Sharp Aquos LC-40C32U Keeps shorting T-con

My personal tv, all of a sudden just got white screen with red blue and green vertical lines everywhere. Took apart found the t-con to have a short, new board was only $30 so just bought new t-con board, came in saturday, put it in this morning, powered up and worked great for about 5 minutes then the same thing again.

Have you checked the voltages on the secondary side of the PSU.. they could be over voltage? How do the caps look? Have you checked any fuses on the t-con board or any of the other components to see what blew.. ?

haven't check psu yet, not sure what is going, i know it's shorting out and making a loud buzzing sound the moment you turn it on from the t-con board.
