Hi, I got a Samsung A41 (SM-A415F) that drives me crazy: It doesn't charge anymore. After reconnecting the USB board, charging was possible for only a short time. I replaced the battery and the phone still doesn't charge. As seen in a video (https://www.youtube.com/watch?v=tm5_fsrAkHA), measuring between GND and the flex cable brings exactly 5.00 VDC. The board in this device supplies as much as about 7.00 VDC. I bought a new USB board including new flex cable and this provided "naked" 5.6 VDC. After using in the phone, the output voltage also increased to about 7.00 VDC. Is it likely that there's a problem with the power IC (U5005) on the main board?
(Will remove the heatshield to gain more measurements but I have to make sure that the owner has a backup as long as it turns on.)
Thanks!
Nico
