Is because of, BAD CAPS! Anyone else agree? It just seems like so many things go bad because of faulty capacitors or bad connections to the capacitors, or even bad design which doesn't include enough capacitors to filter the power.

bingo!
bad caps followed by bad solder joints.
cheap crap caps and zero quality control. -

Is it any wonder really?
Electrolytic caps are about the only part left that isn't truly solid state.

Re: It seems like to me the #1 reason for electronics failure...
I would vote for bad solder connections too, at least for usual, non IT related and non multilayer epoxy PCB using appliance.
E.g. most CRT TV and many other appliances do have some bad connections very early in their life.
For IT equipment with multilayer epoxy PCB`s, caps are probably the number one, as bad solder connections are very rare due to the generally higher production process.Comment

Howdy folks! I'm an artist in the video game industry, and my job entails making a lot of mechanical and sci fi assets. I thought it might be a good practice to start disassembling some electronics to be more familiar with how real electronics are manufactured and assembled, which is how i found my way to these forums.
When I started researching what tools I might need, I quickly encountered the warning "Some devices can maintain a potentially lethal charge in their capacitors, even up to years after last being powered on", which was enough of a scary thought for me to... -

Dears, this is my first post here and first try to fix my own laptop Apple MacBook Pro Retina 15-inch Mid 2015.
I have some general electronics troubleshooting experience and still as my hoppy but this is my first laptop trying to fix.
History: my laptop backlight stopped working without any reason.
Symptoms:
I have image on screen using my flashlight.
I have fully working laptop with the help of my external SAMSUNG LED tv via HDMI cable.
Keyboard backlight still working and can be adjusted normally.
Since two days I tried to follow all similar... -
I have a question since I am new here and I don't know if this is the right forum to ask these questions or if I am wasting your time.
I am 67 and have a lot of Radios and Electronics I grew up with which puts a lot of them at 50 years or older.
A lot of the capacitors are obviously bad but this is my problem.
An example would be the Panasonic RC-7469 Clock Radio and the Panasonic RF-888 Radio.
I have others like a Canon L-162 Nixie Desktop Calculator 110AC, etc.
I have the Service Manuals to some of these and other electronics I have and grew up with and... -
Good evening team,
I've been trying to learn electronics since the beggining of the year. My main goal is to fix broken consoles/laptops. It has been a very fullfilling journey and fortunately I've found my way around and I've already fixed a few of them.
While there's a lot of info online (this forum as an example) I would like to gather a few suggestions about books on electronics. I've already attempted to read a few ones, but to be honest I haven't found anyone that suits what I'm looking for. As an example "The Art of Electronics" is amazing, but there's...
