It may have shorted out backlight circuits or problem in the 18~24vdc power supply section, the 5vdc is working though. It can also be the main logic board itself.

Having trouble with an aftermarket radio hrness in a 2001 saturn sl it wont turn on what can i do


the only 2 wires you dont want to cross are red and black . once you have red from radio red from harness, black from radio black from harness connected it should light up ..the speaker wires can be "trial and error" . if red and black together dosent light it up check the fuse on the radio and on incoming red wire. try bringing 2 wires straight from the battery with a fuse between the red one to radio,if it dosent light up then with "direct power " then the radio needs to come apart to see ether internal fuse or burnt our circuit. ps: sometimes you only need to connect the red "live" wire and touch the black on the casing of the radio to test for life.

try unplugging the power cord from the ps3 and putting it back on. if that doesnt work, your console might have kicked a breaker in your homes breaker box. on the ps3, always turn it off by the the back power switch.
