Is it practical to repair this monitor (Philips 436M6VBPAB)?

[Legion]

I have a Philips 436M6VBPAB. The diffusers that sit over top of the LED backlights are falling off. I can hear them rattling around in the chassis. Wherever they have fallen off I have bright plumes on screen. I've never taken apart a monitor before and I'm wondering if it's worth attempting the repair. My main concern is whether or not I'll have to peel apart adhered layers to get at the diffusers/backlight.

Just wondering if anyone has attempted a repair like this on a monitor before and what I would have in store for myself if I attempted it?

Its an edge backlight monitor. You will probably have an LED strip on the bottom, and there will be a bunch of lens on them, connecting it to the diffuser layer. I dont think you will need to peel off anything to fix it. Basically the panel likely can stay in one piece.

Besides, what do you have to loose, other than your time?

You have nothing to lose -  Don't turn it on, take it apart!

I don't have a backup monitor, so I have to be careful.

I'm also not sure it's edge lit, I have blooms across my screen at a spacing that suggests 5 rows by 5 columns.

The Philips Momentum 436M6VBPAB has a local dimming feature, but it's bad. It's edge-lit from top and bottom and has a limited number of dimming zones. When a bright object moves quickly across the screen, the local dimming zones aren't able to keep up, causing a glowing trail behind it. The local dimming feature is only available in HDR and, unfortunately, it can't be disabled.

Yeah, I saw that too, but what I'm seeing on my screen suggests otherwise unless the diffuser is able to take edge LEDs and focus their light at arbitrary points in the middle of the screen.

Yes, that is possible. Usually done in the diffuser plates. They are a sort of 2D light pipes.
