Hi, I have bought Raspberry Pi 3 Model B a few years ago. At first, it works well and then it was unused for years. When I try to power it on it shows only a red led. I have tried several ways. But not work. Last night I have tried to power using Xiaomi Redmi 10 mobile charger, but now it shows no led. I have gone to a mechanic for a test and he said, the power is not flowing all over the circuit but 5v is still getting. So, the device is dead?
