Re: LED TV dummy load.

Sorry to revive an old thread, but I just wanted to ask.

I know i can calculate led resistance knowing the loaded voltage, and current.
i.e if i the power board outputs 200v 250 mA to the leds
I could use ohms law:
R= V/I 800 ohms. W = i*i*v 12.5W. An replace leds with a 800 ohm 12.5 W resistor
But if i lower those 200v (250 mA) to 20 v 2.5 A
can i connect that output to an electronic load, and start at minimal values until the led backlight is on its working condition range?
Don't know if i'm shooting a mosquito...

hi all from buenos aires, i found the site trying to fix a lcd power board.
