Hi have been having issues with my Garmin 55 dash cam for a while now, and almost about to get a new one, but i thought I'd try to troubleshoot this. Bit of background history. I don't have the camera for very long, approaching just over a year and purchased it brand new online. The camera was working fine for a while, but I did get a corrupt SD card message, which upon research, proved to be a memory card issue that came with the device.

I since have changed it and no issues ... for a while. Recently a new issue has come up ... Distorted live recording.

This happens randomly, whereby the the image is completely half black and purple almost; completely unusable. I have attached a screenshot of the video recording. Turning off and on the dash cam does not help, and as I said, it randomly comes like this now and then. Lately it has become a daily occurrence, to a point where the camera is useless. Version and serial are in the attachments.

I thought it may be another SD card issue, but I have recently tried two brand new SD card (compatible, i made sure with the camera) and the problem is still there.

I've also used Garmin Express to upgrade to the latest firmware/software, ver. 4.40, but still makes no difference.

I've almost given up all hope and about to purchase a new camera, but thought I'd try to ask the community if anyone out there has received or experienced similar issues. Please let me know and how you went about resolving this.

Much appreciated.

Too many ¯\_(ツ)_/¯
the CMOS sensor looks to be failing, not something you could repair if it is mounted directly to the PCB, would need to see it opened up to confirm if that's the case

if the sensor is mounted directly to the mainboard there's nothing you could DIY, if it's on a separate board you can check the connection between the two, a bad connection can cause a similar result to a failing sensor, haven't seen inside one of these but the form factor is typical of a single board design so may be out of luck for any chance of a DIY fix

Thank you ... i'll try to remove the coverings without any damage, and will attempt to take any photos that may help. Many thanks for your help. i'm guessing this may be the problem.
