No Display I have no display when the unit is open or closed and when the unit is open none of the buttons work.  The radio still plays fine but the remote doesn't always want to work either.

No display

Did you install the unit with the correct wiring harness, or cut-and-splice the wires from the factory line to the stereo lines? This could be a problem.

Won't switch to tuner

Sounds like the source button is not working properly. I have seen this type of problem caused by a crack in the display board. It can also be a bad contact on the source button.
Could be several other things as well, but most of the time it is something like a cracked board.
You can also try resetting the unit, look to see if there is a very small pin hole sized button on the display someplace, if so, use a paperclip or a toothpick, ect. to depress that switch. you might get lucky and the micro just needs to be reset. Sometimes you can reset a unit by disconecting the power wires for a few seconds, or just unplug the harness in the back for a short time.

Hope this helps

Car radio not working

Sound like you need the manual to this radio, I would have said that there are components inside that go bad that will cause a radio not to light up in the display area. But if you radio is saying tuner, and maybe cd then it would be the selector button that has a problem. Or no antenna is hooked up or come apart.

Illumination not working when faceplate is open.

Wire braid out to the faceplate has got a parcially broken wire on it. Sony referes to it as a flexible circuit board. Part can be purchased from sony directly, an on a one to 10 scale to replace about a five.But it does involve taking your radio apart. So if you are handy at electronics. you can look it over. If you have doubts let a professional do it.
