Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off.

Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.
It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.

hello! hope you are all well. i have a macbook pro a1425 and it won't turn on. i took it to the service center and they said it's fine, it turned on 2 times and then it wouldn't turn on. on the power supply there is a yellow dot that is charging and turns green when charging but when i turn it on it doesn't turn on. i opened it and saw on the motherboard that 2 elements are missing, i am attaching the photos for you to understand better.
thank you all -
I have another tv to fix for my friend. It is a Hisense smart tv. After turning on, it will freeze or stuck on certain screens. However, when it is connected to a tv box, it will automatically connected to it and play without any problem. I wanted to go to the menu and reset the tv. But it just freezes before I reach the reset menu. I have tried the hard reset methods, but no luck. I guess the main board is with problem. Will reflowing one of the chip may fix the problem? If yes, which chip should I try reflowing?
The followings are some videos showing how it freezes.
