Backlight Out but can see picture with flashlight Vizio E320-B2
When turned on the Vizio logo comes up dim and flickering and then appears to turn off. The picture can still be seen with a flashlight on the screen. Sound is fine. Based on what I’ve read it is most likely the power supply or the backlight but I’m not sure how to test or what parts to order. Included below are pictures of the boards.
I have a multimeter but not sure what I should be testing. Any help is greatly appreciated!
