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?

Re: LG 55LB5600 LED voltage
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.Last edited by freakaftr8; 03-11-2018, 03:02 AM.Did I leave the soldering iron on?

"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.
