SECTION 1
SERVICING NOTE
SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, screws,
and all other exposed metal parts for A C leakage. Check leakage as
described below.
LEAKAGE
The AC leakage from any exposed metal part to earth Ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microampers). Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a V OM
or battery-operated A C v oltmeter. The “limit” indication is 0.75
V, so analog meters must have an accurate low-voltage scale.
The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are suitable. (See Fig. A)
To Exposed Metal
Parts on Set
RV101 of MAIN Board
RV101 of the MAIN board requires no adjustments. Please note
that it should be dixed to mechanical center position when you moved
and do not know origin position.
L702 of PLL board
Do not touch the L702 on the PLL Board because it is not needed to
adjust.
Connection and Test Disc
Connection of this unit to a AC-3 Dolby surround equipment will
realize outstanding sound playback.
Check if the respective surround channel outputs are playing back
normally by the following method.

Discription Part No.
AC-3 TEST LD J-2501-132-A
Connected Equipment:
AC-3 LD player
(This unit is also compatible with the digital versatile disc player
(DVD). The D VD must be checked with the LD player using all
the circuits of this unit.)
Connecting Method:

SECTION 3
TEST MODE
[Self-Diagnosis and Test Mode]
This unit is provided with a “self-diagnosis and self-recovery function” which detects DSP errors and automatically recovers the unit,
and a test mode for performing operation checks during repairs.
1. Main Functions
1. DSP Error Messages
2. Various operation check mode
3. Initialization
2. Entering the Test Mode
While pressing the DIGITAL 2 button and ANALOG button
simultaneously in the power OFF state, press the POWER button.
1. DSP Error Messages
When errors occur in the DSP , the y are displayed on the fluorescent
display tube.
(Refer to Table 1 for the error messages displayed.)
Table-1:
Cause of error
(Display)
1 Failed in initial
booting
(BOOT ERROR)
2 DSP does not
operate
(RPLY ERROR)
Mostly due to faulty connection (soldering)
between DSP and microprocessor
Faulty DSP clock (X102 and onwards), faulty
DSP part, etc.
Possible cause
3. Initialization
After executing the test mode, be sure to perform initialization.
When the POWER button is pressed while pressing the DIGIT AL 1
button and DIGITAL 3 button, “All Clear!” is displayed on the
fluorescent display tube and all internal settings are initialized.
[Fluorenscent Display Tube All Lit]
With the power OFF, while pressing the DIGITAL 3 button and ∨
button togher, press the POWER button to turn ON the power.
The fluorenscent display tube all lit modewill be set.

(VRFY ERROR)
Overrunning of DSP due to heat, microprocessor bugging, or IC701 (PLL board PLL) is
faulty
Faulty DSP part, or faulty microprocessor part,
etc.
2. Operation Check Mode
• During the operation check mode, functions can be set by press-
ing the corresponding button. (See Table-2.)
• When a button other than those displayed in Table 2 is pressed,
press the POWER button to exit the check mode.

Outputs the Lch DIGITAL-2 input signal
to the REAR Lch and the Rch to the REAR

Function
[Key Check Mode]
When the POWER button is pressed while pressing the DIGITAL 1
button and ANALOG button, “KEY CHECK:12 KEYS” is displayed on the fluorescent display tube and the key check mode is
set.
When the POWER button is pressed during this mode, the number
at “12 KEYS” is counted down. When all other b uttons are pressed,
the number stops at “00 KEYS” (Note: The number is not counted
down when buttons already pressed once are pressed again.).
To exit the mode, press the POWER button and turn OFF the
power.

input signal to the FRONT Lch, REAR
Lch, CENTER, and the Rch to the FRONT
Rch, REAR Rch, and CENTER.
