Re: Vizio P-Series 4K tv with temporary sound and no picture P652ui-B2

yeah so.. I had this same exact issue. I ended up replacing all four boards (PSU, Mainboard, LED Driver and Tcon and still no luck. I was furious and threw that mf'in mainboard in the oven at 380 for 10 min and then cooled it, installed it and the damn thing worked. Incredible.
