I want to buy one of those SMD component books so I don't have to spend as much time searching my scrap boards for what I need, specifically ceramic caps and resistors as they seem to be what I spend most of my time replacing. But the only ones I can find are no name brands. Does manufacturer matter as much for SMD parts as it does with electrolytics or is the generic stuff likely to be fine?

If I replace SMD capacitors, they are usually in devices that are used a lot / always on. Therefore I replace them with brand name caps, since they came with them. Plus after the repair I don’t want it back and repair it again shortly after. Happened to me once.
I think it depends on what you are repairing. Most of the time I just end up stealing a small SMD cap from some junk board. Same with SMD resistors.

Hi,
I seem to have lost 2 resistors or capacitors while experimenting on the HP 850G6. Now nothing works anymore.
Can anyone tell me the position and values?
The ones I am looking for are on the BIOS chip. I have marked them in red in the picture.
Thank you very much

Hello
two small ceramic capacitors with values 040. Can you tell me
whether they are half short circuit or full short circuit?
Thank you -
Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:

Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)
1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.

Greetings everyone,
I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...
The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.
Upon closer inspection...
