1. Precaution
7) Some TV chassis are shipped with an additional secondary grounding system. The secondary system is adjacent to
the AC power line. These two grounding systems are separated in the circuit using an unbreakable/unchangeable
insulation material.
8) When any parts, material or wiring appear overheated or damaged, replace them with new regular ones immediately.
When any damage or overheating is detected, correct this immediately and make a regular check of possible errors.
9) Check for the original shape of the lead, especially that of the antenna wiring, any sharp edges, the AC power and the
high voltage power. Carefully check if the wiring is too tight, incorrectly placed or loose. Never change the space
between the part and the printed circuit board. Check the AC power cord for possible damages. Keep the part or the
lead away from any heat-emitting materials.
10) Safety Indication:
Some electrical circuits or device related materials require special attention to their safety features, which cannot be
viewed by the naked eye. If an original part is replaced with another irregular one, the safety or protective features will
be lost even if the new one has a higher voltage or more watts.
Critical safety parts should be bracketed with (
,
). Use only regular parts for replacements (in particular, flame
resistance and dielectric strength specifications). Irregular parts or materials may cause electric shock or fire.
