Philips 49pus7272/12 backlight issue
I have a pretty old philips 49pus7272/12. One day, the picture just went dark (still have sound and ambient light). When I shine a flashlight at it from an angle, I can make out shapes, so it seems to be an issue with the backlight.
How would I go about fixing or replacing it?
I opened up the back cover and there seems to be 4 panels, but I have no idea which is which or what to check.

UPDATE:
So I took the screen apart to look at the LEDs.
There are 7 rows of 12 each (6 on both sides).
On one side, Only 1 out of 7 worked.
On the other side 6 out of 7 worked.
Do I need to switch out them all or would just the broken ones do?

see if you are able to get the led strips for replacement as it is faster.
if you tested with multimeter and certain LED has failed, well, it can be desoldered and replaced with a working same specs LED.
it take times, e.g. removing the LED lens to expose the LED, desoldering, assembling back, resoldering the LED, test and re assemble the LED lens.
