Troubleshooting Anet A8 Mobo

Hello! My Anet A8 printer recently been acting weird... on the monitor its displaying incorrect temp for the bed and the hot end. its displaying that the hot end is at 178-180 °C and 104-105 °C for the bed, even though the parts are room temp. What i have tried:

1. Reboot- nothing changes
2. Disconnected both sensors, restarted the machine - no changes
3. I upgraded its firmware - yet again no changes BTW I have noticed that that the purple mosfet is getting really hot ~ 90 °C, the blue one is getting to ~60 °C , and the main chip is getting really warm as well...

4. I also tried cooling the mosfets - no changes as usual... Any tips / ideas what could be happening here?
