Hi there and welcome to Just Answer, my name is ***** ***** I look forward to helping you.
I’m sorry to hear you're having trouble. I know that can be frustrating. Hopefully, we can get this resolved quickly.
Please disconnect the power cable to the computer then hold the power button in for 60 seconds then release.
Then connect the power cable, power it on and tell me how it now functions.
Please let me know the results.
Thank you

If you disconnect the screen, does it say no signal?

It is the internal motherboard that has faulted.

I am really sorry about this and you are going to have to return the computer to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.

I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.

Thank you
