just a quick question do all qled leds appear blue when fault finding ?

[jimbofz]

i have replaced many leds strips that have changed blue when they are worn
and the new replacements are perfect white
but when fault finding do quantum leds always look blue?

QLEDS are blue then filtered, the leds you are use to are blue to start then they are coated with phosphor to emit white, this phosphor burns off over time or when poorly implicated and the blue light shows through which means they need replaced. So blue is normal for Qleds.

NO, Qled lights are blue that's normal, they get filtered differently than the older style led tvs. Meaning they do not get coated with the phosphor that makes the older style appear white.

Seemed like you were having trouble grasping the concept, heres a teardown, this Qled tv has a yellow sheet that does the job the yellow phosphor does in the non-Qled tvs: https://www.youtube.com/watch?v=YYICw1dkpaA
