UN46FH5003
|
The power supplys are compatible with the exception that the power supply current is b13 volts in the un46fh5003 model power supply It is a 12.8 v / 1.3a power supply and the un46eh5300 power supply goes to 13v/2.2a... I thought it would work to take a risk, but it is at each person's own risk... I took a risk and it worked perfectly... note: the voltage for the LEDs is the same because the kits are compatible.... | MIGUELTV | ||
