just wanna ask my monitor suddenly goes black while gaming upon monitoring it I saw that it's displaying something but very dim upon research I saw that it's an issue about backlight I was hoping to know if I buying a new backlight would solve my case my backlight is working lighting up

I'd first try another monitor in order to verify that the monitor is the problem. Any number of things could make it go black, other than the monitor.

Much less expensive to simply purchase a new monitor. The backlight assembly (likely LED) is part of the display panel and not independently replaceable. The cost of panel replacement (parts & labor) would be very close to replacement cost, and you get a warranty with a new monitor.
