5.Hot Chassis Warning -
a.Some TV receiver chassis are electrically connect- ed directly to one conductor of the AC power cord and maybe
earth ground. If a voltage reading in excess of 1.0V is obtained, remove and reinsert the AC power plug in the opposite polarity and again measure the voltage potential between the chassis and a known earth ground.
b. Some TV receiver chassis normally have 85V AC(RMS) between chassis and earth ground re- gardless of the AC plug polarity. This chassis can be
c. Some TV receiver chassis have a secondary ground system in addition to the main chassis ground. This secondary ground system is not iso- lated from the AC power line. The two ground sys- tems are electrically separated by insulation material that must not be defeated or altered.
6.Observe original lead dress. Take extra care to as- sure correct lead dress in the following areas:a. near sharp edges,b. near thermally hot
7.Components, parts, and/or wiring that appear to have overheated or are otherwise damaged should be replaced with components, parts, or wir- ing that meet original specifications. Additionally, determine the cause of overheating and/or dam- age and, if necessary, take corrective action to re- move any potential safety hazard.
