Hello,
No power on
The battery is good
I have the schematics.
The command that switches from 5.3V to 0 works well on input 66 of IC 601 (PE5518A)
No LCD lighting and no sound from the speaker
What other points should be checked?
Thank you

Configuration: Linux / Chrome 47.0.2526.106

    Good evening,

    First of all, it would be good to know how this car radio was connected and which car it is from.

    Good evening
    I have all the diagrams and I have correctly connected the inputs of this device. It has been tested on Peugeot 306 and Renault R11, but the vehicle doesn't matter.
    I am currently troubleshooting: I am an electrotechnical engineer but do not have the skills and experience of a pure electronics expert, especially in this field.
    Thank you and ready to receive any advice
    Best regards

    Well no, it's exactly that, it doesn't matter what vehicle...

    And "I've correctly connected the inputs of this device", it seems that's not the case since it doesn't work!

    How did you connect it?

    With ISO connectors suitable for the car and the car radio?

    By stripping the wires and connecting them one by one?

    I'm neither an electrical engineer nor an electronics technician, and this case has nothing to do with either of these two fields.

    I reiterate my question:

    By what means is this car radio connected? And what is the car it is connected to?

    Hello "STARGATE 43"
    Don't worry about the "engineer" !! He just detected a "bad solder joint on the Key Board connector and everything is back to normal
    To answer your question clearly, this unit is no longer in a car but is being used in my workshop connected to a small 12V telecom battery.
    Anyway, thank you
    Best regards

      Hi,

      Well, you didn't specify that this car radio wasn't installed in a car ;-)

      In the end, all's well that ends well if you've found the cause of the malfunction ;-)

      No problem, my pleasure ;-)

      Best regards and enjoy your listening ;-)
