Your description indicates damage caused by an electrostatic discharge. For this cases it’s not easy to tell the amount of damage or which components are even damaged.
Your described behaviour (blank LCD with backlight on and no output) is the standard behaviour for a OSSC with no firmware. So maybe(!) your FPGA(??) or the flash memory was damaged???
If you want to try a repair yourself i would recommend buying a USB Blaster, connecting your OSSC via USB Blaster to a computer and try to flash a firmware onto your OSSC like it’s described here:

If the Quartus Prime software is able to talk to the OSSC, then there’s at least some hope for a doable repair. But if it fails, there may be some major damages to the main IC…
