SAFETY CHECK-OUT

(US Model only)

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

1. Check the area of your repair for unsoldered or

poorly-soldered connections. Check the entire board surface for solder splashes and bridges.

2. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors.

3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators.

4. Look for unauthorized replacement parts, particularly transistors. that were installed during a previous repair. Point them out to the customer and recommend their replacement.

5. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement.

6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer.

7. Check the B+ and HV to see if they are at the

values specified. Make sure your instruments are accurate; be suspicious of your HV meter if sets always have low HV.

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

To Exposed Metal Parts on Set

0.15µF 1.Skil

voltmeter

(0.75V)

-= Earth Ground

Fig. A. Using an AC voltmeter to check AC leakage.

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.SmA (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 manufactures' 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 VOM or battery-operated AC voltmeter. The "limit" indication is 0. 7 5V. so analog meters must have an accurate lowvoltage 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)

HOW TO FIND A GOOD EARTH GROUND

A cold-water pipe is guaranteed earth ground; the

cover-plate retaining screw on most AC outlet boxes is also at earth ground. If the retaining screw is to be used as your earth-ground, verify that it is at ground by measuring the resistance between it and a coldwater pipe with an ohmmeter. The reading should be

zero ohms. If a cold-water pipe is not accessible,

connect a 60-100 watts trouble light (not a neon

lamp) between the hot side of the receptacle and the retaining screw. Try both slots, if necessary. to locate the hot side of the line, the lamp should light at normal brilliance if the screw is at ground potential. (See Fig. B)

GENERAL

The operating instructions mentioned here are partial abstracts from the Operating Instruction Manual. The page numbers of the Operating Instruction Manual remain as in the manual.

Features

Picture

HR (High Resolution) Trinitron

picture tube for PVM-14M4U/14M4E/20M4U/20M4E HR Trinitron tube provides a high resolution picture. Horizontal resolution is more than 800 TV lines at the center of the picture.

Trinitron'' picture tube for PVM-14M2U/14M2E/20M2U/20M2E Trinitron tube provides a high resolution picture. Horizontal resolution is more than 600 TV lines at the center of the picture.

Comb filter When NTSC video signals are received, a comb filter activates to make more accurate Y/C separation. This contributes to less of a decrease in resolution, cross color and cross luminance phenomena.

Beam current feedback circuit

The built-in beam current feedback circuit assures stable white balan~e.

Four color system available The monitor can display NTSC, PAL, SECAM and NTSCw

signals. The appropriate color system is

selected automatically.

Blue only mode In the blue only mode, an apparent monochrome display is obtained with all three cathodes driven with a blue signal. This facilitates color saturation and phase adjustments and observation of VCR noise.

1) 'Trinilron" is a registered trademark of Sony Corporation.

Input

Analog RGB/component input connectors Analog RGB or component (Y, R-Y and B-Y) signals from video equipment can be input through these

connectors.

Y/C input connectors The video signal, split into the chrominance signal (C) and the luminance signal (Y), can be input through this connector, eliminating the interference between the two signals, which tends to occur in a composite video signal, ensuring video quality.

External sync input When the EXT SYNC selector is in the on position, the monitor can be operated on the sync signal supplied from an external sync generator.

Automatic termination

(connector with J\/1,- mark only) The input connector is terminated al 75 ohms inside when no cable is connected to the loop-through output connector. When a cable is connected to an output connector, the 75-ohm termination is automatically released.

2) The NTSCu, system refers to an NTSC color system in which the subcarrier frequency is modified to 4.43MHz. When an NTSC recorded video program is played back with a Trident (PAUSECAMJNTSC. o) VTR, the NTSC..o signal is

oulput.

Functions

Underscan mode The signal normally scanned outside of the screen can

be monitored in the underscan mode.

11111111

When the monitor is in the underscan mode, the dark RGB scanning lines may appear on the top edge of the screen. These are caused by an internal test signal, rather than the input signal.

Horizontal/vertical delay mode The horizontal and vertical sync signals can be checked simultaneously in the HIV delay mode.

Auto/manual degaussing Degaussing of the screen can be performed automatically when the power is turned on, or manually by pressing the DEGAUSS bulton.

On-screen menus You can set color temperature, CHROMA SET UP, and other settings by using the on-screen menus.

Five menu languages You can select the menu language from among five languages on the menu.

EIA standard 19-inch rack mounting By using an MB-502B mounting bracket (for a 14-inch monitor, not supplied) or SLR-I 03A slide rail (for a 20-inch monitor, not supplied), the monitor can be mounted in an EIA standard 19-inch rack.

For details on mounting, refer to the instruction manuals supplied with the mounting bracket kit or slide rail kit.

SDI (Serial Digital Interface) Kit By using the following optional SDI Kits, the monitor can display SMPTE 259M 4:2:2 serial digital signal from a digital VCR. (ex. Sony 4:2:2 VCR)

-BKM-IOIC: Component SDI Kit (for video)

- BKM-102: Component SDI Kit (for audio)

IE!I

When the serial number of the BKM-IOIC you want to connect is less than 2,010,000, an optional connecting harness (part no. 1-900-230-35) will be required.

Serial Remote Interface Kit By using the optional BKM-103 Serial Remote Interface Kit, the monitor can be controlled from personal computers via the RS-422A serial interface.
