Hello,
I have a Lenovo Ideapad 3-15ALC6 computer that I'm trying to repair.
Initially, the computer wouldn't start, and there was no power consumption from the charger. The board itself is reference HS261&HS561&HS761 NM-D521 rev 3.0, where you can find the schematic and board view here: https://www.badcaps.net/forum/troubl...-hs761-nm-d521

When I opened it, I noticed three burnt components near...

No, the LEDs are like new, none have ever heated up to cause the diffuser to burn (see my photos)

Hello.
I'm sharing with those in the know a problem I'm having with my Samsung UE55JS9000T TV, which has a backlight fault with halos of light on the sides (see my photos). This is a model with LED strip backlighting on the sides.
I took the TV apart to remove the panel and noticed that the "yellowish" film on the Plexiglas light diffusion plate was stuck to the LEDs. When I peeled it off, it left marks on the Plexiglas plate, which I cleaned as best I could with rubbing alcohol (see photo).
The result isn't perfect, but it still seems pretty good to me.
