Guide · TVThe flashlight test tells you in one minute whether the panel is producing an image with no backlight. If you can see a faint image, the LED strips or LED driver are the likely fault; if not, look at T-con or main board.
Component test · TVLED strips are wired in series strings and run from a constant-current driver at high DC voltage (often around 80-200 V total). One dead LED opens the string and the driver shuts down. Test LEDs with a backlight tester, not a meter diode range, and replace all strips as a set.
Guide · TVOn direct-lit sets the strips sit behind the LCD and optical sheets. The job is mostly careful handling: lift the panel by its frame, keep the sheets in order, replace the whole strip set by part number and test before closing.
