Moving head light- 24 volt 250 watt lamp driver

[joshua17ss2]

I Have a DMX 680 Moving head light, The lamp driver in it is a 24 volt 250 watt, (halogen) driver, I think its halogen. A component has i guess overheated due to use, and this has caused the light to stop lighting. I am trying to identify the component so i can make a new one or buy a replacement, I have chipped it apart since it was a sealed resin, 5 pins, that connected to the board, i have found 2 transistors, one marked 2n5551, 3 capacitors, 2 were 50 v 10 uf, a smaller capacitor, and a I think a tantrum capacitor, there were 2 resistors and a diode. I took a few pictures that might help.

Any help would be appreciated
