sharp aquos lc-60le640u Backlight

[Shinson74]

I recently came across this Sharp AQUOS. It appears that there is a backlight issue (see picture). Any advice on going about repairing this?

Possibly top and bottom edge lit and some of the bottom leds have failed.

That’s my thoughts. I have LEDs from a Sharp 70” that work. Just have to figure out how to go about replacing them.

The led "strips" are at the bottom and are different between the 60" & 70". The 60" uses two, bottom left & right, and the 70" uses three bottom left, middle, right.

What ever you do, make sure the LED strips are made for your LCD panel model number.

Was it replacing individual leds that you are referring to?

I wish that I could replace individual LEDs, but I was referring to the strips.

Are the strips the same length? Whereas the 60 has 2, and 70 has 3. Could I rewire ones from the 70”?

No, the 3, 70" strips together are longer, then the 2, 60" strips. they go from one side to the other of the lcd panel and very likely light the edge of the light guide plate.

So today I turned on the tv and the spot is gone. Now what?

Turn the backlights down to increase the lifespan of the leds. It may have been one of the led connections has a poor contact rather than a led gone. Time will tell.
