Display Backlighting Repair
I have an old 2003 Nissan car. The light on the clock/radio never worked from purchase (also the shifter light). The original lights used to light the front panel of the radio were of an incandescent type and soldered surface-mount to the PCB, really annoying. I decided on replacing the lights with surface-mount LEDs. The front panel lights are powered from the car itself, not from the radio.
I got this receiver for free from someone who did not want it anymore. It was in pieces because they attempted to fix it. This is a successful repair.
