Excellent video. Looks easy enough I might give it a try

A tip for when peeling off the backlight strips. Mine were bonded really well to the case and it took quite a bit of effort to peel them off with a dinner knife slid underneath. The first strip came off suddenly as I got near the PCB that connects the two strips and I ripped off the narrow piece of PCB that slots into the connector on the backlight. So be careful as you get near the end.

Hi whats the part number or where can i get the rear led strips from?

Where could I get hold of these LCD strips?

The colours are the wrong way around on the cable to the LED connector. So red goes to the negative of the LED strips. My 32l3863DB model has the same mistake in the wiring colours as your TV. (If they intended red to be positive). Anyway, thanks for the video, it was really helpful. Two questions, is it ok to clean the outer diffuser sheet with IPA and is there any need to worry about any dust or fluff that may have accumulated on the sheet? Or would that even be seen when the backlight is on? My sheets will be sitting for a few weeks until I get backlights.

cheers man, that's very useful. One question, please: i have one exactly the same. where is the power cable for LEDs? how can i test this?
