What is this?
Hi guys, I found this on an old Ethernet adapter of an old p3 dead Mobo, they say tvr 07271, what is this? Diode? Cap? I don't know...

I mistakely pluged 100v japanese retro game console to 220v outlet.
So It seems that glass fuse and varistor have been blew up.
I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
Is there any way to identify varistor type in my sega saturn PSU?
Any reply would be appreciated.
EDIT:
It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage... -
Hello, I am looking for help to replace a damaged diode. The tristar was replaced and a diode was damaged in the process. I have a picture of the diode but dont have an exact donor. I mostly have macbooks for donors and only a few ipad and iphone boards. Diode part number: DSF01S30SCAP
Im not sure where to find the ipad board number. Anybody have an idea where else this diode is used on other boards? Thanks.... -
Hello everyone, I'm repairing an LG TV backlight and I noticed some strange behavior when I touching the backlight strip with a missing Zener diode.
So I replaced the leds on the strips and they seemingly working fine, but soon as I touch the strip which has a missing Zener diode the whole backlight turns off for a few seconds and then turns back on.
Is this caused by the missing diode? If so what kind of zener diode should I use to replace it?.
The led strips has 9 6V leds.

Hello everybody☺️ I am glad to be here and looking forward to a good discussion.
First of all, I am new here. Therefore I will shortly introduce myself.
I am Nico and currently I study Physics.
In my freetime I like to build and repair stuff. Especially big battery's.
A few years ago I got myself an electric unicycle, monowheel or however you call that.
The battery bms was broken so I replaced and resolder that. Nothing big.
I used this thing for some years and had a lot of fun. Unfortunately I used it last time in heavy rain. Usually everything... -
Hello Everyone,
I have 1 diode on a circuit that I suspected to be faulty because the forward and reverse bias has a voltage drop reading.
While compared to the reading of another diode from the next channel it won't read at reverse bias.
Now the problem is; it does not have any body marking.
So I tried to sketch the diagram and found out that it is connected to the base and collector of the C3632 transistor.
What do you think is this diode?
Can you please suggest what part number can i use to replace this faulty diode instead?
Hoping that you...
