LG 55LB5600 LED voltage

[freakaftr8]

So I got this TV in with a flashing back light immediately took the TV in disassembled it down to the backlighting system. Found 5 burned out in various places. These appear to be a 5 V LED with a bucket style diffuser lens. Unfortunately I do not have any of these in 5v. Anyone have any ideas where to find these single LEDS?

Some more pics. Oddly the LED is about the same size as the 3v ones LG makes.

Sorry I meant 6v, not 5v. These appear to be 6v. Can I just the in 2 3v piggyback? I know this is dumb but it's for someone who lost everything and just needs a tv not caring on bright spots on the screen.

"Can I just the in 2 3v piggyback? "
??? You want to put 3v ones and ruin a giant 55inches? It's out of logic.
LG produces tv with 2 types of 6v leds, you better search the web shops for your precise model, if there is a sheet of led data then you start from there to search on the various web markets, i found mines on aliexpress.
