car radio CD:98067084XT
display:9801219480-01
The button for turning on the device does not respond and the display is black - there is nothing. I have given a description of the measurements in the picture, only the voltage on the white wire is sometimes 5V and sometimes it is 12V. Only the background light on the device works when the position is turned on. The customer says that the display works occasionally and then the device works normally.
Please help me, what should I do next?
Greeting!
