Just replaced 2 strips that were shorted open , tv plays great but has one light out in two other strips , will it play awhile like this. Doesn't affect picture much. Also I have this dark little spot shown in pic could it be trash behind the lcd on diffuser plastics.its right above the e in picture. My first led !

The Led is shorted, the whisker inside is shorting out from anode to cathode. It will work and last fine matey, but be sure to turn down the backlight to help stop others dropping.

I may not have used the right term but when I said shorted open I meant I replaced a strip that the whole strip died and was not lighting up. Any ideas if trash on white panel can show up on lcd.

does like like a piece of dirt between the diffuser plastics layers but hard to say and is it worth the risk of disassembly again.

Turn down the backlights as Reecey has already said.

The #1 cause of LED backlight failure is that they are turned up all the way. I run my backlights never higher than 75%. Never had any issues on any of the screens here.
