Diode? Hence the arrow-line symbol?

Yeah - I know.
I kinda freaked out & rationality went out of the window.
I got a test replacement in just now.. so will reinstall the fly tomorrow & share the result.

Can you confirm that is a 5.6V 200mA schottky or something else?

Hello yes hi I accidentally dropped my Switch through a wood chipper plz revive it

I'd still try to harvest chips\components from it

Lol, like clients are ever that honest anyway XD

Southern Cali clients be like:
*Drops bag on counter* "Fix it."

True story actually, I was 'elbow deep' into a solder job and a customer did ^that w\ a controller. I will never work a front counter again XD

@floxcap @Gosnik I put the "?" marks cause I was honestly unsure. I see now it could've been read dick-ish.

I have a Lite board I can check. Besides trying to see the marks under a scope, is there a way to identify what it is?

Getting off topic but I'll show ya how i killed the slims....

Compared to my oled XD

I don't think that its off topic, many think that this here is an easy installation, but its not, without the right tools and skills you are fu**ed ^^.

I live on the edge... of forum XD

End of world scenario and this is the last PS2 Slim on earth: pull the IC, remove broken legs and try to 'retrace' the legs to the board.

That OLED was a success, correct?

 

[Dee87]

My first post-APU grinding Switch OLED. Works like a charm, and glitches in less than a second. boots into hekate.
I used the shield as GND. Won't be touching anything in the APU other than the two caps. Lesson roughly learned.

Bro u can still touch it there no problem as long as u dont grind on it everything is fine Xd

but congrats

@QuiTim I just noticed that RP2040-Tiny is selling on aliexpress again. Did Waveshare fix the resistor problem already?

 

[Flaviocarvalho]

One thing is right....just reading this forum i learned a lot about eletronics and other stuff...thanks to everybody.. my first microsolder i fucked a switch...now i did a reball and it worked kkk

Yep, i guess they did. Just ordered 3pcs but it will take some time until they arrive.
In the meantime our friend @Kiuxn in this post is already having fun with them https://gbatemp.net/threads/picofly-a-hwfly-switch-modchip.622701/post-10171423

@FreeLander did you grind because you saw a 'Tuber do it?

I just watched Northridge Fix grind a smart vacuum board to expose traces and turned the video off. Great, now we've got NF showing people 'look, grinding ez' and TronixFix paying too much for broken systems thus driving up market prices (among other cringe, the PERFECT amount...).

I Think - what's been pointed out to me - that it is probably a diode.

I've done quite a bit of searching and haven't found any direct information on it yet.
There seems to be a few places around that are selling "switch lite diode".

I suspect though that it might be a schottky diode of some value - hopefully that means that the value doesn't matter too much - so I don't have one on hand that will fit - but I'm going to test my theory (hopefully) tonight with an ugly hack:
(Schottky 2A 30V 380pF - is all I have on hand).View attachment 374682

I took mine off because I thought I saw a bridge from the nearby cap and it literally slid off my multi-meter probe. So I'm replacing this now but I'm not sure what it is exactly. 8A!? Fuse maybe!? Either way, taking it off and booting up now has a black screen oppose to a blue screen. Who knows might be the culprit because blue screen is, in my experience, to do with shorts (amongst other problems). Going to find this component (that was probably damaged) and then check. If normal boot works again then that LITE ground point (on the cap) is too risky (for me anyways) and will just reinstall RP2040 with a new ground point (like on top of USB-C charging point or something). Any clues as to what this component is anyone!?

Why not just mask off areas you don't want solder on?

I always mask all my points once I check the values in continuity mode but whats the difference in the beep from the dmm of a short or ground!? And just looking back at my photos, i did use a blob on that Cap. Maybe the diode/fuse next to it is more sensitive than I thought.

No no, I put that kapton tape down before soldering, THEN solder, and removed the kapton tape.

but congrats

Thanks but it's tough getting solder into that point, and psychologically I just don't want to touch it anymore. this is how I do it now and it works great. Thanks

Here's what mine looks like:

Doubt it'll help though :\

I did do that with the CPU flex cable (to solder the middle part of the ribbon pins), on the v2 i did a while back but its a good shout nontheless to kapton it off on sensitive points but man....if this doesn't work....then im just selling the damned thing for spares/repairs and trying again with a new ground point....just to see if it was me/my soldering iron or that point? So many questions....I know.....pooooooooo

Yes. He went on and on about how good his grinder was and that he "can't work without it" So Logically I thought it was the solution to any tough solder point.
