black screen and no sound but led turns blue when switched on and flashes when remolt button pressed?

Any ideas?

The firmware in your spi flash 25Q32 may be damaged, you can read the contents (dump) with the programmer and post it here.

Do you have a programmer, if so, read its (spi flash 25Q32) contents (dump) and post it here.
