Hmm, can anyone help me figure out what happened to my head unit? January 17, 2007, 11:50:02 PM Here's the basic story:When I put my bird away for the winter back in october-ish, my CD player (a Sony Xplod one I've had for about 3 years) was working fine.Over the past couple weeks I've been kinda tearing into the dash, pulled out the gauge cluster etc. Just last week or so, I was doing something which involved having the key in the "accessory" position, and it dawned on me that the CD player had not come on. I pulled it out of the dash and looked at the wiring, and everything seemed to be in order...so I removed the face to see if there was something wrong with the connection there, and put it back on. It flickered on for a split second, spat out the CD that was in the player, and now I can't get any signs of life out of it whatsoever. I plan to check the wiring to see if there's any shorts, but I can't figure out what could have happened. Where I spliced the adapter harness into the CD player harness, I ziptied all the wires together to prevent any of them from getting messed up, and I've NEVER had a problem with it before.I'm actually wondering if maybe my CD player finally bit the dust, I was having some problems with it here and there last summer where the display would just go off for no reason and come back on.

A spare computer power supply works great, just short one wire in the 20/24 pin atx plug to ground to power it on and you have a cheap 12v psu (will be more like 10.5v without a load on 5v, but whatever).

Or it could be in the wiring. I think it is sony the makes there radios where the display/unit won't come on unless both power wires are hooked up. This could be you problem. Also maybe the battery is under the minimum voltage that the unit will let it turn on with. Quote Selected

Reply #6 – January 18, 2007, 10:43:49 AM Fuse is good, that was the first thing I checked.Besides, I knew the fuse wasn't the culprit when it had its little flicker of power there, unless the fuse blew at that moment but I don't think so.

Apparently the factory ground in the stereo harness, which I've used ever since I put a CD player in the car, decided it didn't want to ground anymore I hooked the CD player ground to one of the pieces of metal in the dash and voila, it works again.Odd.

Reply #9 – January 23, 2007, 11:25:47 PM stupid common ground..yeah, that too happened to me.. watch out your main power will go next man.. im runnin a new ground from the dash braces.. and memory directly from the battery and the power on is still working through the ignition.
