Hello, I have note 9 sm n960u and its not turning on completely dead. No light no vibration nothing. I have tried all troubleshooting steps tried many different cable wireless chargers and everything i possibly could so to fix it but it wont respond. As this device was bought in US and i am not in US any more so i cant send it to service center so i went to a local repair shop and the guy there told me thats its the board dead. Now i have no idea what to do as the device was running perfectly when i kept it aside after complete discharge. I would be glad if anyone can help me with hardware based trouble shooting. I still havent tried new battery as the guy told be thats its with motherboard so should i trust him or try a new battery? Is there any way i can check shortage with multimeter to confirm myself? I would be happpy if someone help me out witht this
@mustaqeem the instructions from My battery died to 0% and won’t charge now, wired nor wireless. would only work if your battery was discharged below its charging threshold. It will not fix a battery. My suggestion would be that you start with a new battery. Your battery may have shown a proper voltage but may not accept a load or fail under a load. Replacing the battery will at least give you a known well starting point should further troubleshooting be needed. Check this teardown Samsung Galaxy Note9 Teardown to see what is involved with that.
