Replacement tools and materials
Before you start disassembling, prepare everything you need, and the lack of the right tools is the main cause of damage to the body or internal components.
- 🔧 Plastic blades (2-3 pieces) - for disconnecting latches without scratches.
- 🔨 Screwdriver. T5/T6 — for back-mounting screws.
- 🧲 Magnetic mat - so as not to lose small details (screws, latches).
- 📦 New top panel – be sure to check compatibility with the model (for example, for Mi). TV 555" will only fit the original part with art. MDZ-22-AB).
- 🧴 Isopropyl alcohol (70%+) — plume-cleaner.
- 📏 Tweezers - for careful extraction of plumes.
If your model has a glue fixation (for example, Redmi). TV A2), additionally:
- 🔥 Building hair dryer - to soften glue.

Step-by-step: Removing the old panel
The dismantling process depends on the design of the TV, and below is a general guide that is suitable for most Xiaomi models (except for the non-disassemblable ones).
Step 1: Disconnection and preparation
Turn off the TV and put it down on a soft surface (like a towel) and make sure there's enough room to maneuver around. If the TV was hanging on the wall, remove the mount. VESA.
Step 2: Removal of the back cover
Unscrew all the screws around the perimeter of the rear panel (usually 8-12 pieces). TV 4S) The screws are hidden under rubber plugs, put a blade on them, then carefully remove the lid by pulling it up.

Step 3: Disconnecting the plumes
Under the lid, you'll see the control board and the plumes going to the top panel.
- 🔌 Power/volume button plume – usually white or grey.
- 🎤 The microphone plume (if any) is thin, with a red mark.
- 📶 IR receiver – can be soldered or connected by a separate cable.
Carefully unplug the plumes by pulling the plastic connectors (not the wires!). If the connector is tight, use tweezers. Don't make an effort -- in the Mi models. TV 5 Pro plumes are fragile and can break.
Step 4: Dismantling the top panel
Now, let's move on to the panel itself, depending on the model.
- 🔄 Latches (most models): insert a plastic blade into the gap between the panel and the body and carefully guide it along the perimeter, snapping the mounts. Start at the corner.
- 🧴 Clay. TV A2, some Mi TV 4A): warm up the edge of the panel with a dryer (temperature 60-70)°C) and slowly pull it back with a spatula.
If the panel doesn't respond, don't use force -- you may have missed the hidden latch. See the spoiler with a photo of the typical mounts.

⚠️ Note: In the TVs Xiaomi with OLED-matrix (e.g. Mi) TV Master OLED) The top panel is often attached to the matrix itself. If you don't properly dismantle it, you can damage the screen.
Installation of a new panel and assembly
When the old panel is removed, clean the seat of dust and glue residue (use isopropyl alcohol).
- 🔍 Compatibility of connectors – plumes should fit perfectly in shape.
- 📏 Holes under screws / latches - compare with the old panel.
- 🎨 Color and texture – some lines may differ in color.
The installation is carried out in reverse order:
- Connect all the plumes to the board (start with the IR receiver and microphone, if any).
- Place the panel in place, starting at the top edge. For latch models, push until you click.
- If the panel is glued, apply a new two-sided tape and press tightly for 30 seconds.
- Set the back cover and twist the screws (do not pull!).
After assembly, turn on the TV and check:
- ✅ Are the power and volume buttons working.
- ✅ Does the remote (IR receiver) react).
- ✅ Do you have any extraneous sounds (crunch, creak) when pressing the panel.
💡
If the TV doesn't turn on after you change the panel, check the connection of the power plume to the motherboard. In 30% of cases, the problem lies in poor connector contact. CN502 (See the diagram in the user manual).
Frequent Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes when replacing the top panel, and here are the most common problems and ways to prevent them:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use of metal tools | Scratches on the body, damage to plumes | Use only plastic shoulder blades |
| Application of force upon disconnection of plumes | Contact breaks, broken buttons | The connectors open upwards, not sideways! |
| The wrong temperature when heating glue | Melting plastic, deformation of the panel | Keep the hair dryer at a distance of 10-15 cm, do not heat one point longer than 10 seconds. |
| Forgot to move the IR receiver. | The remote is down. | Check for a small black part on the old panel |
Another common problem is the incompatibility of the panel being replaced. TV 5 55's not good for Mi TV 5 Pro 55" because of the different microphone connectors. Always check the art number (on the back of the original panel sticker).
If the TV is replaced with a "No Signal" error or the light flashes, the matrix plume is probably damaged.
- Turn off the TV.
- Remove the back cover and check the plume connection LVDS (white-panel).
- Clean the contacts with alcohol and connect again.
💡
If you don't turn on after you change the panel, 90 percent of the time, it's the power plume or the buttons that are not in contact, and don't panic, take it apart and check the connections again.

Alternative solutions: repair instead of replacement
If the top panel is not critically damaged (such as small scratches or cracks), it can be repaired instead of being completely replaced.
- 🖌️ Scratches: Use plastic polyreole (such as Displex) or a special pencil to mask scratches (select the color under the panel).
- 🔧 Cracks: For small cracks, liquid plastics (like Loctite Plastics Bonding System) can be used.
- 🎨 Paint the panel with a special paint for plastic (for example, Motip Dupli-Color.
- 🔥 Fractured elements: glue the broken part with Cosmofen superglue CA-12 (leaves no trace on plastic).
For models with detached coating (for example, soft touch panel on Mi) TV Master, you can help you re-paint vinyl, match matte or glossy vinyl to the color of your TV, and stick it with a rakel).
⚠️ Warning: Do not use acetone or solvents based on it to repair the panel - they corrode Xiaomi plastic, leaving white spots. Also avoid heating above 80°C (e.g. iron) so as not to deform the panel.
If the damage is severe (for example, broken mounts for the matrix), repair may not be advisable, in which case it is better to buy a new panel or contact the service.
