Vizio E420-A0 fails to sustain power
TV will shutdown eventually on its own - longest "session" was longer than half a minute. In some instances, the TV never generates a backlighted Vizio logo and its power LED immediately starts to fade after going full bright white.
ANSWERS:
"Based on the description of your TV issue, I suggest replacing the EEPROM on the main board. When this IC reaches a high temperature its very likely to cause strange behaviors.
Also, the EEPROM is cost effective and it only requires of an average soldering skills.
Good luck with your Tv RepairJourney
