TV's backlight no longer functions, LCD itself functions.
Hi all, I recently pulled a Vizio e320i-a0 out of my shed that I had left there as I believed it was no longer working. Currently, I am attempting to fix said TV. I’ve discovered that the display itself functions fine by performing the flashlight test, however I am not sure where to turn next. I have replaced both the main board and power board, but it doesn’t appear to have changed anything, I’m not sure what the most likely next culprit would be. I was thinking perhaps the t-con board could be the issue, but I’m frankly not sure. Anything helps!
ANSWERS:
"@zanglucarson since you already replaced the main and power board and since you can make out shapes etc. with a flashlight beam, the next step would be to check and most likely replace the backlight strips inside your panel. Vizio uses a hodge podge of parts for their TV’s do do a search based on the actual panel number. Remove the back cover from your TV snd you should find a label glued to the back of the panel with the manufacturing info. Use that data for your search. You can always add pictures to your question in case you need more info
