Do you know the power supply is working? If you have a multimeter, check that it is putting out 12V as expected.

muksys wrote:The way to check the voltages is to stick the black probe on tp11 or 13 and use the red to test the different voltages. Positive voltages will read 12, 9 or 5. Negative voltages will read -9. Make sure you have the probes plugged into their corrisponding terminals on the meter. The black should be plugged into to COM port.

Just a clarification, this resistor should be 4.99 ohms, at least according to the schematic (and the resistor itself looks to be marked 4R99).
With the power supply plugged in, put the ground lead (black) of your meter on a ground test point. Then put the red lead first on the left terminal of the resistor and measure DC volts. It should be around 12V. Then move the red lead to the right end of the resistor. It should still be around 12V.
