I use https://log.repairdats.com/ (MantisBT) to note down everything that falls on my hands, so I keep track of what usually fails in every console/etc.
- Project: Company (Sony, Nintendo...).
- Category: Console/etc related (PS, Famicom...).
- Type: What is it (Console, Add-on, Accessory...).
- Region: Doesn't always apply, but I use it anyway (NTSC-J, NTSC-U/C, PAL...).
- Queued: Waiting on the self to be repaired.
- No components: I'm waiting for needed supplies to arrive.
- Repaired: Came back to life.
- For parts: Can't repair that mess, so I'll use it for parts.
- Working: It just worked, no repair needed more than basic maintenance.
- aesthetic: Things like broken plastic pieces, scratches...
- audio: Audio not working properly.
- boot: Power works but doesn't boot properly (either to typical blank screen or to its BIOS).
- game: It boots up correctly, but doesn't boot games.
- mechanical: Things like buttons not working.
- power: No power at all.
- video: Video not working properly.
- working: Everything works (goes along with Working Status/Resolution).
