Let’s start with the simplest – and gradually move on to the difficult cases when you need to disassemble the remote or reset the settings of the TV.

1.Batteries: Why even new ones might be to blame

The first thing that comes to mind is to replace the batteries, but even here there are pitfalls, like the contacts in the remote compartment oxidize over time, and even fresh batteries don't give the desired voltage, or you bought cheap alkaline cells that lose power in a week.

What to do:

• 🔋 Insert new batteries (preferably lithium) CR2032 oralkaline AAA from trusted brands: Duracell, Energizer).
• 🧹 Wipe the contacts in the remote compartment with a cotton swab with alcohol - oxidation looks like a green or white plaque.
• 🔄 Turn batteries in places (unless they are symmetrical) – sometimes helps with poor contact.
• 📏 Check the polarity: on Xiaomi Plus remotes (+) usually on top, but in some models (e.g., Mi). TV Stick could be the other way around.

• 💧 Liquid intake – even a couple of drops of tea can cause corrosion on the board.
• 🐶 Bitten wires (if there are animals at home) – check the plume connecting the board to the buttons.

How to diagnose:

1. Turn on your phone and point the IR diode at the remote (usually at the top, under transparent plastic). Press any button — if the diode is working, you'll see a purple flicker on your smartphone screen. No flicker? So the problem is the board or diode.
2. Take apart the remote (take care of the latches with a flat screwdriver) and check: Integrity of the tracks on the board (whether there are cracks or blackenings). Button contacts - they should be clean, without oxidation.

If we found damage,

• 🔧 Cut off button contact – can be restored with conductive glue (for example, Permatex).
• 💡 Burned LED - replace it with a new one (any IR diode with a wavelength of 940 nm will do).
• 🚿 Corrosion from liquid - clean the board with isopropyl alcohol and dry with a hair dryer (not hot!).

💡

If the remote is falling into water, don't dry it on a battery or under the sun, which can warp the plastic and damage the chips, but put it in a bag of silica gel (out of a shoebox) for 24 hours.

3.Television problems: why it doesn't respond to the remote
