JohnnyDesaint: Great vid,I replaced the power board and the main board.every once in a while a blue light thats on the smaller.board thats on the left side turns on for a few seconds. .any suggestions??

Wiggy Lab: Thanks for the videos they are great. I have a Vizio E422VLE , The tv has no lights wont power on. I purchased a power supply board and installed it and still no power or lights. Before I purchase a main board, how can I check the main board to see if it is good. Can you tell me the voltage pinouts or other ways to check it ? Thanks. Main board 3642-1492-0150(4B).

cgull47: I have a vizio tv and whenever I press the power button the screen turns on for maybe a second and then powers down. I did all the obvious trouble shoots. I just replaced the power board with a brand new power board and it still has the same issue. Any ideas?

proto718: It smells like Teen Spirit. = )

CloudNineGirl: So so happy that you've learned good camera skills in your newer videos! Watching this one made me nauseous. :)

Doug Crane: yes I have a Vizio TV and you can be watching the TV I just left ghosters turn the power off and then you turn it on and then it turns back off or I could be watching it you have sound but then the sound goes away but if you rewind it and Playback me TV stations are watching the sound comes back what do you make of that?

Gary Stinten: just curious if the newer models support 240v as well.. want a newer 4k model and the don't seem to publish any information on whether or not they still allow this for newer models.

Teresa Sproles: Would this effect sound too? Mine was acting up for a couple weeks with no picture but sound at times. It would take multiple tries to get it to come on. Got up yesterday morning and nothing. Power light comes on but no picture and no sound. We have held the power button on tv to reset, unplugged power cord even over night, I disconnected the blue ray player and WII, I've held the mute button for 3 seconds, I've tried to the menu and it doesn't display. We've tried everything. Its not connected to a cable box either. I have a Vizio E500i-B1. Thanks!
