GP0300 Installation Tutorial

Replacing the screen is a difficult and time-consuming task that is expected to take 1 to 1.5 hours. The disassembly process is also prone to damaging the game console, so we strongly recommend seeking the help of a professional repair person. Regarding changes to the whole machine maintenance policy caused by disassembly, please refer to the information officially released by VALVE.

As an additional precaution, Valve recommends entering the BIOS and adjusting the Steam Deck to battery storage mode before starting internal repairs. If you have installed a Micro SD card, please remove it before disassembly.

Before starting disassembly, please ensure that the Steam Deck battery level has dropped below 25% and has been completely shut down, and all connected cables have been disconnected. Follow the anti-static safety regulations during the operation and properly store the removed original parts. Please note that accidentally damaging a charged lithium-ion battery can cause serious danger.

During the repair process, please manage the screws properly, ensure that they are correctly placed back in their original positions, and avoid damaging the Steam Deck.

Please note that the order of the video tutorial and this document may be slightly different. They provide two different disassembly and installation sequences, both of which can ensure correct disassembly and installation of the equipment. You can choose to refer to them according to your actual situation.

Please make sure that all disassembly tools are ready, including :

        Screwdriver

        Spare Screw

        Triangular Disassembler

        Adhesive Cutting Sheet

        Sucker

        Screen Adhesive

        Storage Box

        Tweezers

The following are not included in the package and need to be prepared by yourself:

Hair dryer (or other heating products, mainly used to remove the screen)

If you have made the above preparations, please wear anti-static finger cots or anti-static gloves, and start the following replacement steps.

Use a screwdriver to remove the 8 screws on the back cover, put the 4 shorter ones in the 5.8mm screw box, and put the longer 4 screws in the 9.5mm screw box, use the triangular disassembler to open and remove the back cover of the game console.

Uncover the sticker covering the protective plate, use a screwdriver to remove the 3 screws on the protective plate, one of which is 3.4mm and two of which are 3.7mm, and take off the protective plate.

Pinch the cable or use the flat end of a spudger to push out the plug to completely disconnect the battery cable.

Open the lock on the ZIF interface, and then pull the plastic sheet on the cable to pull out the plug of the display cable.

Use a screwdriver to remove the 3 screws fixing the motherboard, they are 3.7mm.

Uncover the heat sink sticker.

Flip the motherboard and radiator 180° around the lower right corner of the motherboard to expose the display cable at the bottom of the motherboard.

When turning it over, pay attention that the speaker and FPC linked in the lower right corner of the motherboard are still connected, do not pull it too far to prevent damage.

Tear off the sticker covering the cable, pick the lock on the ZIF seat, and remove the display cable.

Flip the motherboard back to its original position , use a screwdriver to install the 3 screws that fix the motherboard, they are 3.7mm .

Use a hair dryer or other heating device to heat the surrounding area of the screen.

Note: According to our experience, if you use a hair dryer with a power of 1KW and move it around the screen 2-3 cm away from the screen, it will take about 50-80 seconds to heat up.

Fix the suction cup on the corner of the screen, as close as possible to the edge of the screen, press down to generate suction.

Use a strong and steady force to slowly pull the suction cup upwards, pay attention not to be too large, until there is a gap between the display and the frame, then insert the adhesive-backed cutting sheet, the depth should not exceed 3mm.

Cut the back glue along the screen circle, after the back glue is cut, carefully grab the right edge of the screen and lift up the screen until the screen is completely free from the frame.

When removing the suction cup from the screen, you can slightly pry the edge of the suction cup, as long as there is a small gap, you can easily remove the suction cup, avoid using brute force to pull the suction cup and the screen.

Use glue remover or alcohol (>90%) to remove any remaining residue. wipe in one direction with a lint-free cloth or coffee filter until all adhesive residue is gone.

Be careful not to use any sharp objects to scrape the remaining adhesive on the screen, as this will damage the screen coating.

Although alcohols are generally safe for use in electronics, they can dissolve some foam adhesives. Pay attention to controlling the amount used when cleaning, and do not use too much.

Allow any remaining alcohol to evaporate completely before reassembling the device.

Use glue remover or alcohol (>90%) to remove any remaining residue. wipe in one direction with a lint-free cloth or coffee filter until all adhesive residue is gone.

Be careful not to use sharp objects to scrape the residual adhesive on the middle frame, so as not to damage the middle frame.

Although alcohols are generally safe for use in electronics, they can dissolve some foam adhesives. Pay attention to controlling the amount used when cleaning, and do not use too much.

Paste the attached new screen adhesive around the middle frame, starting from the top adhesive, and tear off the film on the adhesive after pasting.

Note : Confirm the location of the adhesive before installation, avoid folding the adhesive when pasting, and avoid the adhesive beyond the frame.

There are reserved screw holes and photosensitive components on the back glue , please pay attention to avoid when pasting.

Turn the machine over, use a screwdriver to remove the 3 screws that fix the motherboard, they are 3.7mm.

Expose the display cable interface at the bottom of the motherboard, install the display cable just removed on the interface, and paste the cable.

When connecting, use tweezers to clamp the plastic sheet of the cable, push the plug in from the direction parallel to the ZIF interface, and then press the lock on the ZIF interface. During the process, avoid the plug being crooked or not fully pushed in.

When installing the display cable, be sure to confirm that the cable is fully inserted into the seat and that the contact is good. If you find that the position of the cable is shifted during insertion, please do it again.

If the screen cannot be turned on normally, please disconnect the power cable and check whether the installation steps are missing.

If the screen still cannot be turned on after checking again, please stop trying and seek professional help.

Note: In some cases after dismantling the machine, it needs to be plugged in and activated before it can be turned on.

If the screen can be turned on normally, please continue to follow the steps below after powering off.

Use a screwdriver to install the 3 screws on the protective plate, one of which is 3.4mm and two of which are 3.7mm.

Restore the sticker on the protective cover after installation.

When installing, pay attention to the heat dissipation silicone grease inside the protective cover, which is pasted on the inner wall of the protective cover for heat dissipation. Before installation, make sure that they do not fall off.

Put the back cover on, press the buckle firmly to make it close to the front cover, and fix the back cover with four 9.5mm screws and four 5.8mm screws.
