PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in television receivers have special safety related characteristics. These character­istics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by
using replacement components rated for higher voltage, wattage, etc.

Replacement parts which have special safety characteristics are identified in this service manual.

The replacement for any safety part should be identical in value and characteristics.

SAFETY PRECAUTIONS

NOTICE: Observe all cautions and safety related notes located inside the receiver cabinet and on the

receiver chassis.

WARNING:

1. Operation of this receiver outside the cabinet or with the cover removed presents a shock hazard
from the receiver's power supplies. Work on the receiver should not be attempted by anyone who is
not thoroughly familiar with the precautions necessary when working on high voltage equipment.

2. Do not install, remove or handle the LCD panel in any manner unless shatterproof goggles are
worn. People not so equipped should be kept away while the panel is being handled. Keep
the panel away from the body while handling.

3. When service is required, observe the original lead dress. Where a short-circuit has occurred, replace
those components that indicate evidence of overheating.

Leakage current check

Before returning the receiver to the customer, leakage current should be measured using following methods.

1. Cold Check

With the alternating current (AC) plug removed from the AC source, place a jumper across the two AC plug prongs.

Connect one lead of an ohm meter to the AC plug and touch the other lead to each exposed met al part (i.e. anten­nas, handle bracket, metal cabinet, screw heads, metal overlay , control shafts, etc.), p articularly any exposed metal
part that has a return path to the chassis. The resistance of the exposed metal parts having a return path to the
chassis should be a minimum of 1Meg Ohm. Any resistance below this value indicates an abnormal condition
and requires corrective action.

2. Hot Check ...Use the circuit shown below to perform the hot check test.

1. Keep switch S1 open and connect the receiver to the measuring circuit. Immediately after

connection, and with the switching devices of the receiver in their operating positions, measure

the leakage current for both positions of switch S2.

2. Close switch S1, energizing the receiver . Immediately after closing switch S1, and with the

switching devices of the receiver in their operating positions, measure the leakage current for both
positions of switch S2. Repeat the current measurements of items 1 and 2 after the receiver has

reached thermal stabilization. The leakage current must not exceed 0.5 milliampere (mA).

MODELS: LT-3280D/LT-3780D

It explains the video circuits of LT-3780,LT-3280(Model name of display side only : LT-3780D,LT-3280D).
It corresponds to various inputs (PC, Monitor Link

TM

A/V Input).
It explains the composition and its function of an video circuit.
(Refer to an attached “Video block diagram of LT-3780D,LT-3280D”, regarding as the flow of video signal.)

1-1. Video input circuit of PC
In PC input, it is inputted into IC400 of the signal processing IC via Following IC

(A) IC203 : Analog-to-digital conversion IC (AD9888KSZ-170 : Analog devices)
The video signal (R, G, B) of PC input is changed into a digital signal (8 bits each) from an analog
signal. Moreover, by this IC, it has the function below besides digital conversion.

- Contrast adjustment for PC

- brightness adjustment for PC

This IC is controlled by register control of IC203 via

3.3V IIC-bus 3.3V IIC-bus

3.3V IIC-bus

3.3V IIC-bus 3.3V IIC-bus

to MPU(IC700)

(B) IC201 : Invert IC with the Schmidt trigger (74LCX14 : Fairchild)

It is IC which inputs the horizontal sync signal and vertical sync signal of PC input.
Since there are what has a bad rising and falling characteristic and what has low amplitude in the
sync signal outputted from PC, it is necessary to modify the waveform.
It corresponds to the above-mentioned waveform as follows by this IC.

- a bad rising and falling characteristic. : Rise-time and fall-time is carried out early.

- a waveform is noisy : It prevents that the mistaken pulse occurs by the Schmidt circuit.

- Low Amplitude : If voltage threshold is satisfied, high level will output in 3.3V.

Since 74LCX14 is a invert circuit, if its gate pass twice and it has united polarity.
(C) IC200 : 1K-bit EEPROM (24LC21ATI : Microchip)
This is the IC for EDID of PC.
This IC has important information about PC input such as product code, serial number, video
specification, proposed timing, color information etc.
(D)IC202 : AND-circuit IC (SN74LVC08APWR : Texas Instruments)
This IC is to disable the H, V sync signal line connected to IC which power supply is dropped while
stand-by. It can operate correctly by using this.
This is controlled by ENABLE singnal from MPU(IC700) ( L : disable)
(E)IC204 : D Flop-Flop IC(TC74VCX74FT : TOSHIBA)
The role of this IC is to synchronize H sync signal and V sync signal.
For output signal of IC203, H sync is synchronized by dot-clock from IC203, but V sync is not
Synchronized by H sync. This IC uses to be operated without miss-operation.

(F)IC2A0 : Color conversion IC(M66471FP : Mitsubishi)
This IC uses to perform Color conversion function such as PerfectColor, Colorview.
(G)IC2A1 : TMDS-Transmitter IC(SII160CTG100 : SiliconImage)
This IC uses to convert signal’s specification from TTL to TMDS (differential signal).
Since the input port of latter IC (IC400: Signal processor ) could use only the TMDS input, this input
specification was united by this IC.

Page 27

MODELS: LT-3280D/LT-3780D

1-2. Video input circuit of Monitor LinkTM A/V Input
In Monitor Link

TM

A/V Input, it is inputted into IC400 of the signal processing IC via Following IC.

(H)IC500 : HDMI-Receiver IC ((SII9993CTG100 : SiliconImage)

This IC uses to receive and correspond the differential signal. This IC corresponds not only HDMI

input but also DVI input(TMDS interface) . Supported timing of this input is 480P/1080i/720P.
The output format of this IC is YCbCr4:4:4, not RGB.
(I) IC501 : 2K-bit EEPROM (24LC22ATI : Microchip)

TM

This is the IC for E-EDID of Monitor Link
This IC has important information about Monitor Link

A/V Input.

TM

A/V Input such as audio, speaker,

Identification code, in addition to product code, serial number, video specification, proposed timing,

color information.
