AdiX I bought the strongest DUDU7 (DUDU7 12/512GB 360IC). First everything was fine and worked well after I setup the cameras. Then the front one started to vibrate and after it stopped working. I contacted with Tyler (Alibaba support) and we thought maybe the camera or the wire the problem but for sure I checked (it was Tyler idea) what happens if I switch the side cameras wires and the back camera wire. I have got the picture from every cameras except the front one (if I change it to the side the side was black screen, if the back then the back was black and so on...). So we thought the problem should come frome the front wire or from the front camera. First we changed the camera for a brand new one but it didn't help (still black screen) so then we changed the front wire too but it didn't solve the problem. Today the machine started working so strangely...it worked like I start to touch it continuously (like /in the old days/ sticky key on PC) on random points. When it stopped to do it I recognized that non of my cameras working anymore... just black screen from every cameras... I rebooted the machine, but of course it didn't help so after a few try I made a factory reset but I still have black screen. I tried to upload a video about it but looks like it too big or I don't know why I can't upload...[upl-image-preview url=https://forum.dudu-auto.com/assets/files/2025-03-26/1743022762-172979-img-0582.png
dudu-lai AdiX A faulty camera will cause the rest of the cameras to go black (but not damaged). Have you replaced the front camera, the front cable, and the B-zone connector?
YAOXILONG Unfortunately, it seems that there may be a hardware failure. If all the current cameras are not working, try to remove all the cameras and see if the device is working normally. Next contact after-sales services.
AdiX dudu-lai I don't know what is B Zone connector. I tried switching, reconnecting, all the cameras and that main connector too which collects all the cameras connectors and bring them into the headunit (maybe is this B Zone connector?) the front camera and extension cord are brand new.
AdiX It's all started with a little vibrating on the front and then I had black screen for all. Then it tried to start and crash continuously. After a factory reset it stopped it. With the new 3.5 OS 3 cameras of the 4 started to work... Tyler said to me check what if I change the cameras wires. All the cameras worked well wherever I plugged them. The front was the only one with black screen. I got a new one and when it arrived the original camera started to work but after a few days again stopped. Then I changed it for the new but I still have black screen. After it I changed the front wire extension cord too for a brand new one...still black screen. After a few months using about a weeks ago all of my cameras stopped working... and now I still have black screen.
AdiX AdiX This is an example when I switch the front wire with the right (not my idea! The support, Tyler asked me for that!)
Wanted Did you solve the problem? The same thing happens with my radio. Please tell me how you solved it.
AdiX Wanted Not yet. I changed all the cables, tried the cameras too... The only last try is that collector main cable/wire what you can see above. Funny because the car is at my electronic specialist right today. I will write what happened. I contacted with other experts too and we have an idea...the heat ruined the 360 chip soldering (because it was a poor quality) so I need somebody and maybe you too who can replace the chip. Hopefully just the soldering melted and nothing bigger problem happened with the chip.
AdiX Wanted Yes! We replaced the original headunit with the brand new one and we have the same problem. It's insane... So we have to think that the original front camera broke and the second one what I got in warranty came already broken... I don't know what is the chance for that but looks like after a year and a lot of money (2 pieces of Duduauto 7 12/512) finally we will find the problem... I'm so angry, but what can I do?! I hope I will get a nice compensation because this extremely big mistake...of course the biggest question is still that can this be true?! Insane... I will write here after the support help me... it's easily can be 1 month... better if I say nothing now... just think...1 year...more than 1K $...
