Hey
I made a lithium ion based battery pack and by mistake supplied the Raspberry Pi 4 model B with 9V 3A supply via a buck converter regulator. As soon as I connected Pi with the 9V supply the red PWR light came ON but this time unusually only RED light came ON and the green ACT light did not come ON. I realised that quickly and removed the 9V 3A supply. Now after realising that the pi needs only 5.1V 3A supply I again supplied the Pi with 5.1V 3A supply...this time also only Red PWR light comes ON and ACT green light shows no response....also one more thing I noticed is that the raspberry Pi 4 board is getting really Hot near the ethernet port area. I think the raspberry Pi board has shorted the current path... Please help ... Maybe the board has gone in protection mode so the power input is shorted. Please help.can the board be Reset? Is there a hard reset option.... everything on board looks fine...no noticable damage on board
