• 🕸️ Web of cracks with display disturbances (color stripes, flickering, black spots).
• 👆 The sensor does not respond on touch or works partially (for example, only the upper half).
• 🔥 "Dead pixels" — permanent colored dots that do not disappear upon reboot.
• 🖥️ Image Artifacts: ripples, color distortions, “snow” on the screen.
• 💥 Complete absence of image when the backlight is on (a dim glow is visible).

Before replacing, check to see if the problem is caused by a software glitch. To do this:

3. Disconnect the battery cable (black connector) - this will de-energize the board.

What to do if the cable does not disconnect?

If the connector is stuck, do not pull it by force. Heat the area with a hairdryer (40–50°C) and gently rock the train left and right. If the contacts are bent, replace the cable (cost 300–500 ₽).
