TV Screen Black – Power Works – Nothing On Screen – Fix Sharp Aquos LC-50LB261U Backlight

The Problem: The screen on my 5 year old (conveniently out of warranty) Sharp Aquos LC-50LB261U LED TV won’t light up. After pressing the remote or the power button on the left side of the TV, the blue light comes on but the screen remains black.

“TV is getting power but it isn’t lighting up”

The Solution: While leaving the TV powered on, I pressed the menu button on the remote. I held a flash light up to the TV and I could barely see the menu in the middle of the screen but it was there.

Great news! A swap of the LED back lights inside the panel was worth a shot!

It was time to do a little internet research and source the replacement LED backlight specific to my TV model Sharp Aquos LC-50LB261U LED TV.

$53.48 ($44.99 + $8.49 Shipping) from Amazon was definitely more appealing than trashing an awesome Sharp Aquos TV. Also, I picked up some heavy duty screen suction cups ($8.89 w/ free shipping) to safely remove the LED screen. Better safe than sorry!

I was confident enough to open the panel and replace the LED back lights myself, but I found a tear down tutorial on Youtube just in case.

Followed the video, reassembled the TV, and it fired right up! Excited to see how long the new LED back lights will last. A big thanks to for the video.
