This TV turns on and has a blank black screen with no picture or sound. The backlights work fine. The unit will not turn off by the same power button that turns it on.
I did some research as there is loads of info about Vizio's here. I'm new to these damn LDO (1117) regulators.
I copied and pasted this from PlainBill's help with a different TV with the same regulators.
My voltages for these regulators were:
U2 2.0 3.3 5.1
u7 0.0 0.9 1.9
u8 2.0 3.3 5.1
u33 1.2 2.0 5.1
Should I come to the conclusion that u7 and u33 are shot since the input voltages seem ok? I just need a confirmation.
