Buttons not reacting even after change of the battery

Buttons not reacting even after change of the battery

The display was there but the buttons were not working. I have unplugged, changed the battery but still nothing. It shows 1. 1. then 2103, then 0:00 and remains blinking. The buttons do not react.

"Take off the 5 screws on the bottom and carefully slide off the back assembly.

Take a voltage probe with the clock plugged in and check the power supply. By following the power wires into the PCB. The power solder joints should be above 5v even with a phone plugged into the usb charger.

Next i noticed that there was some kind of transient voltage across the back buttons of a few 100mV. This is incorrect. I tried to measure the current of one button to see if i could put the computer under an artificial button press. Next i noticed a different button came to 3.333V which is correct . I pressed it and it registered on the screen. Slowly but surely after I pressed the button with 3.333V others returned back to their proper voltage. Now all my buttons work.

This indicates ,to me: extreme static/noisy electricity, bad voltage regulators, or a weak capacitor somewhere."

"Someone on the Sony forum found the solution:

1- Remove the battery and unplug from the power source

2- leave the radio without battery and power for a minute or two

3- while pressing the ALARM RESET button conect to the power souce but do not install the battery

4- keep pressing the ALARM RESET button for another minute after pluging to the power outlet

5- Release the button, wait 5 seconds then set the radio according to your preference

6- after you are done setting the radio, re-install the battery

7- (Optional) if step # 3 doesnt work, press ALARM RESET and SLEEP buttons at the same time (you will see all the LED's turning on in the screen, and wont turn off until you remove the power source), unplug the radio, then proced to step #3

you should be good to go if you follow these steps.

Here's the link to it:

"Hey guys, struggled with this too, but found the answer on another forum.

Press and hold the TIME button or CLOCK button for more than 2 seconds, until two numbers flash on the screen.Change this number using the + and - buttons on the back to the correct year (20xx, where xx correspond to the year). Press the TIME button or CLOCK button.Enter the correct month and date (in this order for the EU version at least) using the + and - buttons, and press the TIME button or CLOCK button.Press the + button or the - button to select the time as required, then press the TIME button or the CLOCK button.

You can always start at 1 again if you incorrectly fill in the time/date/year."
