Led strip repair kit with tools https://bigdogelectronics.net/collections/for-techs/products/television-led-backlight-strip-repair-kit-includes-50pcs-3v-1w-350ma-2538-led-s Here is a Vizio e420-a0 led tv with intermintent backlights. The usual symptom is sound with no picture, just a black screen. This television uses a total of 5 backlight strips separated between 2 lines. One line powers up 3 led strips and the other line powers up the remaining 2 led backlight strips. This is a step by step procedure on disassembling and reassembling the tv, and also how to check both lines using an led tester or just using you dmm voltmeter. Finally finding the bad led and replacing the single led that caused the whole problem with no backlights, no display, and no picture.
