Where to get Backlights? Does the model matter?

@nullfox don’t search by the TV model number. You will have better luck If you search by the panel number. Remove the back cover from your TV and you should find a label that os glued to the metal back of the display. It’ll have the maker and model number. Use that to search. Of course if you already have the panel disassembled then use the numbers on the backlight strips. BTW

I would also like to see those black squares that you see. Squares are not typical of a failed backlight. Post a picture of what your display actually shows with your question Adding images to an existing question

Ok, uploaded the example.

@nullfox thank you and not quite what I envisioned. Yes, I would definitely replace the backlight strips as well :-)

I’m having issues taking off the plastic back casing. I got one whole edge unclipped but then there was too much resistance.

As far as I can tell the bottom bezel was the only part that has screws going into it, and the bottom of the back plastic casing has the pressure release clips.

It felt like the resistance I was feeling was a screw but I didn’t see a screw.

See if this helps also,. If not, See if a screw may be covered by a label or grommet. Or cap. Sorry I couldn't find a guide for your model also,. If there are crew inthe VESA mount remove them
