Vizio BV47L FHDTV10A has a blown power supply

Question

Contacted Vizio, reported that there was a loud crack and flash accross the middle of the screen thent the screen went black. Vizio person told me it was most likely the power supply. I then checked the internet and found power supplies listed up to $160.00. My question is are there any schematics or drawings or directions available that would help me to replace this sysem at home,
