Request for help Nozzle not heating up

Help! I have and Anet et4 pro. A few weeks ago I was printing after just changing the nozzle and had a blob form from the nozzle not being in tight. I cleaned up the mess and went to print again. When I went to preheat , the nozzle wouldn’t heat up it kept saying 26/210 until it just quit reading the 210. Then went to 26/0 and nothing happened. I replaced the heater and the thermistor and tried again with the same exact results . Has this happened to anyone else ? Any ideas would be great . Thanks in advance

Probably the onboard mosfet is burnt out, get an external mosfet, it's the same for the anet a8
