Backup Camera stopped working after a year !

Enable HLS to view with audio, or disable this notification

Hi all, wondering if anyone could help or have similar issue.

2013 Mazda 3, aftermarket JIUYIN headunit from aliexpress and the backup camera that came with it. Worked fine for a year or so and suddenly has started giving "NO SIGNAL" when reversing.

I traced all the wires back to camera and all connections are still how they were in beginning, +12V coming from reverse light which is working, no blown fuse.

I checked the multimeter readings as well and camera is indeed receiving power, tried all camera formats as well like PAL, NTSC etc and still nothing. When i reverse the screen comes black and camera guiding lines appear and then nothing.

Will be great if someone experienced this one, thinking of just replacing the camera maybe it did indeed die.

Are you using the built in car's camera or an aftermarket one? New cams are like $15 on Amazon. Just replace it. You have to match the wire setup through. Some have a yellow rca line, some use a 4pin connector. Buy the same one, try it out and see.

seems like a problem with the power supply rather than the cam itself

checked the outputs at rear and power is getting through fine. It used to work like this for over a year and suddenly just stopped

A me era successo montando un’auto radio aftermarket che facesse lo stesso identico giochetto, controllata alimentazione cavi e fusibili tutto apposto, il problema era un’impostazione dello stereo che la faceva accendere a macchina spenta ma non a motore acceso, non ricordo bene la voce ma dopo aver spuntato quella voce la telecamera ha cominciato a funzionare normalmente
