he brightness is not enough, the screen is significantly darker than the originals .

now you need to do the two things :

First, attempt to use the remote control after connected to the transfer barefoot

to try brightness, if not resolved,test the actual pin voltage (Note: it will be the

greatest brightness in 0V, the brightness will be the darkest in greatest Voltage) .

if it is an analog voltage mode voltage range is between 0V-5V or 0V-3.3V,

if the voltage has been in hight condition all the time andcan not be reduced ,

now you need to adjust it . the voltage is 3.3V if it is PWM signal ,

it still can be up to request if adjust to

the greatest brightness at this time ,you need to do second program

Second, adjusting the resistance , increases the current to meet the requirements.
