CA-288 Universal 26-55 inch LED LCD TV Backlight Driver Board TV Booster Constant Current Module High Voltage Board

Feature Uses for 26 inch 55 inch LED TV display voltage exceeds 100V and above 165VInput voltage range 19 45V DCOutput voltage range 60 165V DCOutput current 10MA 1000MA can be setNote The operating voltage of the light bar must be any voltage between 60V and 165 Cant be lower than 60V Can not be higher than 165V the design working limit voltage condition of this product shall not be higher than 165V If this voltage is exceeded the screen may be dark or the lamp may flicker This product only has constant current no constant voltage and the voltage will be automatically adjusted to the corresponding voltage according to the required voltage of the light bar so you do not need to entangle the voltage measured at no load Correctly illuminate problems that may be encountered 1 The brightness is not enough the screen is obviously darker than the original board there may be two reasons First after connecting the dimming foot try to adjust the brightness with the remote control If it cant be solved test the voltage of the actual pin Note the brightness is the highest when the product is 0V and the brightness is the darkest when the voltage is high If the voltage range of the analog voltage mode is between 0V 5V or 0V 3 3V this should be adjusted if the voltage is always at a high voltage and cannot be reduced If it is a PWM signal the voltage is stable at 3 3V At this time if the light is adjusted to the brightest or the requirement is not met the
