Why you might need to disassemble the Xiaomi remote TV

Remote controls from Xiaomi TVs (including Mi models) TV 4/4A/4S/5/5X, Mi Box S and Mi TV Sticks get stuck over time, the buttons get stuck, the reaction gets sluggish, and sometimes the device stops working altogether. 80% In some cases, the problem is not the electronics, but the contamination of the contacts or the wear of rubber gaskets:

โœ” Restore efficiency without buying a new one (savings of 1,500โ€“3,000) โ‚ฝ).

โœ” Clean the board of dust, crumbs or spilled liquid (frequent cause of malfunctions).

โœ” Replace buttons or rubber matrix layer if they are worn out.

โœ” Diagnose the breakdown before contacting the service (for example, check the battery compartment for oxidation).

This article is a step-by-step analysis of the features of Xiaomi remotes, including hidden latches that are easy to break when you open a sloppy opening, and we will look at the tools, nuances for different models and give tips on how to avoid typical errors.

What tools will be needed to disassemble

Xiaomi doesn't need professional kits to open the remote accurately -- there's enough tools at hand -- but the wrong tool can leave scratches on the plastic or break latches.

  • ๐Ÿ”ง Plastic blade (or mediator) - to separate the halves of the body without scratches.
  • ๐Ÿ”จ Cross screwdriver (size) PH0 or PH00) โ€” for screws in some models (for example, Mi Box S).
  • ๐Ÿงด Isopropyl alcohol (90%+) โ€” Cleaning contacts and fees.
  • ๐Ÿงป Cotton swabs and wipes - removing dirt and fat.
  • ๐Ÿ“ฆ Container for small parts - so as not to lose springs or screws.

โš ๏ธ Warning: Do not use metal screwdrivers to separate the body, they leave traces and can damage plastic guides. If you do not have a plastic blade, old bank cards or even a guitar transmitter will do.

For models with adhesive connection (for example, some Mi remotes) TV Stick may need a dryer to soften the glue. Heat the case to 40-50ยฐC (not higher!) and gently tuck the seam with a spatula.

Step-by-step: how to disassemble the Xiaomi remote TV

The process of disassembling Xiaomi remotes is similar to most models, but there are nuances. Below is a universal instruction with hidden latches and typical "traps." If your remote is in the Mi series. TV 4X or Mi Box S, please note the section on the features of the models.

Step 1: Battery recovery and visual inspection

Before disassembly it is necessary:

  1. Turn the remote and move the battery compartment cover (on most models it is fixed by a latch).
  2. Remove the batteries and inspect the contacts for oxidation (green coating), if you have one, clean them with a cotton swab dipped in alcohol.
  3. Check the springs, they must be elastic. If the spring is bent, straighten it carefully with tweezers.

Step 2: Separation of the hull

Xiaomi's remote body consists of two halves held together by latches to separate them:

  1. Insert a plastic blade into the seam between the halves of the body (start on the side of the battery compartment).
  2. Carefully drive the blade along the seam, alternately snapping the locks. Do not force - if the body does not respond, then you missed the latch.
  3. After cracking 2-3 latches on one side, repeat the process from the opposite side.

โš ๏ธ Attention: The Mi remotes TV 5 Pro and Mi TV Stick has an additional latch under the button OK. If you don't crack it, you can break the plastic lock!

Step 3: Removing the board and rubber matrix

After the separation of the body, you will see:

  • ๐Ÿ–ฅ๏ธ Printed circuit board with chip and infrared LED.
  • ๐ŸŸฆ Rubber matrix with buttons (it can stick to the board).
  • ๐Ÿ”‹ Battery compartment contacts (sometimes soldered to board).

Carefully remove the rubber matrix โ€” it often sticks to the contacts. If the buttons are suffocated or erased, the matrix can be replaced (sold on AliExpress for 200-400). โ‚ฝ). Remove the fee by holding the edges so as not to damage the tracks.

What to do if the button fell off the rubber matrix?
If the button (the rubber bump) has come off the matrix, you can glue it back with cyanoacrylate glue (superglue). Put a drop of glue on the base of the button, press it to the matrix and hold it for 30 seconds. After drying (10-15 minutes), check the operability. If the button is not fixed, order a new matrix - the repair will be unreliable.

Step 4: Clearing Contacts and Payments

This is the most important step. Contaminated contacts cause 90 percent of the malfunctions.

  1. Moisten the cotton swab in isopropyl alcohol (do not use vodka or cologne!).
  2. Gently wipe the contact areas on the board (places where the rubber matrix touches the tracks).
  3. For severe contaminants, use a toothpick wrapped in cotton wool.
  4. Let the board dry for 10-15 minutes (alcohol evaporates quickly).

โš ๏ธ Warning: Don't force the board, you can wipe the tracks or damage the chip. If there's white plaque on the board, remove it with a pencil washing gum.

Step 5: Checking the infrared LED

If the remote doesn't work even after cleaning, the problem may be the IR LED.

  1. Direct the remote to the smartphone camera (enable the shooting mode).
  2. Press any button. If the LED is in good shape, you'll see the purple light flickering on your smartphone screen.
  3. If there is no flicker, the LED is faulty (replacement is required).

LED soldered to the board. You need a soldering iron with a thin stinger (25-30 watts) and solder to replace it. If you don't have soldering experience, you better contact the service.

Step 6: Assembling the remote

Collect the remote in reverse order:

  1. Place the charge in the bottom half of the body.
  2. Carefully place the rubber matrix, combining buttons with holes.
  3. Connect the halves of the body, starting from the side of the battery compartment.
  4. Click the body, evenly pressing the perimeter (you will hear characteristic clicks).
  5. Insert the batteries and check the performance.

๐Ÿ’ก Tip: If you put the buttons down after you build them, or if you put them back up again, you're going to have a rubber array that's not even.

๐Ÿ’ก

The most common build error is a rubber matrix skew, which causes the buttons to be "double pressed" or not working, and always make sure that the matrix is flat, without any clamps.

Features of disassembly for different models Xiaomi

Xiaomi remotes are similar in appearance, but have design differences, and below are the key nuances for popular models.

Model remote controlFeatures of disassemblyTypical problems
Mi TV 4/4A/4SThe case is on the latches, no screws, the hidden latch under the Menu button.Sticking the Volume buttons and OK dust-in.
Mi TV 5/5X/5 ProAn extra latch under the IR window, the plastic is more fragile.Oxidation of contacts of the battery compartment (due to humidity).
Mi Box STwo screws under the legs (cross screwdriver) PH0). Battery soldered.Breaking the power button plume with careless disassembly.
Mi TV StickThe body is glued, it requires a hair dryer. AAA (instead AA).Getting liquid under buttons (a frequent problem due to its compact size).

For the Mi Box S and Mi remotes TV There's another thing about the Stick: the power button plume often breaks off when you disassemble it. If the Power button doesn't work after you build it, check if the plume has moved away from the board. It can be soldered back neatly (you need a soldering iron and experience with small parts).

๐Ÿ’ก

If you're disassembling the Mi remote TV Stick, preheat the body with a hair dryer (temperature 40-50)ยฐC) for 1-2 minutes, this will soften the glue, and the halves will be more easily separated!

What to do if the remote does not work after disassembly

If after cleaning and assembly, the Xiaomi remote does not respond to pressing, check the following:

  • ๐Ÿ”‹ Batteries: Are they inserted correctly? Try new ones (even if the old ones "seem to workยป).
  • ๐Ÿ“ถ TV IR port: Make sure nothing blocks the signal (e.g. decorative frame).
  • ๐Ÿ–ฅ๏ธ Matrix contacts: Perhaps the rubber gasket lies uneven or contaminated.
  • ๐Ÿ”ง Payment: Check if the items have soldered off (especially after soldering).

If the remote is partially working (for example, only some buttons are reacting), the problem is in the matrix contacts.

  1. Clean the contact areas on the board with alcohol.
  2. Wipe the graphite โ€œpetchesโ€ on the back of the rubber matrix (they can be erased).
  3. If the graphite is erased, restore it with a soft pencil (shut the spots with a griffle).

โš ๏ธ Warning: If after all the manipulations, the remote does not work, check the chip on the board. It should not be black dots (burnouts) or cracks. If they are required to replace the board (cost 500-1 200) โ‚ฝ AliExpress).
