So I have a 2005 TSX and I removed the radio to swap for a NAV unit but I noticed one of the cables required for the NAV unit wasn’t there so I just put the old one back. Now the Radio won’t come on, Clock keeps blinking, The A/C or heater thing works fine. The fuse for the cigarette lighter blew while doing this, but i changed it. I have checked fuse 6 and changed it and no luck. The anti-theft light won’t turn on on this one but would turn on with the other one. Is it broken by any chance? Or is it a simple fix? Please help ASAP

Sounds like you know how the anti-theft works.

I would remove and re-seat the electrical connectors. Check them for any pins that are bent, pushed deeper into the connectors, etc.

It's probably a connector/pin issue but worst case it's possible that you cracked a solder connection on the circuit board... inspect where the connectors on the board are soldered to it, look for cracks which will usually appear as a thin, dark ring in the solder around the wire. If you suspect cracked solder, I'd probably take it to an electronic repair place to get re-soldered... soldering small electronics isn't easy, I've been soldering stuff my whole life and I wouldn't try it on something with a lot of small connections close together.

I just removed it again and checked everything and everything is fine. No bent pins, no cracks, nothing. Is there any other thing that it may be? I just noticed the Anti-Theft light does turn on when the car is off which is probably the only time it should be on so i’m wondering what could it be.

Edit: It was literally the most simple fix… The power button just wasn’t pressing down all the way down so it wouldn’t turn on…

Always verify that the Oh En / Oh Eff Eff selector is in the Oh En position

It might be internal fuse blown on the board inside the radio. That thing takes time to openup and check. Check the power that goes to radio on the power connector with multimeter. You can find diagram on web. Usually its red and black wire.
