TCL 55" Roku TV, light on bottom flashes but no picture. Model 55S401 tv repair.

Step by step tv repair tutorial on a TCL 55s401 smart tv (Roku Version) with a backlight problem. In this video I'm going to show you how to fully disassemble this common television with a common backlight problem. The symptom is that when the TV is powered on, the white standby light at the bottom of the television flashes as though its about to come on, but absolutely no picture comes up. No picture flash or anything. Just a totally black screen. In most or all cases, its usually just one bad led on a backlight strip that causes this. So we are going to disassemble the television, find the 1 bad led, swap it out with a brand new led, and re-assemble the TV. Thus fixing the backlight failure, and repairing the television.
