• Design and specifications can be subjected to changewithout notice.

• Safety Check after Servicing

Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wireshave been returned to original positions. Afterwards, perform the following tests and confirm the specified values in orderto verify compliance with safety standards.

1. Insulation resistance testConfirm the specified insulation resistance or greater between power cord plug prongs and externally exposed parts ofthe set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphonejacks, etc.). See table below.

2. Dielectric strength testConfirm specified dielectric strength or greater between power cord plug prongs and exposed accessible parts of theset (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks,etc.) See table below.

3. Clearance distanceWhen replacing primary circuit components, confirmspecified clearance distance (d), (d') between solderedterminals, and between terminals and surroundingmetalic parts. See table below.

Table 1: Rating for selected areas

* Class II model only.Note: This table is unofficial and for reference only. Be sure to confirm the precise values for your particular country and

locality.

4. Leakage current testConfirm specified or lower leakage current between B (earth ground, power cord plug prongs) and externally exposedaccessible parts (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks,earphone jacks, etc.)

Measuring Method: (Power ON)Insert load Z between B (earth ground, power cord plugprongs) and exposed accesible parts. Use and ACvoltmeter to measure across both terminals of load Z.See figure 2 and following table.

Table 2: Leakage current ratings for selected areas

Note: This table is unofficial and for reference only. Be sure to confirm the precise values for your particular country andlocality.

• When change the parts which are out of order, first, remove the power plug from the socket and then discharge thevoltage across between both terminals of C807. (Use an external scores of KΩ resistance)

• When check the primary circuit by using the oscilloscopes insulate the oscilloscope surely. (Use the isulatingtransformer) and must connect GND into the primary GND), (But there is no connection when check the secondarycircuit).

• When change IC801, check FUSE and Cement resistance surely.
