I have a section of the back light that is apparently burnt out.


Are the LEDs themselves replaceable? Has anyone pulled one of the panels apart before? I have yet to really pull it apart much but am going to dive in this weekend.
 
I haven't disassembled the panel itself but there are 6 (+/-) connections going from the pcb to the LEDs in the panel
That suggests they're using 6 separate LED stripes

The LEDs itself aren't necessarily "burnt-out" either
I'd try feeding then low amounts of voltage first (don't know what they need exactly)
And make sure to use resistors
 
I will check it out. Would be nice if I could figure out whats going on.
