Hello. I have a Vizio TV model E550i-A0 that went off and is not turning back on. White light at corner responds when pushing power button and stays on for 2 seconds then blinks once and stays for another 2 sec and goes off and basically it continues doing that.
There is not backlight, no sound. Testing voltages on power supply I get:
1-2 :5v
3,4,5: gnd
6-7: 0v. Board indicates 12v but there is none.
8: 3.2v
9:0v
10:1.6v
11,12,13,14: 0v
Replaced the main board as they are well known for having eprom issues but I still have same exact problem.
At this point I would like to get your input on if you guys think I have a bad power supply board or a bad screen.
On the power supply/ led connector I get 0v on all pins
Thank you.
