SERVICE SAFETY AND MAINTENANCE

WARNING:

BEFORE EXAMINING AND SERVICING

THIS CHASSIS READ CAREFULLY THE

FOLLOWING SAFETY

INSTRUCTIONS.

X-RAY RADIATION PRECAUTION

1. The EHT must be checked every time the TV is serviced to ensure that the CRT does

not emit X-ray radiation as result of excessive EHT voltage. The maximum EHT voltage permissible in any operating circumstances must not exceed the rated value. When checking the EHT, use the High Voltage Check procedure in this manual using an accurate EHT voltmeter.

2. The only source of X-RAY radiation in this TV is the CRT. The TV minimizes X-RAY

radiation, which ensures safety during normal operation. To prevent X-ray radiation, the replacement CRT must be identical to the original fitted as specified in the parts list.

3. Some components used in this TV have safety related characteristics preventing the

CRT from emitting X-ray radiation. For continued safety, replacement component should be made after referring the PRODUCT SAFETY NOTICE below.

4. Service and adjustment of the TV may result in changes in the nominal EHT voltage of

the CRT anode. So ensure that the maximum EHT voltage does not exceed the rated value after service and adjustment.

1.3 White Balance Adjustment

Generally, white balance adjustment is made with professional equipment. It’s not practical to

get good white balance only through manual adjustment. For TVs with I2C bus control,

change the bus data to adjust white balance.

2 CIRCUIT ADJUSTMENTS Preparation:

Circuit adjustments should be made only after completion of set-up adjustments.

Circuit adjustments can be performed using the adjustable components inside the TV set.

For TVs with 2 I C bus control, first change the bus data.

2.1 Degaussing

A degaussing coil is built inside the TV set. Each time the TV is powered on, the

degaussing coil

will automatically degauss the TV. If the TV is magnetized by external strong magnetic field,

causing color spot on the screen, use a specific degausser to demagnetize the TV in the

following ways. Otherwise, color distortion will be shown on the screen.

•Power on the TV set and operate it for at least 15 minutes.

•Receive red full-field pattern.

•Power on the specific degausser and face it to the TV screen.

•Turn on the degausser. Slowly move it around the screen and slowly take it away

from the TV

.•Repeat the above steps until the TV is degaussed completely.

2.2 Confirmation and Adjustment for Voltage Caution: +B voltage has close relation to high voltage. To prevent X-ray radiation, set +B

voltage to the rated value

•Make sure that the supply voltage is within the range of the rated value.

•Connect a digital voltmeter to the voltage output terminal of the main PCB. Power on the

TV and set the brightness and sub-brightness to minimum. Ensure that the voltage from

the main PCB reads as follows.

•Regulate voltage adjustment components on the power section until the +B the voltage

reaches the rated value.

2 TFA9842AJ

2-channel audio amplifier with volume control (SE: 1 W to 7.5 W)

2.1 General description

The TFA9842AJ contains two identical audio power amplifiers. The TFA9842AJ can be

used as two Single-Ended (SE) channels with a volume control. The maximum gain is 26 dB.

The TFA9842AJ comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The TFA9842AJ

contains a unique protection circuit that is solely based on multiple temperature

measurements inside the chip. This gives maximum output power for all supply voltages

and load conditions with no unnecessary audio holes. Almost any supply voltage and load

impedance combination can be made as long as thermal boundary conditions (number of

channels used, external heatsink and ambient temperature) allow it.

2.2 Features

2 Channel SE: 1 W to 7.5 W operation possibility

Soft clipping

Input clamps

Volume control Standby and mute mode

No on/off switching plops

Low standby current

High supply voltage ripple rejection

Outputs short-circuit protected to ground, supply and across the load

3 VERTICAL SCAN OUTPUT STAGE CIRCUIT TDA4863AJ/TDA4864A J

4.3.1 FEATURES

TDA4863AJ:Output current up to 3 A (p-p)

TDA4864AJ: Output current up to 2.5A (p-p)

3.2 GENERAL DESCRIPTION

The TDA4863AJ and TDA4864AJ are deflection boosters for use in vertical deflection

systems for frame frequencies up to 200 Hz.

The TDA4863AJ or TDA4864AJ needs a separate flyback supply voltage, so the supply

voltages are independently adjustable to optimize power consumption and flyback time.

For the TDA4863AJ or TA4864AJ the flyback supply voltage will be generated internally

by doubling the supply voltage and therefore a separate flyback supply voltage is not

needed.
