Question about Kenwood Kdc448u
Used continuity tester to test fuse on radio, ground, remote wire, etc... all have power. Power is running back to the amp for the subs as well BUT the actual stereo unit has no power. No red flashing light (when you take the face plate off that light that blinks) and the face plate has no power. Just had the engine swapped out and it worked perfect before hand. Car sat for about a week or so with no battery in it I dont see this being a problem? It worked perfect until now. What the H
If you are sure that the unit has power, try resetting the unit. The reset button is on the left of the plug behind the faceplate.

SOURCE: power to stereo none to unit
There is a ribbon cable that goes from the display to the main board of the radio that may be bad, if you have everything connected properly and all you get is the red led, this is a possibility. No way for anybody to know if you have it wired wrong if they can not look at it themself.
The red wire is for power when the key is on, the yellow wire should get power all the time, the black wire is ground.
If you have those correct, the radio should at least turn on. If you have these right, you may need a new ribbon cable. The connector that interfaces with the detachable face must also be taken off the old ribbon cable and put on the new one, or get a new connector and just replace it. The ribbon cable does not come with that connector. It is soldered on the ribbon cable, so if you are not very good with a soldering iron, you should have a service center do it for you.
Let me know if you want the part number for the ribbon cable and/or connector, I can get those for you.
I can not guarantee that the ribbon cable is the problem, or that it is the only problem, but it is the most likely problem with that model number of Kenwood. I have repaired many of them, so I have a good idea what causes most of the problems, but I have seen times when the usual suspect is not the problem and something else like the LCD in the face is bad, or the IC that controls the display is bad. Even a voltage regulator on the main board of the radio can be at fault as well. There are probably about 10 different things that can cause that one problem, having an experienced technician is always the best way to determan the problem with certainty.
Let me know if I can be any more help for you.

The speaker wires are very sensitive. You need to make sure that they are not grounding out. Once the unit senses this it will shut off. Pull the plug out of the back and start over.

Look at the enwood. I bet you have the remote wire hooked to the blue wire insted of the blue/white wire. The blue wire goes dad when you play a cd as it is for a power antenna. The blue/white wire is your amp turn on.
Now, if you do not have a blue/whie and only blue, then obviously that circuit in the radio is bad in whch case your only other option s are either connecting it to an accesory fuse or using a toggle switch connected to power.
