Descripción del SHARP Z830 Manual de Servicio

Manual de servicio completo en formato digital (archivo PDF). Los manuales de servicio por lo general contienen diagramas de circuitos, tarjetas de circuitos impresos, consejos para reparación, diagramas de cableado, diagramas de bloque y lista de refacciones. El Manual de Servicio (a veces llamado Manual de Reparación) es usado principalmente por los técnicos.

Si tan solo quiere saber cómo utilizar su televisión, reproductor de vídeo, reproductor de mp3, etc. Quizá lo que necesita es el Manual del Propietario. Después de colocar la orden le enviaremos las instrucciones de descarga a su dirección de e-mail.

The shorter the pulse ON time is, the higher the CLV is, and vice versa. The pulse ON time rises at the zero-cross timing of AC and is driven with duty. Positive pulses the copy lamp ON signal are generated by C248 (C253) at falling of the CPU output and inputted to the photo triac through the 2-stage transistors.

(11) Power section
This model is provided with the auto shut-off mode. The power section is also designed for it. When the power switch of the copier is turned on and the AC power is supplied, AC waveforms for +5V power are generated in the secondary side of transformer T301. The AC waveforms are full-wave-rectified and smoothed by diode BD102 on the main PWB side, and 5V is generated by 3-terminal regulator of IC111. The 5V power is supplied to the CPU. When the CPU is actuated by the 5V power, it starts the switching power to output the SWPEN signal (CPU output: LOW). The switching power outputs voltages of 24V and VBS with this signal. BVS is stabilized by IC112 to become a voltage with stable BV, and is used for LED display. 24V is supplied to the motor and the solenoid, and supplied also to the 3-terminal power for 5V through D144. When the CPU turns off SWPEN to enter the auto power shut-off mode, 24V and VBS output falls near zero, virtually turning off.

* At rising of the CLPWM signal (V4), the coy lamp is switched by the triac. The trigger signal Cl is sent to the triac to turn on the lamp. Then the lamp is turned off at the zero-cross point of V1 waveform. The CPU reads the control voltage level (QV) corresponding to the change in the copy lamp voltage The CLV produces the waveform equivalent to the copy lamp voltage waveform which disables the full-rectified waveform of AC input during the pulse ON time. The waveform is converted to the DC level by the low pass filter composed of C102 and R105, and inputted to the CPU. The relationship between the CLV and the pulse ON time is shown in the figure below.
