macbook pro m3 display furry blurry not work with external monitor

My MacBook Pro M3 (14-inch ,nov,2023) when the display suddenly went completely blurry and empty blank .There’s no physical damage, dents, or drops — it just stopped showing anything while I was using it.

when I connect it to an external monitor (display)by Hdmi port to connected to macbook then show external display also blurry not work at all . This makes me believe the issue might be with the built-in display or possibly related to the recent macOS update, which I installed just before this happened.

everything is working properly like keyboard (light on )cap lock green show ,mouse and charging is also work . macbook lid open are also apple logo show but blurry screen . i can see on screen with blurry SMS , masOS reinstall , disk utility but see properly 100% blurry .my warranty is expired , how many cost such that problem.

this also one time before 1 day then automatically correction black blurry screen then i charging complete , leaves it 6-8 hour

Has anyone else faced a similar issue after the update or found a fix for it?

Any help or suggestions would be greatly appreciated.

MacBook Pro 14″, macOS 26.6

If the external monitor is showing the same fault as the internal display— you would expect this is a GPU issue...

the resolve would be a logic board replacement.
