CA-288 Driver 26-55inch LED LCD TV Constant Current Inverter Board Universal Backlight Module DC 19-45V to 60V-165V Boost Module
Specification:
100V the above 165V the following
Input voltage range: 19-45V
DC Output voltage range: 60-165V DC
Output current:10MA- 1000MA Can be set
Purposes: for 26 Inch-55 Inchled TV monitor voltage is exceeded
Increase current method:
Use a soldering iron to solder a certain solder joint pointed by the arrow to increase the current (brightness)
Possible problems with correct lighting:
1. The brightness is not enough, and the screen is obviously darker than the original board. At this time, we start from two aspects and connect the dimming.
After the feet, try to use the remote control to brighten the brightness and see if it can be solved. If it can't be solved, test it.
Lower the actual pin voltage, (Note: My product has the highest brightness at 0V, and the darkest brightness when the voltage is high)
If it is analog voltage mode, the voltage range is between 0V-5V or 0V-3.3V, if the voltage
It is always at high voltage that cannot be lowered and this should be adjusted. If it is a PWM signal, the
The voltage is stable or 3.3V. At this time, if it is adjusted to the brightest and still cannot meet the requirements, the first step must be implemented.
Two options. Second, adjust the resistance on the board and increase the current to meet the requirements.
Note:
1.Due to the light and screen difference, the item's color may be slightly different from the pictures.
2.Please allow 1-3cm differences due to manual measurement.
Package includes:
