Youll need better pics if you want help. Generally the ones with the pins in a line are the IR diodes, which are rectangular in shape.

The other diode (with three pins in a triangle) are circular in shape and can be either an IR, red or dual wavelength diode. This is the diode you will need. Have a look at DTRs website and order a copper module for the size of diode you have. Laptop drives often, but not always, have 3.8 mm diodes and desktop burners are more than likely 5.6 mm ones. Measure the diode and order the correct copper module. Good luck! :beer:
