Re: Vizio VW37 Power Supply PSON working but no 12v or 24v output

I received a Vizio with the same problem. After digging around with suggested voltage checks, I found that U33 was defective. These were the symptoms:

Standby VIZIO Logo on : 5 Volts enable
No Power with Remote
Turns On with Side button Power, Backlight is on
No video or no reception (No Signal is not present)

Voltages were present, 5V, 12V and 24V. After I replaced the U33 before the TV works Ok. Now is back with the same problem so I decided to do the same. Unfortunately...
