Kdc-bt61u face plate is black, not work, what to do ?

It's usually behind the face plate. Take off the face plate there should be a reset button, you will need a small pin to reset it. I also included a link to the manual for more help if needed.

you need to purchase the correct bus cable

it more than likely has bad solder connections inside the radio on some surface mount resistors usually located on the right front of the radio as it faces you.

These units are pretty cut, and dry.. Basicly the only thing you can check for yourself is connection. If the connection between the face plate, and the deck is good, and tight then you have one of 2 problems.
1) Bad face plate. Fix= $90-$130

2) Bad connection to the board on the radio Fix $60-$120

There is however a VERY off chance the processor is jumbled up, and wont cost you a dime to do a cold reset, so give it a shot.

To reset this unit simply remove the face plate, and locate the rest button. It is very small, but easy to find. Just use an ink pen or something of similar size to push the button.

MINE DID A SIMILAR THING THE FACE PLATE IS MOTORIZED AND GOT STUCK CLOSED SO INSTEAD OF BREAKING IT I FOUND THE RESET BUTTON ON THE RADIO IN THE FRONT ON THE SIDE ITS A LITTLE TINY BLACK HOLE STICK SAFETY PIN OR SOMETHING IN IT.BUT BE CAREFUL IF YOU DONT KNOW YOUR RADIOS SECURITY CODE IF NOT SURE WHILE STILL ON GO INTO THE OPTIONS AND TURN THE CODE ACCESS OFF.!

my problem as i think was same..
..problem actually not plate...it something inside...
repair guy just fixed something inside...as i understand some condinsators heats and after some pereod of time its broked by himself..so he first was thinking that it was plate but after it he foung the problem in this condensators....actually problem in tape and not in plate...

its the face plate just need to take out clean with little rubbing alcohol these kinda face plates has a scrolling feature that i donot like very much face plate just needs to adjusted back on sterio mount

Look for a small hole in the face plate. Take the tip of a pen and try holding it in for a few seconds. Re-setting it should work.....

If you have the remote control for the unit, or can buy one then you can reset the code. Just ask me how...
