Default Blown backlight on Pioneer DEQ 99

I managed to wire up the polarity wrong on a DEQ 99, and I appear to have blown the backlight part of the circuit... The main part still works but there is no display.

The circuit used to do 200Vac at 1KHz, which powers the display on the headunit.

What would be the easiest way of fixing this? Would it be worth getting a separate inverter and wiring it to the backlight?

Have you opened it up and looked for open traces or open fuses (which may not look like a common fuse - likely marked FUxxx)?
