Vizio TV flashes blue with V logo briefly has picture no sound help

Hi i have Vizio EB00i-B1 and was working fine. Now when you turn it on the white light comes on for a few seconds the blue screen appears with the V logo and then goes blank. There is sound and if the room is dark enough you can see images on the screen. I tried holding power button for 30 seconds but thats all i have tried so far. I have some pictures of the boards but i don’t know which is which or what i might replace that may solve this problem. I also have another post on hear about a RCA 65”” that has similar problems but haven’t got any response to. Thanks.
