Good day I have a LG led TV model 32LB551A with saturation of brightness in central led strip medium voltage of the source and it marks me 68 volts towards exit of strips leds is normal? thank you attached reference photo because in mine you see is the central strip that way

hello my partner, those white spots that appear on the screen is a problem of loose reflectors, try to disassemble the panel very carefully, and when you place the reflectors try to place them well, because otherwise the light can lose the way my dear little fellow, take that detail greets you the Caribbean marshmallow the sweet myself I am

Effectively the fault was that the diffusers of the LEDs had been detached, thanks
