vizio previous power problem would not power up. fixed that now I have blank screen Video Clips. Duration : 0.32 Mins.

this is a vizio vp322 my power board has went out a few capacitors popped, replaced board and this is what i am getting. the only responses i get is the power button. on the remote and side buttons. it powers on and off with no problems. i can only turn it off and on. the screen lights up but blank picture nor any sound. after further inspecting it was the main board. I must have bought a defect replacement that has the same problem. tv fixed
