Color bars appear in the monitor or viewfinder. 3 With a pen or other sharp implement, press the AUTO LEVEL switch.

The auto level adjustment is necessary to ensure that the video levels are appropriate. Carry out auto level adjustment in step 6 (page 16) of the procedure under "Fitting and Adjustment".

After a few seconds, when the AUTO LEVEL indicator lights in green the auto level adjustment is completed.

Notes

If the indicator lights in red, check the switch setting on the board. (See step 1 on page 14.) If the indicator flashes, check that color bars are being displayed. The adjustment values are stored on this board, so readjustment is not normally required. However, if the CCU-TX7/TX7P is not used for a long time (several months), or if the board is installed in a different CCU-TX7/TX7P, the auto level adjustment must be made again.

3-3. CIRCUIT DESCRIPTION

CT-181 board

CT-181 board employs RF system circuit that is consists of RETURN VIDEO modulation circuit and PROMPT VIDEO modulation circuit (It becomes AUX VIDEO demodulation circuit by switching.) and microcomputer system circuit that controls the system.

Microcomputer system circuit section : The program is written in the ROM (IC1022) that is inserted to socket (CNI 1). ROM of built-in microcomputer is not used. Input and output of control signals between each board in CCU (included in COU) and each board are performed by serial data of 16 bit via I/O EXPANDER (IC1028). There are four communication channels with outside. The SCI-1 and SCI-2 built-in microcomputer communicate with CA (via modulation and demodulation circuit ) and RCP (via RS-232C driver). The external SCI (IC1024 and 1025) communicates with command link (RS-232C-1 and RS-232C-2 on the rear panel).

The RF system circuit section : RETURN VIDEO modulation circuit frequency-modulates the input signal (VBS) from RETURN VIDEO 1 or 2, and sends to the CA. Change of RETURN VIDEO 1 or 2 is switched by RETURN 1 and 2 changing switch on the CA. The PROMPT VIDEO modulation circuit amplitude- modulates the input signal (VBS) from PROMPT VIDEO on the rear panel, and sends to the CA. The PROMPT VIDEO modulation circuit becomes AUX VIDEO demodulation circuit by switching S2002 and connecting RF coaxial cable to CN3 and CN8. (It is needed to change on the YD-25 board of CA.) Demodulated AUX VIDEO is outputted from PROMPT VIDEO on the rear panel.

AA-90 board

This board demodulates the RF signal of MIC1, MIC2, INCOM, CAM DATA and TONE sent from the CA, modulates a PGM signal, the INCOM signal and control data send to the CA. And also, this board switches the INCOM line, and switches the input /output of each audio signals.

YD-26 board

YD-26 board demodulates Y, R-Y, B-Y, CAM SYNC and SKIN GATE. This circuit consists of cable length detection circuit, cable length compensation circuit and these demodulation circuits. The cable length detection detects from amplitude of Y modulated wave. In accordance with this, the cable compensation circuit compensates the amplitude and phase matching as cable length to modulated wave of Y or differential signal. After that, they are respectively demodulated in demodulator circuit.

ES-20 board

This board produces VBS and RGB signal from the Y, R-Y, and B-Y signals sent from the YD-26 board, switches these signals, and outputs them as WF and PIX signals. This board also generates each sync signal and color bars signal.

AU-234 board

This board inputs and outputs an INCOM signal on the front panel, displays tally signals, and turns on and off the power of camera.

IO-140 board

This board mixes the RF signal between CA and CCU with the power of the camera.

SDI-44 board (DXBK-701)

This board converts the analog video/audio signals into digital signals and outputs them as SDI signals.

Video signal processing : Y, R-Y and B-Y signals sent from the ES-20 board are converted from analog to digital and subject to the double over-sampling process on the digital filter IC308.

Audio signal processing : MIC1 and MIC2 signals sent from the AA-90 board are converted from analog to digital and subject to 64 times over-sampling process on IC904 and then subject to time- base compression on IC404.

These digital video signals and the time-base compressed digital audio signals are mixed on IC413. After that, the parallel data is converted to serial data on IC702 and output from this board.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer :

Check the metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.

LEAKAGE TEST

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. Leakage current can be measured by any one of three methods.

A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instruments.
A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.
Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. 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 2 V AC range are suitable. (See Fig. A)
