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. authorization, certification or recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.
IMPORTANT: The presentation or sale of this manual to any individual of firm does not constitute
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). you apply power to the unit.
IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before

WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food.

NO. 1 2 3 4 Name VSS1 XTAL IN Terminal name Ground terminal Crystal oscillation 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). 6 7 8 OSC IN OSC OUT CHARA Character output terminal Terminal to output a charactor 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). 9 /CS 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). 10 SCLK Clock input terminal Input terminal of clock for serial data input. A pull-up resistor is built in (hysteresis input). 11 12 SIN VDD2 Data input terminal Power supply terminal Srial data input terminal. A pull-up resistor is built in (hysteresis input). Power supply terminal for complex image signal level adjustment (Power supply for analog system) 13 14 15 16 17 CV OUT NC CV IN VDD1 SYN IN Video signal input terminal Power supply terminal Synchronous separation circuit input terminal Video signal output terminal Output terminal for complex image signal. Connected GND or unconnected. Input terminal for complex image signal. Power supply terminal (+5V : power supply for digital system) Video signal input terminal of the built-in synchronous separation circuit (When the built0in synchronous separation circuit is not used, it becomes a horizontal synchronous signal input or a complex synchronous signal input.) 18 SEP C Synchronous separation circuit bias voltage terminal 19 SEP OUT Complex synchronous signal output terminal Terminal to output a complex synchronous signal of built-in synchronous separation circuit [H] when internally synchronized at MOD1 : [H], [L] output when externally syncheonized) (When the built-in synchronous separation circuit is not used, SYNIN input signal is output.) 20 SEP IN Vertical synchronous signal input terminal Terminal to input a vertical synchronous signal by integrating the output signal of SEPOUT terminal. Connect the integration circuit between SEPOUT terminals. Fix it to VDD1 when not used. 21 CTRL2 NTSC/PAL-M switching input terminal Pin setting has a priority over switching of NTSC/PAL/PAL-M/PAL-N method. 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. 22 CTRL3 SEPIN input control terminal 23 24 /RST VDD1 Reset input terminal Power supply terminal (+5V) Terminal to control whether or not to input VSYNC signal into SEPIN input terminal. [L] = VSYNC not inputted. System reset input terminal. A pull-up resistor is built in (hysteresis input). Power supply terminal (+5V : power supply for digital system) Terminal to monitor built-in synchronous separation circuit bias voltage. LC oscillation terminal Terminal to connect the coil of the oscillator character output dot clock generator and capacitor.
