My macbook’s screen is smashed along with the LCD and this means that I cannot see what is on the screen, logically I thought plugging it into an external monitor would fix this issue however to no avail in the HDMI port and both thunderbolt ports (I checked to see if the USB’s were working and they appeared to be). The MacBook’s backlight is working and there is no liquid damage present on the logic board. The caps lock key lights up but the keyboard backlight does not work. When powering on the machine it chimes but I cannot see what is on the screen because of the damage. I have tried resetting NVRAM and PRAM and SMC but none of these worked. Any help?
Either your external display and its connection is not configured properly or the logic board still has an issue. Did you validate the display setup using another Mac system? Basically are you sure it works. How about posting a few pics so we can see the physical damage Adding images to an existing question so we can check out if there is still something more effecting things.
