Television maintenance: troubleshooting signal loss and screen care

Common television maintenance issues include signal loss and improper screen cleaning. To resolve signal problems, users should check cable connections (HDMI, AV, antenna), verify signal sources, and ensure hardware is compatible with the DVB-T2/HEVC standard. External factors such as weather, 5G/LTE interference, and antenna positioning also play significant roles in reception quality.

For screen maintenance, it is advised to avoid glass cleaners containing ammonia or alcohol, as these can damage anti-reflective coatings on OLED, QLED, and LCD panels. The recommended method involves using a dry microfiber cloth for dust and distilled water applied to a cloth for greasy stains. Using tap water is discouraged due to mineral deposits left by hard water.
