Good choice = you need surface mount FETs.

Thanks downunder; the SM Fets are part of the kit,Q706,Q707,but Q602,IC150 i think are also bad and  are in the kit.

Hi Guys;;i have good news; my Vizio E321VL is up and running,the following components were used to make the repair;F601,Q602 Mosfet KN8N60,IC150 STR W6053N, Q606,Q607 Mosfes KF5N50.
Note the replacement for the SM mosfet KF5N50 Q606,Q607 were T220 cases instead of the SM so i had to adapt them to the bottom of the board,see link. 

I think the Q602 Mosfet KN8N60, and IC150 STR W6053N,are good but since i had them out and had the New repair kit i went ahead and replaced those and kept the old ones for future repairs.Thanks for all your help on this,appreciate.

Glad to hear that you've resolved it, silva. Thanks for the feedback. I just worry a bit that there will be inadequate heat transfer from the fully insulated FETs.
