head unit wont turn on

i have a jensen 3010x head unit and ive been trying to install an amp with it and i havent finished that project but now my head unit will not turn on at all, but the little power button is lit up so i know its getting power but when i press it  nothing happens, it also wont eject the cd thats in there. i unhooked all the rca cables and remote turn on wire that was coming from the amp and im still getting nothing, whats wrong?

thanks

First thing, i know this is silly but you never know. DO YOU HAVE YOUR KEY IN THE CAR AND TURNED TO ACC.?

Forget about all the wires accept the YELLOW, RED, and BLACK wires, those are the power.Make sure you install them correctly. Check the fuse on the back of your Head-Unit, also there's a fuse on your fuse box (somewhere in your car) for the OEM unit aswell. If that does not solve your problem. might want to use the volt meter to see you're getting any power in. If so, then your head unit got problem....hmmm get a new one i guess or return it if you just got it.

Are you using an amplifier or are you connecting your speakers directly to the head unit?

If you have an amplifier, check that you have the remote turn on lead of the amplifier connected to the amp remote lead of the head unit and that you have the amplifier's main power lead connected to the positive side of the battery and not some other 12V+ source (ie: ignition). 

If you have your speakers connected to the head unit, make sure you have the memory lead of the head unit (usually yellow) connected to a constant 12V+ source (ie: positive side of battery) and not to the ignition as you could possibly have it from what you described.

hahaha...sounds like you have loosely speaker wires connected. probably the same reason the fuse blew. Spend a few bucks buy those wire connectors (not sure the exact name but you know what i'm talking about) Make every wire connections clean and tight.

try that and let me know.
