Re: Vizio M3D421SR

on the vizio m3d421sr, the problems can start with the power U709-mosfet ic chip or u703-gate and D701-diod, if the voltage is correct for these then it is the command video chip, it has to be reworked and replaced from over heating. these TV's are not made for playing video games on, x-box will kill this video from over heating, the heatsink is too small for the load
