Diagnostika probl\u00e9mu<\/p>\n

Prvn\u00edm krokem je p\u0159esn\u00e1 diagnostika probl\u00e9mu. Je nutn\u00e9 ur\u010dit, co p\u0159esn\u011b nefunguje. Je sn\u00edma\u010d zcela nefunk\u010dn\u00ed, nebo vykazuje pouze sn\u00ed\u017eenou citlivost \u010di zkreslen\u00ed sign\u00e1lu? Zkontrolujte kabel\u00e1\u017e, konektory a samotn\u00e9 p\u0159ipojen\u00ed sn\u00edma\u010de k \u0159\u00edd\u00edc\u00ed jednotce.

Oprava po\u0161kozen\u00e9 kabel\u00e1\u017ee<\/p>\n

Pokud je probl\u00e9m v po\u0161kozen\u00e9 kabel\u00e1\u017ei, je oprava relativn\u011b jednoduch\u00e1. Je nutn\u00e9 identifikovat m\u00edsto po\u0161kozen\u00ed, odstranit po\u0161kozenou \u010d\u00e1st kabelu a propojit zdrav\u00e9 \u010d\u00e1sti.
