a1181

I have a MacBook A1181, i bought it second hand back in 2020, at first it was working fine but after a while it suddenly won't boot, it's stuck at the apple logo progress bar, it won't let me boot into recovery mode, safe mode, and i tried resetting the NVRAM, tried all sorts of stuff to get it...

I replaced the LCD screen of my laptop to fix a burnt out backlight bulb issue, but now when I turn on the computer it stays at a blank blue screen. I've tried resetting the PRAM and it stays blue trying to hold down the command keys too. I inserted my OS installation disk and nothing still...
