Found a 32" Vizio that wouldn't even show standby light. I opened it up and checked 5VSB, which read 0. After looking around on the power supply for a few minutes, I noticed a huge black spot by an IC. Pulled the heat sink off to find this:
And the back of this part of the board, for good measure:
I believe the full part number for that IC is ICE3B1565J.
R912, R913 both reading 100Ω. ZD903 and ZD904 both show continuity both ways. Seems there's a cap missing at C959, but I can't confirm. Edit: Same cap missing on same board from ShopJimmy.
Is there anything else I should check before ordering that resistor and IC? Also, regarding that IC, would it be prudent to add a better heat sink than this thing it came with?
Thanks!
Edit: After some thought, I figured this would be better suited for the PS forum. If so, could a mod please move?
