    • One 2.5 mm-long screw on the top edge of the device

    • Two 2.5 mm-long screws on the bottom edge of the device

    • To prevent these tight screws from stripping, apply firm downward force, work slowly and try another JIS 000 or PH 000 driver if the screws won't come out.

    • Open the game card cartridge flap.

    • The game card cartridge flap attaches to the other half of the plastic shell, preventing you from completely lifting up the rear panel if it's closed.

    • Use your fingers or a pair of tweezers to lift the microSD card reader straight up from the device to disconnect and remove it.

    • During reassembly, make sure the press connector underneath the foam pad is firmly connected to the motherboard. It may help to remove the foam pad before reinstalling the card reader.

    • Use a JIS 000 screwdriver or an official iFixit PH 000 driver to remove the six 3 mm screws securing the shield plate to the device.

    • Use your fingers or a pair of tweezers to peel back the piece of foam on the top edge of the device near the fan exhaust port.

    • If the foam doesn't easily peel away, don't force it as it might end up tearing. Carefully peel at different spots to pull back the foam.

    • Insert a spudger underneath the shield plate along the edge of the device.

    • Pry up to lift the shield plate and remove it from the device.

    • You may feel a bit of resistance. This is normal, since the shield plate is slightly bonded to the heat sink with thermal paste.

    • A thick pink thermal compound bridges the gap between the shield plate and the copper heat sink underneath. This helps prevent the Switch from overheating.

    • You can reuse the pink thermal compound if you're careful. Keep the compound clean and make sure it makes solid contact between the heat sink and the shield during reassembly.

    • If you need to replace it, refer to our thermal paste guide to remove the old thermal compound and replace it with an appropriate compound, such as K5 Pro, during reassembly.

    • Use the point of a spudger to pry the battery connector straight up and out of its socket on the motherboard.

  15. Nintendo Switch Left Joy-Con Rail Replacement, Remove the heat sink: paso 15, imagen 1 de 1
    • Use a JIS 000 screwdriver or an official iFixit PH 000 driver to remove the three 3 mm screws securing the heat sink to the motherboard.

    • Carefully peel the two foam pieces stuck over both the heatsink and the fan away from the fan.

    • The foam only needs to be peeled back enough to clear the fan.

    • The foam is really delicate and tears easily. Use the following technique to peel the foam:

    • Insert the point of a spudger underneath the part of the foam that isn't stuck against anything,

    • Press the top of the foam with your finger to hold it in place.

    • Roll the spudger tip underneath the foam all the way to the other end of the foam to release it.

    • Use a spudger or your fingers to lift the heatsink up and off the motherboard to remove it.

    • You may feel a bit of resistance. This is normal, since the heat sink is slightly bonded to the CPU with thermal paste.

    • Clean off the old thermal paste from the heat sink and CPU using high-concentration (90% or higher) isopropyl alcohol and a microfiber cloth. Apply new thermal paste to the CPU before reassembly.

    • Apply thermal paste to all surfaces that had thermal paste applied previously. This includes between the heatpipe and aluminum shield, which the Switch uses as additional heatsinking.

    • Use an opening tool or your fingernail to flip up the small, hinged locking flap on the digitizer cable's ZIF connector.

  18. Nintendo Switch Left Joy-Con Rail Replacement: paso 19, imagen 1 de 2 Nintendo Switch Left Joy-Con Rail Replacement: paso 19, imagen 2 de 2
    • Use a pair of tweezers to slide the digitizer cable horizontally out of its connector on the game card reader board.

    • Before inserting the cable during reassembly, make sure the ZIF connector locking flap is flipped up.

    • With the cable parallel to the board, gently slide it into its connector.

    • Don't force the cable into the connector. If it doesn't insert, ensure the locking flap is flipped up, reposition the cable, and try again.

    • If your touchscreen doesn't work after the repair but your Game Card reader does, make sure this cable is properly inserted. If your Game Card reader also doesn't work, check the Game Card connector in the next step instead.

    • Use the point of a spudger to pry the headphone jack and game card reader connector straight up to disconnect it from the motherboard.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend and cause permanent damage.

    • If the touch screen doesn't work and/or game cards aren't detected after reassembly, you might have not fully reconnected this press connector. Carefully disconnect it and try again.

If this was a neon Switch, this would be the rail that gets attached with the blue or the red joy con?

felipemanzur21 - Contestar

it would be the Blue joy con

Nick Heilman -

I completed this guide, but the left joy con is still not being detected after the sensor rail was replaced with a sensor rail purchased on this site. The joy con in question will attach and sync with another console, so that leads me to believe it is a fault with the switch console itself. Is there something else that I can replace that would fix this issue?

Depending on where you get your replacement rail, it may not have the silver on the ribbon cable. No worries, as I did this repair 3 months ago (Jan) and had no issues at all.

To get the ribbon cable in place, I recommend first getting the battery wires out of the way, then slightly bending it and sliding it under that section of the Motherboard. If you do it right, the end of the ribbon cable will pop up and that can be slid into place. Took some fiddling but I eventually got it to work!

No matter what, never crease your ribbon cables!

I have a joycon where it will disconnect if it is slotted all the way down. I have to push it up about 1mm for it to stay connected. The joycon works perfectly on other Switch consoles. Any idea of what troubleshooting I can try before replacing the whole rail?
