It made a loud-ish POP noise and weird, heavy smoke came out from underneath, like a puddle. It’s probably unfixable, but I’ll give it free to anyone willing to try! It cost me nearly £300 and I could have wept when it happened, after I realised about needing a transformer, etc…
ailsa.laing the part that usually fails by receiving an over-voltage is the power supply. The pop and smoke is most certainly coming from the caps on the board. Consider replacing the complete power supply with on that supports your voltage. Part number for that is LT0485001 and you can download the service manual from here
