Actually, it looks like it’s been removed

ant-man help!!

It looks like the right model, at least there're "8342" numbers written. You need microscope for soldering these, better go with Flex cables if you aren't confident yet.

they are 2mmx2mm, better than a 0201 cap if you meant to deal with

It is correct. That is why i said its the most difficult one. I am using hdmi microscope to solder it. Can't imagine only using magnifying glass, or only using direct eye.

won't burn? when soldering to the mosfet?

:v

I doubt it will be too long before they are back on there

....question:
does picofly detect if LCD is functioning or not? does it have an effect on pico's operation?

the locking mech on the LCD (?) flat cable came loose and i think this is what causing the PINK LED (?) have to test further...

but when i applied pressure on the connector (still without the locking mech) lite lcd still working ( thank God! )

..now how to put the locking mech back....

If you want some cheap stuff, you might used old LG G5 handphone

Its difficult, need experience. Use lot of flux, to spread the heat.

If you want a cheap solution, use handphone. Lot of 2nd smartphone has a decent camera. This is the maximum zoom LG G5 could take. I use it to photo the switch and the voltage regulator rp2040 i took off. Its better than using direct eye, or magnifying glass. If you lucky you could get a 2nd G5 for only around $20.

yes. i tested zoom using my smartphone....

did you use heatgun ? or just regular soldering iron ?
for the mosfet?

that's not LCD connector but its the backlight and left side D-PADS and power button

ohh, thought it was... although i wonder if that being disconnected has an effect on the Pico, hence me getting Pink LED after checking all wires are OK...?

..I'll try to re assemble again tomorrow (2 am here)

No, nothing else would effect on pico except the soldering. The glitch sequence still works with only battery connected+power button push

Thanks, I'll try again tomorrow...

Have you tried 'Warmboot Error Fix' to boot to ofw?

Tried it. It didn't work. Still a black screen a second after the logo appears.

Gud day all. I'm new here just moded my switch v2 (mariko) using picofly in which a cpu capacitor (SP2) got remove/damage i would like to ask what is the value and its ok for it not to be replaced?

 

[LogicalMadness]

Thanks, I'll try again tomorrow...

It is POSSIBLE but WAAAAYYYY closer to impossible to put JUST the latch back. In my experience, the whole connector needs to be replaced. Not an easy task to solder plastic pieces, you need more tools than just an iron (I use a bottom\pre-heater and air wand).

I have seen people make different 'hacky' solutions work, though. EG shove a small piece of plastic in w\ the ribbon and then tape\glue the whole thing down.

GL!

Do you have any photos of how it turned out?
