I have several or even a dozen radios from Mercedes NTG5s1.

In each of them, after switching on, the power consumption increases from 0.2 to 0.6 A. The internal fan turns on and nothing else. Nothing is displayed on the monitor. The defect looks like a standard one because every second used radio has such symptoms.

I can't flash the radio in DOIP. DTS Monaco via DOIP can't see radio communication. In its normal form, this radio on the table along with the monitor draws about 1.5 A.

Has anyone met with this fault? How to fix it ?


Sorry for my English
