PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS

IMPORTANT SAFETY NOTICE

This Manual was prepared for use only by properly trained audio-visual service technicians.

When servicing this product, under no circumstances should the original design be modified or altered without permission from Zenith Electronics Corporation. All components should be replaced only with types identical to those in the original circuit and their physical location, wiring and lead dress must conform to original layout upon completion of repairs.

Special components are also used to prevent x-radiation, shock and fire hazard. These components are indicated by the letter “x” included in their component designators and are required to maintain safe performance. No deviations are allowed without prior approval by Zenith Electronics Corporation.

Circuit diagrams may occasionally differ from the actual circuit used. This way, implementation of the latest safety and performance improvement changes into the set is not delayed until the new service literature is printed.

Caution: Do not attempt to modify this product in any way. Never perform customized installations without manufacturer’s approval. Unauthorized modifications will not only void the warranty, but may lead to property damage or user injury.

Service work should be performed only after you are thoroughly familiar with these safety checks and servicing guidelines.

GRAPHIC SYMBOLS

The exclamation point within an equilateral triangle is intended to alert the service personnel to important safety information in the service literature.

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the service personnel to the presence of non-insulated “dangerous voltage” that may be of sufficient magnitude to constitute a risk of electric shock.

The pictorial representation of a fuse and its rating within an equilateral triangle is intended to convey to the service personnel the following fuse replacement caution notice:

CAUTION: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ALL FUSES WITH THE SAME TYPE AND RATING AS MARKED NEAR EACH FUSE.

SERVICE INFORMATION

While servicing, use an isolation transformer for protection from AC line shock. After the original service problem has been corrected, make a check of the

following:

FIRE AND SHOCK HAZARD

1. Be sure that all components are positioned to avoid a possibility of adjacent component shorts. This is especially important on items transported to and from the repair shop.

2. Verify that all protective devices as such as insulators, barriers, covers,

shields, strain reliefs, power supply cords, and other hardware have been reinstalled per the original design. Be sure that the safety purpose of the polarized line plug has not been defeated.

3. Soldering must be inspected to discover possible cold solder joints, solder splashes, or sharp solder points. Be certain to remove all loose foreign particles.

4. Check for physical evidence of damage or deterioration to parts and compo-

nents, for frayed leads or damaged insulation (including the AC cord), and replace if necessary.

5. No lead or component should touch a receiving tube or a resistor rated at 1 watt or more. Lead tension around protruding metal surfaces must be avoided.

6. After re-assembly of the set, always perform an AC leakage test on all exposed metallic parts of the cabinet (the channel selector knobs, antenna terminals, handle and screws) to be sure that set is safe to operate without danger of electrical shock. DO NOT USE A LINE ISOLATION TRANSFORMER DURING THIS TEST. Use an AC voltmeter having 5000 ohm, 10 watt resistor, paralleled by a .15 mfd 150V AC type capacitor between a known good earth ground (water pipe, conduit, etc.) and the exposed metallic parts, one at a time. Measure the AC voltage across the combination of 1500 ohm resistor and .15 mfd capacitor. Reverse the AC plug by using a non-polarized adaptor and repeat AC voltage measures for each exposed metallic part. Voltage measured must not exceed

0.75 volts RMS. This corresponds to 0.5 milliamp AC. Any value exceeding this limit constitutes a potential shock hazard and must be corrected immediately.

X-RADIATION

1.Be sure procedures and instructions to all service personnel cover the subject of x-radiation. The only potential source of x-rays in current TV receivers is the picture tube. However, this tube does not emit x-rays when the HV is at the factory-specified level. The proper value is given on the applicable schematic. Operation at higher voltages may cause a failure of the picture tube or high-voltage supply and, under certain circumstances, may produce radiation in excess of desirable levels.

2.Only factory-specified CRT anode connectors must be used.

3.It is essential that the service personnel have available an accurate and reliable

high-voltage meter

4.When the high-voltage circuitry is operating properly, there is no possibility

of an x-radiation problem. Every time a color chassis is serviced, the brightness should be run up and down while monitoring the high voltage with a meter, to be certain that the high voltage does not exceed the specified value and that it is regulating correctly.

5.When troubleshooting and making test measurements in a product with a problem of excessively high voltage, avoid being unnecessarily close the picture tube and the high voltage power supply. Do not operate the product longer than necessary to locate the cause of excessive voltage.

6.Refer to HV, B+, and shutdown adjustment procedures described in the

appropriate schematics and diagrams (where used).

IMPLOSION

1.All direct view picture tubes are equipped with an integral implosion protection system; take care to avoid damage during installation.

2.Use only the recommended factory replacement tubes.

TIPS ON PROPER INSTALLATION

1.Never install any receiver in a closed-in recess, cubbyhole, or closely fitting

shelf space over, or close to, a heat duct, or in the path of heated air flow.

2.Avoid conditions of high humidity such as: outdoor patio installations where dew is a factor, near steam radiators where steam leakage is a factor, etc.

3.Avoid placement where draperies may obstruct venting. The customer should also avoid the use of decorative scarves or other coverings that might obstruct ventilation.

4.Wall and shelf-mounted installations using a commercial mounting kit must follow the factory-approved mounting instructions. A product mounted to a shelf or platform must retain its original feet (or the equivalent thickness in spacers) to provide adequate air flow across the bottom. Bolts or screws used for fasteners must not touch any parts or wiring. Perform leakage tests on customized installations.

5.Caution customers against mounting a product on a sloping shelf or in a titled position, unless the receiver is properly secured.

6.A product on a roll-about cart should be stable in its mounting to the cart. Caution the customer on the hazards of trying to roll a cart with small casters across thresholds or deep pile carpets.

7.Caution customers against using a cart or stand that has not been listed by Underwriters Laboratories, Inc. for use with its specific model of television receiver or generically approved for use with TVs of the same or larger screen size

8.Caution customers against using extension cords. Explain that a forest of extensions, sprouting from a single outlet, can lead to disastrous consequences to home and family.

SR24 - 923-03508 CL - SAFETY

PRODUCT SAFETY SERVICING GUIDELINES FOR AUDIO-VIDEO PRODUCTS

X-RADIATION

To prevent possible exposure to radiation caused by excessive CRT Anode voltage, the CH/CL Chassis incorporates a “High Voltage Shutdown” circuit. This circuit senses the level of flyback pulse from the “Flyback Transformer” representative of the actual high voltage on the CRT anode. When this level exceeds a predetermined voltage, the circuit shuts down the horizontal drive, preventing further generation of anode voltage. In this condition, the horizontal drive is “latched” off for about 5 seconds, after which, restart is attempted.

SHUTDOWN CIRCUIT OPERATION

The flyback pulse voltage from Pin 6 of TX3201 (Flyback Transformer) is peak detected (rectified) by the action of diode D3000 and capacitor C3001. This forms a DC voltage appearing on C3001 representative of the CRT anode voltage (HV) produced by T3201. This voltage is divided down by precision resistors RX3001, RX3002, & RX3003. This lower voltage, appear on the positive input of IC3101.

If the CRT anode voltage becomes excessive, pin 5 of IC3101 will be higher than the negative input of pin 6. This will cause the output of pin 7 to rise to approximately 15 volts. This signal (SD_DRV) is sent to the base of Q4000 causing the Horizontal Drive to be disabled and latched, which causes the HV to shutdown. In about 5 seconds, the shutdown circuit resets (Pins 8, 9 & 14 of IC2900), the Horizontal Drive and HV will be reestablished. The circuit formed by Q3104, C3108, C3113, D3107, R3134, R3132, R3131, and R3133 disables the HV compensation output (Q3102-B signal) during turn on and shutdown conditions (transients).

CRT ANODE HIGH VOLTAGE MEASUREMENT PROCEDURE

Each CRT screen has its own safe operating Anode Voltage and shutdown voltage. Critical Safety components (designed with an ‘X’ in the component designator) are designed to operate the CRT at a safe operating Anode voltage and provide proper shutdown thresholds. If replacement of any of these components are deemed necessary, it is important to use original type Zenith replacement components.

After a replacement is made, confirm proper Anode voltage using the following procedure.

Measurement of the CRT Anode voltage must be performed with no visible raster on the screen and operating at nominal horizontal scanning frequency 37.9 khz (TV or SVGA signal).

After discharging the CRT, connect a high impedance high voltage meter to the CRT anode. Turn the television ‘On’ and confirm a good signal is being displayed. Reduce Brightness and Contrast settings until the picture is well extinguished. Observe the Anode voltage meter reading and compare with the table below for the proper CRT screen size. If the voltage reading is higher than the maximum, verify circuit component values and proper operation.

HV SHUTDOWN MEASUREMENT PROCEDURE

1. Adjust the beam current to OmA in NTSC mode.

2. Apply a variable DC voltage to pin 10 of the PDT1 connector, from 20 to 0 VDC, starting at 20 VDC.

3. Slowly decrease supply towards zero.

4. Remove DC voltage from pin 10 of PTD1.

5. After approximately 5 seconds, verify that the HV must be reestablished (High Voltage Reset).

OVERVIEW

INTERFACES

CAMPORT

Some models have video and right/left audio input jacks at the front of the receiver. These jacks can be used to view video tapes from a VCR or Camcorder. When the video cable is plugged into the jack, the shorting jumper J1 opens, placing a high at pin 10 of the IC6000 microprocessor. This switches the TV into the auxiliary mode. As long as the cables are attached, the TV set will be locked in auxiliary mode. Use of a remote control or buttons on the front of the set will not permit switching into tuner mode until the video cable is disconnected.

SUPERPORT - MPI

Zenith Commercial Product receivers are now being adapted to interact with other equipment. Prime examples of this can be found in Lodging and Health Care situations where the set is controlled from the main office.

All this is made possible by the new technology that is being built into these receivers. The SuperPort and Multiple Protocol Interface (MPI) jack and associated circuitry allow remote control of the set.

MULTIPLE PROTOCOL INTERFACE

Television functions and features are controlled by the communication of commands and status information through a Superport by the MPI interface.

EBC (EDGE BOARD CONNECTOR)

Allows easy access for removing/installing accessory modules providing a rail mounted slide-through card. These cards might contain one of the above features.

CONNECTION CENTER ON BACK OF TV

The connection on the back of the TV contains the input and output interfaces.

ZENITH ELECTRONICS CORPORATION, GLENVIEW, ILLINOIS USA

LT-2000 CLONE PROGRAMMER

The Quick Set II programmer LT2000 allows custom setup and programming information to be quickly copied from a master TV into multiple television sets. Once learned from the master, setup data is retained in the LT2000 for future use and recall.

When using the LT2000, operation will be easier if the TV is connected to a good quality signal and is displaying a stable picture. To operate the LT2000, use the indicated keys on an installer’s remote or user’s remote, or the front panel keys on the TV receiver.

SETUP

Begin the programming process by setting up a master TV set using one of the installer’s remotes or an MBR remote. Follow the instructions in the operating guide for the specific TV model. Remember to set all features that will be customized including the channel scan list, channel labels, and installer menu setups.

Next connect the LT2000 to the master TV set using the cable provided with the programmer. Connect the cable between the MPI jack on the TV and the programmer. The TV set automatically activates the programmer.

Once connected, check the “Status Indicator” LED on the programmer. If the indicator is green and flashing (a doubleblink “heartbeat” pattern), proceed to the next step.

Disconnect the LT2000 from the TV set when the desired task has been completed. Disconnecting the clone automatically switches it off. The real time clock continues to run when the main circuits are switched off.

After replacing exhausted batteries, or if the programmer behaves strangely after a static shock, use a paper clip or similar instrument inserted through the small hole marked “RESET” to activate the internal reset switch and restore normal operation. After reset, check the real-time clock setting. It may be necessary to reset the clock from a TV programmed to the correct time.

The specific microprocessor used in any TV set may be determined by activating the service menu. The microprocessor part number appears at the top of the screen with the service menu is activated. Processors before the 221-01006 have a limited screen display capability. They cannot display entire screens as shown in the quick setup instructions accompanying the LT2000 programmer. Use the printed menu illustrations on the quick setup sheet as an aid in making programming choices.

PARENTAL CONTROL

This optional feature can be used to prevent (block) unwanted programming from appearing on your TV.

PARENTAL CONTROL offers the user a wide variety of options and settings that restrict or block programming that can appear on the TV. PARENTAL CONTROL allows users the capability of defining which program ratings they consider acceptable to younger or more sensitive viewers.

USER MENUS

PARENTAL CONTROL can be preset and turned on or off by a user who specifies the 4 number password. The number of hours blocked must also be specified.

General audience and children viewer blocks can both be programmed into the TV’s memory. Viewer ratings are specified for both the TV industry and the motion picture industry; both rating systems can be used. The ratings are based mainly on children’s ages.

OVERVIEW

To ensure complete coverage for all TV programs (movies and regular TV shows), choose ratings from the Motion Picture Association of America (MPAA) Rating System chart and the TV Parental Guidelines Rating System chart (both shown on the next page). Use the AGE BLOCK option for General Audiences and for Children. You can also add additional restrictions from the CONTENT BLOCK menu.

Things to Consider before Setting Up Parental Control: Determine which ratings you consider acceptable for viewing. (For example, if you choose TV-PG, all of the more restrictive ratings will be blocked automatically: the viewer will not be able to see TV-PG, TV-14, or TV-MA rated programming.)

Select whether auxiliary video sources will be blocked in the AUX SOURCES block option. (Blocks signals from VCRs, DVD players, etc. connected to the TV Audio/Video input jacks). You could also leave AUX SOURCES unblocked, and then choose allowable ratings.

In the CONTENT BLK option, you can block program Content based on individual parameters such as Strong Dialog, Bad Language, Sex Scenes, Violence Scenes, or Fantasy Violence Scenes.

You can set PARENTAL CONTROL to be active in the SET HOURS option for up to 12 hours. Use the number keys on the remote to select a secret password in the SET PASSWORD option.

Don’t forget the password, as it is the only way you can access the PARENTAL CONTROL menu and change rating selections or turn PARENTAL CONTROL off.

If you do not want PARENTAL CONTROL to be active all the time, you can turn it on or off with the LOCK ON/OFF option.

Notes:

• You can set different PARENTAL CONTROL viewing restric-

tions for general audiences and for children - - both can be active at the same time.

• Simply specifying one content block such as Sex Scenes, will

not automatically block another type of content in the programs from appearing.

• Even if you choose to leave the AUX INPUTS unblocked, the

ratings you specify will automatically restrict the programming that appears from the video sources.

• You cannot disable PARENTAL CONTROL by disconnecting the

TV from power. Block hours will automatically reset to the original block time setting specified if power is disconnected.

• To reset the password, use the installer’s remote control to

deactivate the V-Chip in the Installer’s menu (#53). Exit out of the Installer’s Menu after deactivating the Parental Control. Then enter back in and reactivate the V-Chip.

With the PARENTAL CONTROL menu on-screen, use the Up Arrow to choose an option, such as CONTENT BLOCK. Use the Left/ Right arrow to show the CONTENT BLOCK menu, to adjust or set the rating for an option.

To block sex scenes, for example, use the “TV-PG and above” setting. To block dialog, use LEFT/RIGHT ADJ arrows to select among UNBLOCKED, TV-PG and above, or TV-14. (See the Ratings Charts for rating meanings.)

After you have selected and adjusted the PARENTAL CONTROL menu options to your preferences:

- Set the number of hours Parental Control will be on.

- Set a 4 number password.

- Set the Lock On/Off option to either on or off.
