SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician.
LEAKA LEA KA GE CURRENT CURRENT CHECK CHECK Before returning the unit to the customer, customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. if the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective. Be sure to test for leakage current with the AC plug in both polarities, in addition, in each power ON, OFF and STANDBY mode, if applicable.
Please se heed heed the points list ed below below during servic ing and inspection. CAUTION Plea ◎ Heed the cautions!
◎ Inspect for safety after servicing!
Spots requiring particular attention when servicing, such as the cabinet, parts, chassis,etc., have cautions indicated on labels. be sure to heed these causions and the cautions indicated in the handling instructions.
Check that all screws, parts and wires removed or disconnected for servicing have been put back in their original positions, inspect that no parts around the area that has been serviced have been negatively affected, conduct an inslation check on the external metal connectors and between the blades of the power plug, and otherwise check that safety is ensured.
Caution ution conc erning electric electric s hock! ◎ Ca (1) An AC voltage is impressed on this set, so touching internal metal parts when the set is energized could cause electric shock. Take care to avoid electric shock, by for example using an isolating transformer and gloves when servicing while the set is energized, unplugging the power cord when replacing parts, etc.
(Insulation check procedure) Unplug the power cord from the power outlet, disconnect the antenna, plugs, etc., and turn the power switch on. Using a 500V insulation resistance tester, check that the inplug and the externally exposed metal parts (antenna terminal, headphones terminal, input terminal, etc.) is 1MΩ or greater. If it is less, the set must be inspected and repaired.
(2) Tere are high voltage parts inside. Handle with extra care when the set is energized.
Caution c oncerning disassembly and ◎ Caution assembly! Through great care is taken when manufacturing parts from sheet metal, there may in some rare cases be burrs on the edges of parts which could cause injury if fingers are moved across them. Use gloves to protect your hands.
CAUTION Concerning important safety parts Many of the electric and structural parts used in the set have special safety properties. In most cases these properties are difficult to distinguish by sight, and using replacement parts with higher ratings (rated power and withstand voltage) does not necessarily guarantee that safety performance will be poreserved. Parts with safety properties are indicated as shown below on the wiring diagrams and parts lists is this service manual. Be sure to replace them with parts with the designated part number.
◎ Only use designated parts! The set's parts have specific safety properties (fire resistance, voltage resistance, etc.). For replacement parts, be sure to use parts which have the same poroperties. In particular, for the important safety parts that are marked z on wiring diagrams and parts lists, be sure to use the designated parts.
◎ Be sure to mount p arts and arrange the wires as they were originally!
(1) Schematic diagrams ......Indicated by the z mark. (2) Parts lists ......Indicated by the z mark. Using parts other than the designated parts could result in electric shock, fires or other dangerous situations.
For safety seasons, some parts use tape, tubes or other insulating materials, and some parts are mounted away from the surface of printed circuit boards. Care is also taken with the positions of the wores omsode amd clamps are used to keep wires away from heating and high voltage parts, so be sure to set everything back as it was originally.

CAUTION IN SERVICING Before th e Digit al P.W.B. are replaced If you cannot specify the cause of the digital PWB defect, carry out "Initializing"→ "Update to latest firmware". The defect may be cleared. See the following for the method of initializing the μcom.
・
Initializing AV SURROUND RECEIVER AV SURROUND RECEIVER initialization should be performed when the μcom, peripheral parts of μcom, and Digital P.W.B. are replaced. 1. Turn off the power using ON/STANDBY button. 2. Press ON/STANDBY button while simultaneously pressing STANDARD and DSP SIMULATION buttons. 3. Check that the entire display is flashing with an interval of about 1 second, and release your fingers from the 2 buttons and the microprocessor will be initialized. Note:
If step 3 does not work, start over from step 1. All user settings will be lost and this factory setting will be recovered when this initialization mode. So make sure to memorize your setting for restoring after the initialization.

DISASSEMBLY • Disassemble in order of the arrow of the figure of following flow. • In the case of the re-assembling, assemble it in order of the reverse of the followingflow. • In the case of the re-assembling, observe "attention of assembling" it. • If wire bundles are untied or moved to perform adjustment or parts replacement etc., be sure to rearrange them neatly as they were originally bundled or placed afterward. Otherwise, incorrect arrangement can be a cause of noise generation. TOP COVER
