1.5 kV power supply for LASERS?

Hi all,

I've just bought two "real" lasers but a few hours ago one of the two power supplies smoked up, I don't have the schematic because the I can't open the boxes of the supplies.

Does someone know where to find quickly a schematic of a 230V to 1.5 kV power supply? I hope I can repair this soon, because I've promised an amazing laser show over two weeks :).

Thanks anyway.

Best regards,
