I have a Samsung qn65q8fnb. Overtime dark squares have on the screen. I’m having some difficulty figuring out what LED strips to get. When searching my model number I’ve seen backlight strips or backlight grid/arrays for every model except for my model. Is there a place I should be looking for the backlight at? or is it a “as long as its from the manufacturer it should be fine” situation? Edit: added photo

The model matters, yes, but what you really need to do is open it up and verify visually because even the same model tv may use different strips. Be extremely careful in handling the ribbon film connectors the attachment to the screen is delicate and easily damaged. Once you can see the strips I think you can simply search for the strips by screen size and and manufacturer then visually compare. You likely will find a samsung part number which should make it simple on the led strips themselves. It’s like ordering an lcd screen; you must identity the panel. Model may use several variants.

Hi @nullfox Check if there is a part number or type number printed on the LED strip itself and then search online using the number only to hopefully find suppliers. For example it might start with JL.E500K2330-?????-???-?-?? or similar
