Hey /diy/. What are the most common reasons that cause electronics

Could your question be anymore broad?

Reason 1: Tin whiskers

https://nepp.nasa.gov/WHISKER/background/

Repair: Smack affected device.

Reason 2: Bad or old, dried out Caps

Repair: Replace them with new ones.

What's with all the bingo tier threads lately?

perhaps the person you have hired is unable to make a good service or demencionar your needs

Power surges and shit capacitors

1. Dried out caps
2. Poor power filtering
3. Misuse (overloading, covering air vents, moisture exposure )
4. Thermal load (cooling effected by dust)
5. Shit design / cheap components
6. Low tolerance components
7. Poor assembly
8. Mechanical wear (switches, relays )

Likely hood of kill scenarios are cascading failures

>>1075576
reason #1 (arguably the only reason actually) is heat.

The three c's
Comm
Connecters
Current

Dust.

Get a fucking ESD vacuum.

>>1075576
Dry solder joints, water damage, cheap components crapping out, voltage spikes burning out a part, prolonged exposure to a hostile environment (hot, cold, damp), impact/vibration, wear and tear, dirt/dust ingress, and don't forget good old user error.

There are a bunch more but I'm tired and need to sleep.

this is actually how my last computer died. it was rock solid until i turned on my computer while a cockroach was in the power supply fan. it sprayed roach guts all over the inside.

I find that if its not busted caps its usually a broken PCB trail, usually from corrosion.

Same thing that plagues software.

Fuckin contractors and installation/repair techs opening splice cases they aren't supposed to be in and fucking with my perfect goddamn MS2 splices.

Reeeeeeeeeeee

Some things basically never fail. Digital electronics will last forever.

It's almost always the power electronics or mechanical failures.

Temperature related or liquid damage, doesn't even have to spill damage if the environment is humid and cold like the UK.
