multimeter handy?

#

as noted elsewhere, your F1 fuse is missing. it was likely dislodged when you installed the switch.

you're gonna need a new fuse. without it, the GBA won't turn on at all.

well, it's a moot point, as the fuse F1 is missing.

cedar galleon
#

Idk about the fuse, the fuse does seem to be there. I’m not sure what’s missing

What is it supposed to look like

copper river
#

unless you soldered it back on in the time between when Kotomi noticed it and now

cedar galleon
#

Nah its gone. Probably wont find it either

copper river
#

the good news: they're plentiful and cheap.

the bad news: the shipping isn't.

slightly better news: if you order a bunch of them and some other random things like a capacitor kit, you an get a reduced shipping charge and have replacements for any future issues that come up later

Would something like this work?

Ok yeah it just has a different letter. I’ll try these ig

copper river
#

you need a specific type.

#

oh, they are out of stock, one moment

#

I’ll check it out

cedar galleon
#

Bought 5 of them. They’re cheap anyway

I also wouldn't recommend using those switch adapter boards. The PCB is fine, but the tiny switch will eventually fail, it's just not rated for this kind of use.

Still doesnt turn on

Get your multimeter and make a continuity test on these points

The two pins circled in pink DO beep but not when connected with c43

Orange circled doesnt work at all nor red

#

All right
Well you're gonna need to remove it - do you have a hot air station ?

#

The Issue is that your installation is not aligned

Removing it will require some gear (hot air station) or good experience
I don't recommend you try the "hot air less" approach

Where are you located ?

About all of the module
I would recommend you make a post in #1049401311101206649 to ask someone to do it for you
Share a link of this topic so they are filled in with what we know so far

#

It may be disappointing not to be able to finish it up yourself, but at this point I'm confident you would destroy the traces under the module
Not to mention this might no be the only issue, as there's some solder spill here and there

#

I double that, if even the red points don't beep, something went seriously wrong, and removing this power switch without hot air or hot plate is a recipe for disaster.

Can you post the link for that replacement switch? I'm curious to see how the pcb looks like

#

I'm guilty of using them in the past, but the tiny replacement switch just isn't up for the job

Can also use a nds power switch, you have to remove the spring inside though

cedar galleon
#

I’m aware that the switch works i just dont fully understand what went wrong

#

we can only guess at this point. I'm assuming that either the switch is misaligned, or it's not soldered correctly, but either way, there's no electrical contact in points where there must be contact

strange briar
#

I have revised my judgement, it's not nicely aligned but it's not a mess either

Could you re-heat each of the 4 pads, adding some flux and a bit more solder ?

#

I also think that's the issue, the solder didn't reach the bottom because it requires more heat time, or the surface tension won't make it go down

cedar galleon
#

Idk what the issue is since the switch beeps properly.

You don't happen to have some pictures of "before" the install, do you ?
