VIZIO E550VL No backlight!
Hi everyone!
My dads E550VLs screen used to occassionally go black, then come right back on. After about a month of it randomly doing that it finally went out completely. Sometimes you could turn it off and on and it'd come back on, but usually for only 30 minutes or so. I did the flashlight trick, and you can see the screen as well as toggle through menus. I also checked for sound via xbox. It appears to work perfectly minus no backlight. The next thing I did was take voltage readings with the tv on and everything still connected. I checked all the connectors on the power supply...
