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.
The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.

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.

Hello everyone.
I have a Hisense TV 40K321UW that has no led and does not turn on.
I have tested the power supply board
It has 12v at the 12v output when it's not connected to the motherboard. and it has 3.3v at the 12v output when it is connected to the motherboard. It has 0v at the 16v output.
The motherboard has 3.3v at some points, but not at the point marked 3.3v on the motherboard and also not at the eeprom (all pins of eeprom are at 0v)
I have attached image of some of the points where 3.3v was available.
