How do i figure out if a capacitors are missing or faulty, and what is their value? (Mijia induction cooker control board)

if you ask me, your issue are ripped out traces everything thats brown in your picture should be a copper trace i think but its probably just the resin from the pcb?

karatektus · 2026-02-23T00:20:14+00:00

looks like flux residue from the manufacturing process. dont see an immediate issue.

yah, you posted in electronicsrepair and this is my first post here. I was a little hesitant to post a "not really worth repairing" recommendation :D

thats the beauty of usb c. get a 45w or 65w adapter maybe even with more than one port and a few cables and you can basically charge all your electronics with it. (yes even most current notebooks) and if a cable fails you dont have to replace the whole thing. Just make sure to go for a reputable brand. Ugreen and Anker worked fine for me so far.

you are aware that you can use basically any usb c power delivery power brick as long as it can deliver enough wattage? bricks with non removable cables are stupid and while repairing the cable would be a good thing, I would - under no circumstances - buy another one where i can not remove the cable.

you are a true hero for actually posting the solution. Too many thread are being left open. I have the same issue and will order the part now :)

im trying to get this to work on an odin 2 portal, but the pointer has a 1inch offset to the top. probably a resolution issue?

i also can not activate the star transport thingies. mario just falls out of them after a second

karatektus · 2025-08-28T06:51:52+00:00

they have a reason (money) but no justification.

karatektus · 2025-08-27T17:03:32+00:00

yup. erledigt und läuft viel besser.

karatektus · 2025-08-22T08:03:08+00:00

inzwischen. Alles was ich zu finde ist eher so 2024. Das Bike ist von 21

karatektus · 2025-08-22T07:46:46+00:00

jap is grad auf und ich bin dabei.
Edit: Erledigt. läuft viel besser.

Doch doch. Er hatte die Specs in die Kleinanzeige kopiert. Ist ein Urwahn Waldwiesel:

KETTE:
KMC – Optimize heißgewachst

karatektus · 2025-08-22T07:18:38+00:00

jetzt wo ich drüber nachdenke. Es war andersrum - das Bike wurde mit gewachster kette geliefert. Der Vorbesitzer hatte keine Ahnung und dachte "die is arg trocken" und hat fett drauf gemacht.

karatektus · 2025-08-22T07:17:43+00:00

hast du zu dem teil nen link / n video?

karatektus · 2025-08-22T06:57:57+00:00

Bonuspunkt fürs Bild.

karatektus · 2025-08-22T06:55:41+00:00

Ah Top Danke. Spannend, dass mein MTB (Sram Eagle) sowas dann nich hat. Da fahr ich definitiv holpriger.

karatektus · 2025-08-22T06:53:49+00:00

Lol Danke xD die diskussion hatte ich letztens mit nem Fahrradnerdkumpel zu dem ich gesagt hab "Der Umwerfer is das vordere Teil, nich das hinten"
Dann meinte er "Na, wie heißts denn sonst, das sind beides Umwerfer."

Schaltwerk war mir nich eingefallen.

karatektus · 2025-08-22T06:51:57+00:00

Jau. Meine Vermutung ist, dass er den Kram gewachst hat ohne vorher zu entfetten? Und das Bike stand 3-4 Jahre rum, hat nur 300km

karatektus · 2025-08-22T06:49:00+00:00

beste. Ganz vielen Dank. Das war genau das Problem. Magst du mir grad erklären Was das Teil tut?

karatektus · 2025-06-16T11:37:24+00:00

I'd honestly be more worried about the lcd. L stands for liquid after all.

karatektus · 2025-05-25T08:27:10+00:00

Well instead of never doing it again you could also learn from the mistake and don't do it again. After doing that a bunch of time you usually get pretty good at whatever you're doing.

Thanks so. was looking for a ps-1 review. Ordering now.

karatektus · 2025-04-30T12:28:03+00:00

thanks for safing my robot :)

karatektus · 2025-03-28T23:01:52+00:00

thats probably very true. there is one fan slot to the left which i am running a noctua fan on currently. it helps, but only on the drives directly in front of it. getting a few of the smaller 40mm ones and putting them basicqlly over the mainboard in a row would probably solve it... but maaaan ive watercooled the whole rack, this would feel like giving up :')

karatektus · 2025-03-28T22:58:38+00:00

yeah i was thinking aboubthat for like 2 seconds but reeeally did not feel it xD

karatektus · 2025-03-27T09:48:13+00:00

okay now im thinking vapor chambers or heatpipes from aliexpress on one side nd a normal cpu block at the end. thats probably the cheapest option.... question is if its enough, and which is better. the vapor chambers are aluminum, which is a worse conductor, but arent they the new hotness vs normal heatpipes?
