic devices. Also check out my
repairblog
pages where I describe all repair cases I come in connection
with.
When doing repairwork on remote controls it is very useful to
have a digital camera. With this you can directly see if the IR
diode is working or not. As you can see on the picture, the IR
diode shines brightly when viewed through the digital camera. A
video camera will most often also work. This is because the CCD
device in the camera is sensitive not only to visible light but
also to IR light. This is supposed to be filtered out with an
optical filter but the intense light from an IR diode in a
remote control will shine through anyway.
