Just thought I'd share this you.
I've just dismantled an LCD panel out of a 46 inch Sony TV, in this particular case the LCD is a Sharp model.
Interestingly it's edge lit top and bottom, with two modules on the top, and two on the bottom, each containing 47 LED's in series. The modules are connected in pairs in series as well, so it uses two series chains of 94 LED's - and four wires are brought accordingly, actually split left and right rather than top and bottom.
I've just measured the voltage drop across a single LED, and it's 2.7V fed from 12V via a 390 ohm resistor - s0 that makes just over 250V for the entire series chain of 94.
So what to do with them now?
