Not sure where to post this but I need some help fining info or the actual part number for a diode I found to be bad. I'm working on an arcade monitor chassis and the board is a JW-RODO-888A and I found a bad diode in this cluster of 4 but I would like to replace all 4 and the only numbers on it are 20D then under that is a "4" then under that is "3B" I can't find anything and even went on live help at digikey. Any help is appreciated!

Re: Diode help needed
It's an odd one I have never run into before there is a sticker on the tube that says Pentranic and A89PNT30XComment

Re: Diode help needed
circle them on the pic.
4 in a group near the ac input are just common diodes.i would use 1n5408 as i stock those.
thats a 3a 1kv gp.
replace all 4.
a89 crt is 35"!
thats a bigassed video game!Comment

I sent IPAD 7 WIFI-2019, model A2197 to a techincal service, but they did not repair it, so i am trying to fix it. The problem is the IPAD is not booting and no turn on.
This is what i found until this moment:
1) with battery connected, the current draw from the power supply is about 450mA from the charging port.
2) no short circuit in lines VCC_MAIN, VCC_BATT.
3) with the power supply, or with the battery, the 3.7V of VCC_MAIN and 1V8_ALWAYS are generated without problem.
4) the current draw from the power supply, without battery, is about 26mA from the charging... -
I'm thinking of buying some single smd led diode for tv repair to have under hand there is so many, 2835 k-6000k 9v.6v, 3v white etc but don't know which to have if you advise me which Should I buy and which is most usual and bäst to have under hand. thank you -
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...
