Led Tv Backlight Strip Circuit Diagram. Led tv board schematic diagram. The lcd tv power provides a 12v output for the signal process board a 24v output for the backlight driving circuit and an additional 5v standby power output.
If we reference the chart above it appears that the current draw will drop from 120 ma per led to about 40 ma. Backlight leds are connected in series and parallel in the rgb led backlight modules. If you use the lcd led tv mainboard schematic diagram or circuit diagram then it will help you to trace the fault very easily.
If we reference the chart above it appears that the current draw will drop from 120 ma per led to about 40 ma.
Are you a technician. Intro to led strips. Will the leds still run at 2 75v. Figure 2 shows the block diagram of an lcd tv power supply with rgb led backlight design.
