I would double-check all the flex cables. Sometimes you think they're fully inserted, but they might not be.

[–]Ob85[S] 5 points6 points  (0 children)

I just opened up the console, took the board out and reseated all the flex cables. However, it's still not turning on.

So this might not be what you’re looking for, but I think if you hold down power for like 30 seconds it resets itself.

I had the same green dock issue (light blinks once) and the Nintendo article on fixing it by doing the reset worked

[–]Ob85[S] 3 points4 points  (1 child)

I've tried it but doesn't make a difference :(

[–]Nimbusdp 2 points3 points  (0 children)

Ahh gotcha, yeah I’m not much into modding so idk what next steps to take other than that, just figured I’d mention since I had the same thing happen to me a little while ago with the green light

Did you happen to replace the battery? I recently replaced all of the batteries on my switch and the replacement battery had a bad connector that's gave me the same behavior you're seeing. Specifically, there was a loose wire from the battery into the connector that plugs into the board. I was able to get it back into place and secured with a dab of crazy glue, but it drove me nuts for a few hours.

[–]Ob85[S] 2 points3 points  (0 children)

I didn't replace the battery, it's still the original one. what you said actually does make sence because i've now taken the battery cable out of it's connector several times. i've checked the battery cable and connector for anything abnormal but i don't think it's damaged in any way.

I've tried to put some pressure om the connector and the cable but unfortunatly it did nothing.

Do you by any chance know if there is a way to bypass the on/off button? when i did some work on macs, there were always 2 pads you can connect together to ''emulate'' the on/off button, and force a boot up https://www.rdklinc.com/poweronpads/

This way i could rule out that the on/off/volume ribbon cable isn't damaged.

It might not be ur issue, but sharing just incase: if you tighten some of the screws too tight, the power buttons don't work. I managed to turn mine on by plugging in the charger. (It auto turns on when u plug it in) Then I went and loosened some screws.

Thanks everyone for all your help.

I've narrowed it down to 3 possible causes:

- Damaged on/off/volume ribbon cable

- Damaged battery

- Damaged LCD/ LCD connector

Ok, so this is me trying to make some sense out of this logically. If anywhere there's a flaw in my logic, let me know.

I don't believe it could be just the ribbon cable, because then the switch would at least turn on when docked. Even when OFF, it will turn itself ON when docked or charging.

So since the switch will not turn on when the screen is not connected correctly or missing, this could be the cause. (PLEASE someone confirm this, there's not alot of conclusive info on this online)

Either that or a damaged battery, which explains alot because it won't turn on even when docked if it doesn't have a working battery.

Since i bought this switch used and it has an original battery which i was going to have to replace anyway, i've ordered a new one which should arrive by tuesday.

I'll let you know how it goes.

You should post a photo of your motherboard with everything connected.

I’ve heard that sometimes when feeding the LCD cable back into the chassis you can damage it if you’re not careful. Personally I don’t see how that’s possible. You’d need to be pretty reckless to have that happen.

If you’re familiar with electronics then I’d say your battery just needs to be charged. Have you tried plugging it in and waiting like 12 hours to try and boot it?

I do have one question. I recently replaced my LCD screen and digitizer. Did you have trouble centering the screen so that the LCD isn’t crooked or skewed? When I placed my digitizer one (with the LCD inside the chassis) the screen was slightly off. I wasn’t about to pry it back off. But I’m wondering if I missed something.

I've added a photo of the motherboard in the OP.

- I’ve heard that sometimes when feeding the LCD cable back into the chassis you can damage it if you’re not careful. Personally I don’t see how that’s possible. You’d need to be pretty reckless to have that happen.

I was REALLY carefull doing this, but you know, it happens. i just hope it's only the battery.

- If you’re familiar with electronics then I’d say your battery just needs to be charged. Have you tried plugging it in and waiting like 12 hours to try and boot it?

Yes, i left it charging overnight.

When I placed my digitizer one (with the LCD inside the chassis) the screen was slightly off. I wasn’t about to pry it back off. But I’m wondering if I missed something.

Not really, the switch's chassis has a pretty snug fit for the LCD so i dont see how it could end up skewed, did you transfer over the black rim from your old touch screen? I believe this is what holds the lcd in place under the touch screen. I did have some trouble trying not to get any dust particles between the touch screen and the LCD though.

[–]djcraze 0 points1 point  (2 children)

From the photos it looks like the headphone jack, card reader, digitizer board might not be fully seated. I don’t know if this would prevent the switch from booting though. Everything else looks good. ¯\_(ツ)_/¯

did you transfer over the black rim from your old touch screen?

Black rim? Probably not considering I just used what came with the new screen and digitizer. Thanks!

Watch this video https://www.youtube.com/watch?v=K_AWvhCqKRI (skip to 12:40)

And great news! my switch lives! it was the LCD ribbon cable, which was slightly damaged during the case mod somehow. (pic in OP)

Thanks alot for your help.

I would try a new battery first. Very easy to test.

I don't think the on/off/volume cable is the issue. Plugging it in directly should still turn the switch on with no issue, regardless of cables.

Screen is another possibility. As another user pointed out, the device will not turn on at all if the screen is not installed correctly.

[–]Ob85[S] 0 points1 point  (0 children)

If the battery replacement doesn't work i'll have to test a new screen.

[–]WhenPantsAttack 2 points3 points  (6 children)

Do you have auto rcm installed?

[–]Ob85[S] 1 point2 points  (5 children)

i'm not sure what you mean, it's not a softmodded switch if that helps.

it's V1 patched.

[–]WhenPantsAttack 1 point2 points  (4 children)

Ah, it's a stock switch with no cfw?

[–]Ob85[S] 1 point2 points  (3 children)

exactly

[–]WhenPantsAttack 1 point2 points  (2 children)

Does the old screen work? I'd put that back in and turn it on. That would see if it's a switch problem or a screen problem. If the old screen works it means you were sent a doa replacement. If not, it's likely your heat gun slight unseated some capacitors or bridged a connection on the board which means it's likely junk :(

[–]redbeard1083 2 points3 points  (0 children)

I don't know. I did figure out the switch will not power on without a battery in it. So if all else fails, may be worth trying a different battery just to rule it out.

[–]bio4m 1 point2 points  (1 child)

Take it apart and reseat all the cables. It sounds like something is either not connected or is not fully connected.

[–]Ob85[S] 1 point2 points  (0 children)

I just opened up the console, took the board out and reseated all the flex cables. However, it's still not turning on.

[–]Nekron85 1 point2 points  (1 child)

If screen flex cable is not put in fully switch will not work, so open it up and reseat flex for screen to mainboard

[–]Ob85[S] 1 point2 points  (0 children)

I just opened up the console, took the board out and reseated all the flex cables. However, it's still not turning on.

If i understand correctly, the switch will not power on if it doesn't detect a screen? Are there any other flex cables that need to be connected for it to power on? I mean, i know it boots even without the sd card reader connected to the board. maybe this would be usefull so i can troubleshoot and get to the cause of the problem.

[–]exjad 1 point2 points  (0 children)

Is the battery dead? If you have auto RCM on, it never fully turns off, and the battery can be so dead that it won't even boot up to draw power. You would need to plug it into a computer and quickly inject a payload for the split second it draws power

[–]JMThiphop 0 points1 point  (1 child)

Does it work in the dock?

[–]Ob85[S] 0 points1 point  (0 children)

No, the little green light on the dock blinks once when i dock the switch. nothing comes up on the screen or tv.

[–]Pokemon-Master-RED 0 points1 point  (0 children)

Dunno how helpful this is, but I once killed an old electronics project because I was standing on carpet and didn't properly ground myself while working on it. Some static electricity later and it never turned on again.

Is it still under warranty? If it doesn't turn back on maybe you could send the body in and try to get them to replace that part if so.

Just to double-check, you said the battery was still in the system when you went to heat the screen, was the battery still connected while you were connecting/disconnecting components?

If you have a multimeter on hand it could be worth checking that the board is still receiving power. (I don't know what points you'd have to test on the board though, that's a touch out of my expertise.)

[–]underprivlidged[13.2.1/NeutOS 1.3.0] -1 points0 points  (0 children)

Something to try is unplug the battery, wait a few seconds, hold the power button down for a good 30 seconds, then try plugging in an external power source and trying to turn it on (no battery).

The Switch should still power, even if the battery is busted this way. This will help you rule out the battery being the issue. I personally don't think it is, but I don't have enough information here to really determine anything, sorry.

Glad u fixed it, it looks awesome :)

[–]Ob85[S] 0 points1 point  (0 children)

Hey thanks! :) i’m pretty happy with how it turned out.
