Faceplate and power button.

There doesn't appear to be a setting which will change the brightness of the faceplate. Though some radios will change brightness when the headlights are on or off.

You could try resetting it by pushing the RESET button on the back of the faceplate.

THE FACEPLATE HAS LIKE SOME PINS WHERE IT MAKES CONTACT THE FACE PLATE WITH THE STEREO BODY WITH A COTTON AND SOME ALCOHOL CLEAN THE CONECTOR THE ONES THAT ARE IN THE STEREO BODY AND THE FACE PLATE BUT WHEN YOU MAKE IT MAKE SURE THE CAR OR FACE ITS TURN OFF

Sony car radio cdxgt540ui buttons non responsive - remove four screws on reverse side of faceplate, pry open with fingernails starting at the top right or left corner of the face plate once opened remove board on the reverse side of the LCD there are small brackets holding the LCD use a needle nose to pry each bracket in straight position then remove LCD for ten seconds then place back on to board and been brackets back in place. After these steps the front buttons should work again this process worked for me.

Try removing the face plate and pressing the button from underneath where the power button is. It is possible that the piece on the faceplate that presses the "actual" button has broken off. The face plate is removable.

I would try cleaning the connectors on the face plate with an pencil eraser and on the unit itself with a very fine sand paper. And make sure you get rid of any dust after cleaning before putting the face plate back on.
Please leave me a good feedback.
Thanks

How do I mount the Face Plate on the Latch?

Insert the latch into the faceplate opening, ensuring that the sides of the faceplate line up with the flat surface on the latch collar. Push flush with the drive-in collar. Then grasp the faceplate in one hand and the latch in the other hand and rotate the faceplate clockwise to snap in to the collar.

check the gold contacts on the back of the face and the unit also check the release mechanism theres a little black button (not the reset) that when face is pressed up against it it activates power to the gold contacts thus powering the buttons

The capacitors in these plates tend to burn out quickly for being so hot and lack of air cooling circulation. You can test all connection pins on the deck and faceplate with an ohmmeter in ohm setting to see which pins is not sending 25-30 ohms or 5 volts of power

The faceplate may have a bent pin, or is not fully clicking into place.

Before getting all worked up, try pressing the release button to remove the face plate and carefully inspecting the areas where they click into the main unit, small pieces of debris may be stuck in the clips, if this is not the case, carefully re-insert the face plate, making sure to have aligned the guides before pressing the face plate back into place. You should hear a nice confirming click when the face plate is in place.

Bent pin or contact, can easily be spotted by grabbing a magnifying glass and looking at the allignment of each pin, take extra care when straightening the pin if this is the case.

**Tip**
Most solutions can come from closer inspection ...
ie: with a magnifying glass.
