I am using Raspberry pi 3 as media center with OSMC on it, it was working fine with 5.2V 2A power supply for about 3 months.
But now LAN and USB ports are not working, green LED is also not blinking on boot, but I am getting output on HDMI (though it takes more time to boot). The display on my TV shows low power symbol but I think 2A supply should be sufficient for pi without any peripherals connected. I have disconnected everything form the board (only power supply and SD card connected) but still same results.
I checked voltage output on GPIO pins and I am getting ~5.1 V and 3.24 V on pin number 2 and 1 respectively. I also tested voltage at PP7 , PP35 and PP8 all seems fine. PolyFuse also seems good.
So far I have tried latest version of OSMC, Raspbian (without NOOBS) on SandDisk ultra 16GB class 10 Sdcard, and tested these power adapters ( 5.2V 2A , 5.1V 1.5A ) .
Please let me know what can I do to narrow down the issue.
