SERVICE MANUAL
IMPORTANT NOTICE
This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.
It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are
already known and understood by the users, and have therefore not been restated.
WARNING:
Failure to follow appropriate service and safety procedures when servicing this product may result in
personal injury, destruction of expensive components, and failure of the product to perform as specified.
For these reasons, we advise all YAMAHA product owners that any service required should be performed
by an authorized YAMAHA Retailer or the appointed service representative.
IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or recognition of any applicable technical capabilities, or establish a principle-agent relationship
of any form.
The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and
service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore,
inevitable and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to
exist, please contact the distributor's Service Division.
WARNING:
Static discharges can destroy expensive components. Discharge any static electricity your body may have
accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this
buss).
IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the
unit.

(6) DISPLAY CHECK
Check program for FL display. The display status will change as follows with submenu operation. The signal is
processed with EFFECT OFF.
For switching between internal and external sync commanded by the microprocessor, the forced external sync is
selected. (Remote control code 7A-56 : DSP/16)
All segments are turned on and off to detect defects in the FL driver (IC102) and FL display segments. Then the FL
driver operation is checked by the dimmer control.
Finally, all segments are turned on and off alternately (in lattice form), to check for a short-circuit between adjacent
segments.

The A/D conversion values of the main CPU which detects key scan, protection, etc. are displayed in % (100%: 5V).
All signal processing before this menu is executed will be held.
The keys on the main unit cannot be operated to detect the values of all keys in the K0/K1 and K2/RE pages. Turning
the rotary encoder (input selector on the main unit) will switch the submenu.
AD CHECK : FAN control based on detected temperature
With the voltage value detected from the temperature detection
circuit read as a temperature data by the A/D function of the
microprocessor, the FAN speed is controlled in 3 levels based
on that data.

[Note]
IEC958: Standard to identify the PCM bit stream signal. Digital format error refers to a digital
signal with the sampling frequency undefined (neither 44.1k, 32k nor 48k). Since the
operation of each device cannot be assured at fs outside specifications, the sub-microprocessor handles this status as the forced analog mode (ignored even if decoding is OK from
the detection terminal level), and selects the signal from the analog input terminal. Since
the sub-microprocessor transmits 000B (analog) for STATUS#0 bits 4-6 to the main microprocessor, the main microprocessor visually operates in the same way as with digital
unlocking.

Blank output terminal
Function
Connection to GND (Digital system ground terminal)
Terminal to connect the crystal of the crystal oscillator for internal synchronous
signal generation and a capacitor or to input an external clock. (2fsc or 4fsc)
Switching terminal between the mode to input a clock externally and the mode
for crystal oscillation. [L] = Crystal oscillation, [H] = External clock input
Terminal to output the blank signal (character and bordering OR signal) (MOD0 :
complex synchronous signal output at [H]). When resetting (RST terminal = [L]),
a crystal oscillation clock is output (but not when resetting by the command).
LC oscillation terminal
Terminal to connect the coil of the oscillator for character output dot clock
generation and a capacitor.
Character output terminal Terminal to output a character signal (MOD0 : It becomes an output terminal to
judge the external synchronous signal at [H] and outputs the result after judging
existence of the external synchronous signal. When a synchronous signal exists,
[H] is output.) When resetting (RST terminal = [L]), a dot clock (LC oscillation) is
output (but it is not output when reset by the command.)
Enable input terminal
Serial data input enable input terminal. The serial data input becomes enable at
[L]. A pull-up resistor is built in (hysteresis input).
Clock input terminal
Input terminal of clock for serial data input.
A pull-up resistor is built in (hysteresis input).
Data input terminal
Serial data input terminal. A pull-up resistor is built in (hysteresis input).
Power supply terminal
Power supply terminal for complex image signal level adjustment (Power supply
for analog system)
Video signal output terminal Output terminal for complex image signal.
Connected to GND or unconnected.
Video signal input terminal
Input terminal for complex image signal.
Power supply terminal
Power supply terminal (+5V : power supply for digital system)
Synchronous separation
Video signal input terminal of the built-in synchronous separation circuit (When
circuit input terminal
the built-in synchronous separation circuit is not used, it becomes a horizontal
synchronous signal input or a complex synchronous signal input.)
Synchronous separation
Terminal to monitor built-in synchronous separation circuit bias voltage.
circuit bias voltage terminal
Complex synchronous
Terminal to output a complex synchronous signal of built-in synchronous
signal output terminal
separation circuit ([H] when internally synchronized at MOD1 : [H], [L] output
when externally synchronized) (When the built-in synchronous separation circuit
is not used, SYNIN input signal is output.)
Vertical synchronous
Terminal to input a vertical synchronous signal by integrating the output signal of
signal input terminal
SEPOUT terminal. Connect the integration circuit between SEPOUT terminals.
Fix it to VDD1 when not used.
NTSC/PAL-M switching
Pin setting has a priority over switching of NTSC/PAL/PAL-M/PAL-N method.
input terminal
The NTSC method is selected after [L]= reset.
NTSC/PAL/PAL-M/PAL-N method setting by a command is effective.
[H] = PAL-M method.
SEPIN input control terminal Terminal to control whether or not to input VSYNC signal into SEPIN input
terminal. [L] = VSYNC inputted, [H] = VSYNC not inputted.
System reset input terminal. A pull-up resistor is built in (hysteresis input).
Reset input terminal
Power supply terminal (+5V) Power supply terminal (+5V : power supply for digital system)
