My printer no longer turns on

[ryanPIveta]

Hello good afternoon. I had changed the extruder nozzle and turned it on normally, but I had forgotten to connect the extruder power cable. I turned it off and connected it, but when I turned it on, the screen didn't turn on anymore, the source works, the power is correct but it doesn't turn on anymore. what should I do?

Hi ,

Thanks for your feedback. How does the light at the motherboard react?

[ryanPIveta]

Good afternoon. Sorry to answer so late. The motherboard just turns on its LED light and nothing else is activated.

Hi，

Whether the light is turned on as soon as the power is turned on, or when a heating command is sent

[ryanPIveta]

Good evening.

As soon as the power is turned on. But nothing but this led turns on. Neither the coolers, nor the panel. Anything

I have a similar problem. In my BIQU BX printer, after connecting the HDMI cable to the hotend, the printer does not respond. The screen is black, the USB is not communicating with the computer. The red LED on the board was on for some time, but not anymore. The CPU heat sink was also warm in the beginning, not now. The LEDs on the touchscreen (on the other side) light up: red and green. The fans are not working. The 24V power supply works.
