Hi all, I'm working on a Hisense 50H6E that blew a LED. Knowing nothing except how to solder on a new LED we ordered from amazon a package of:
"SMD 0.5W 2835 LED"
v(f): 3v - 3.2v
i(F): 150mA
These LEDs looked like the same size, so i went for it and it worked for about 5-10 seconds, got the tv splash screen and then it bzzt the picture went out.
Did I just order the wrong junk SMD LED? Reading up around here I see there are definitely different types of LEDs, and ratings.
EDIT: just now looking at the power board again I see 160v/400mA in the output specs. Is this my backlight voltages and led spec? so 160/36 total LEDs=4.4v? should I look for 4.4v 400mA LEDs?
Or should I be looking at the power board?
Should I solder on another, and get a reading from the LED output on the powersupply board before it fizzles out again?
Thanks from Idaho!
