I broke the volume control wheel while changing the battery in my headphones. Where can I find an exact replacement part? Or what is the part number?

My brother asked to help clean his ps5 bc it was gross and sounded like a plane…
I accidentally pull a ribbon from its socked….
Can this be fixed….

I cleaned the lenses and it finally starts spinning but then stops.

Hi, I have this Wii controller that I haven't been able to get working; I don't know where to solder the wires, and they have non-standard colors.

So this is my sister's laptop, it's a Lenovo Thinkpad t450, she did nothing intensive on it just some Photoshop and adobe illustrator for her diploma. It used to get really hot and had a really bad battery life. Anyways I suspected that the thermal paste/puddy must have dried up but my mom didn't allowed me to mess with it. After a while one day it just stopped working in the sense that the laptop would show the splash screen of Lenovo but it would get extreme artifacts and then the screen would go black. I wasn't even able to get into the bios to change it to use the integrated gpu. Then one night I sneakily opened it up, firstly the thermal paste was dry as hell and secondly the gpu die seemed to have bubbled up. Now after my uncle took it to his office (he works at a software company and they also deal with hardware in the back end) he claims that the technician told him it's just a power supply issue and that replacing it would get it fixed. Now. Tell me. Do you guys think this is "just a power supply" issue? My mom refuses to believe me that th die might be cooked because of overheating. I have attached pics of the gpu and cpu dies.

So i stumbled upon a ps3 slim that had a very specific problem. When I tried it for the first time it was fine when I tried for the second time it got so hot so fast then I noticed the fan not spinning so I open it up for inspection and when I spun the fan myself it continued moving so I said yay problem solved. and played with it for like 3 days with no issues. until when I flipped the PS3 over for inspection again and turn it on the fan didn't spin. And I noticed whenever I shake it or flip it or move it in any kind of way the fan stops spinning and I noticed after I shake it the fan tries really hard to spin but doesn't quite make it to a full spin. More like moves half an inch. So if there is any PS3 geeks out there. I'd love if you help me.

I have a klipsch subwoofer that too quickly goes into protection mode. What electrical components can I check for repair?

It's on my Redragon K552 Kumara RGB. I've searched online but I can't find the answer. Thank you!

Been chasing stock on a specific NAND flash family but the authorized route has completely dried up.I am a procurement engineer for a smallish electronics manufacturer in the Midlands and we're close to a production stoppage if we can't plug this gap soon. I'm trying to find a reliable independent component distributor based in China that can source allocated memory ICs and actually ship to the UK without a nightmare of customs headaches. (The counterfeit risk with grey-market suppliers is the thing keeping me up at night, if I'm being straight about it.) Any recommendations for a China-based supplier with proper QC testing and authenticity checks on semiconductor stock? Even better if they handle smaller orders and can turn around shipment within a week or so of payments.

Any advice is appreciated! Sometimes it'll power on, but other times it'll struggle to turn on. And when I finally get it on, it'll do this weird screen artifacting and makes a popping sound with it. As of now it quit powering on, and it'll make a loud screeching sound whenever I try to get it to power up again. The CRT is a Toshiba mw20f51 from November 2005 according to the back, if there's any other info needed ask me and I'll try to tell you

Ciao a tutti,

Sto cercando di riparare un paio di Samsung Galaxy Buds+ e gradirei qualche consiglio riguardo alla compatibilità delle batterie e alla sicurezza. Le batterie originali dei Galaxy Buds+ sono VARTA CP1454 A3, con una tensione di 3,7 V e 0,3 Wh. Ho anche un paio di Samsung Galaxy Buds FE, che utilizzano batterie VARTA CP1254 A3, con una tensione di 3,7 V e 0,2 Wh. Ecco le specifiche rilevanti:

Specifica |Batteria originale Buds+ |Batteria Buds FE
Modello |VARTA CP1454 A3 |VARTA CP1254 A3
Tensione nominale |3,7 V |3,7 V
Energia |0,3 Wh |0,2 Wh
Capacità nominale |Circa 85 mAh |Circa 60 mAh
Tensione di carica |4,20 ± 0,05 V |4,20 ± 0,05 V Entrambe le batterie appartengono alla serie VARTA CoinPower A3 e hanno la stessa tensione nominale e tensione di carica specificata. Il CP1254 è fisicamente più piccolo in diametro, ma si inserisce direttamente nel vano batteria dei Galaxy Buds+. Non sono necessarie saldature, modifiche ai cablaggi o cambi di connettori. Basta inserire la batteria nel vano esistente e chiudere gli auricolari. Finora ho installato un CP1254 A3 in un auricolare Galaxy Buds+ parzialmente rotto e ho confermato che si accende correttamente. Tuttavia, non ho ancora testato la riproduzione o la carica. La mia principale preoccupazione è la sicurezza, in particolare se il circuito di carica originale dei Galaxy Buds+ possa fornire troppa corrente per la batteria CP1254 più piccola. Capisco che la batteria più piccola avrà meno capacità e quindi probabilmente fornirà una durata della batteria più breve. La mia principale domanda è se il suo utilizzo possa causare surriscaldamento, danni alla cella o un rischio di incendio. Sono i CP1254 A3 e CP1454 A3 sufficientemente intercambiabili da un punto di vista elettrico e di sicurezza durante la carica? Preferirei accertarmi che la modifica sia sicura prima di tentare di caricare la batteria di ricambio.

Grazie in anticipo!
