PRODUCT SAFETY GUIDELINES
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 noninsulated “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.
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 tilted 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.
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 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 compo­nents, 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 reassembly 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 ohms per volt or more sensitivity in the following manner: Connect a 1500 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 measurements 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.

OVERVIEW
Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test instrument.
Adjustments must be done in the correct order. The adjustment must be performed at 25±5 and 65±10% of relative humidity.
The input voltage of the receiver must maintain 110~240V, 50/60Hz while adjusting. Operate the receiver for about 15 minutes prior to the adjustment with 100% white pattern (06CH), or white condition in HEAT-RUN mode.
Enter into HEAT-RUN mode. Press the POWER ON KEY on R/C for adjustment. OSD display HEAT-RUN WHITE and screen display 100% full WHITE PATTERN. Set is activated HEAT-RUN without signal generator in this mode. Single color pattern of HEAT-RUN mode uses to check the PANEL (RED/BLUE/GREEN).
Caution: If you turn on a still screen more than 20 minutes,
an afterinage may occur in the black level part of the screen. (Especially Digital Cross Hatch Pattern), a afterimage may be occur in the black level part of the screen.
RGB AUTO CUT-OFF & MIN BIAS
1) If the PDP Module or Power Board was replaced, ad­just the Power PCB Assy Voltage prior to any other adjustment.
2) Input Full Back (0 Gray) signal which generated from Pattern Generator into Component input and RGB1 Input part.
3) Press POWER ON KEY on R/C for adjustment and select AUTO-CUT(Cut-off Auto Adjustment).
4) Press Vol. + key.
5) Screen adjustment starts with Full Black screen. Origi­nal Window screen will be presented about 5-6 sec­onds later. And if (OK OSD) appears on the screen, then the Auto Cut-off and Min-Bias adjustment will have been completed.

(5) After adjustment, press ¥ key to save adjustment and come out of the adjustment mode.
To check whether the circuit adjustment is operated well or not:
1) Display RGB1 to the Main picture, Component input to the Sub picture in the TWIN PICTURE.
2) To check the MIN-Bias, input Full Black (0 gray) sig­nal into Component input and RGB1 input part at the same time in the Pattern Generator.
3) To check the MAX-Bias, input Full White (255 gray) signal into Component input and RGB1 input part at the same time in the Pattern Generator.
4) Compare Black Level with White Level by eye. And if there is no Level difference, the adjustment is completed.
Data value, which adjusted in the board, is valid until the VSC Board is dissued and must be protected. For the protection of data, Micom does not permit any more adjustment after completion.
In case of re-adjustment, operate First Value Setting. Each PCB Assy must be checked by Check JIG Set before assembly. (Especially, be careful Power PCB Assy which can cause fatal Damage to PDP Module.)
