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

Hi everyone,
help me please
I have an HL-DT-ST BD-RE GGW-H20N with ROM version: XA02.
When I tried to burn a 25GB Blu-ray disc using ImgBurn, I got an error.
I will share all the details with you, including the disc information.

I will just preface all this by saying that I have a fairly technical background but have never attempted SMD electronics diagnostics and repair before, I really like the idea and want to learn.
I have a MacBook Pro late 2016 that died maybe four years ago. Over the course of 30 seconds, it got slower and stuttered, until it froze for a second and died. No click from the trackpad anymore, nothing. I started getting interested in electronics repair and decided to give it a shot, so I opened it, removed the battery (one cell was puffy), took out the motherboard and experimented with...10-15-2025, 01:53 AM -
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... -
Hi all, I hope this is the right place to post.
I'm having a problem with a Dell 9310 which is posting 2 orange, 4 white lights on startup (hangs on Dell BIOS logo). The service manual says its a RAM failure.
I've taken the motherboard out and noticed that one of what looks like an SMA 0805 resistor has blown (see photo). The board is an LA-J144P Rev 2.0(A01).
1] Could someone confirm what the component that has blow actually is (and where I could get another from).
2] Whether this component is likely to cause the RAM failure issue, and if replacing... -
