Hey mine did the same thing on thursday the 28. I had the battery off cuz i was working on the engine (misfire of cylinder 4) and when I plugged my battery back my deck wouldn't turn on. Mines a 700bt. I just get a black screen. No pioneer splash screen. And like urs the lights turn on and the fan kicks in. So it looks like it's on... but the screen is just black.... havn't found a fix tho...sadly... ;( I tried doing a hard reset... but all it does is the lights on the unit pulsate... and then within 30sec the light turn off of the unit.
