Introduction
Overview
This course will cover the new BA-6 chassis. The USA model sizes for the BA-6 chassis are 13", 20" and 24".
This chassis has major circuit changes from the BA-5 chassis, the main one being the integration of Syscon, YC
Jungle and Comb Filter into one IC package (called One-Chip). Other changes are in the Power Supply (Main
and Standby) and the Audio section. The Vertical and Horizontal deflection section are similar to previous
chassis’sexceptfortheHorizontalOutputtransistor,whichisanewdesign. Althoughthissinglechipdesignmay
seem to eliminate a large portion of circuit troubleshooting, there are still discreet circuits and external ICs that
can fail. In addition, when the unit becomes defective, a good understanding of the One-Chip IC functions will be
needed to determine if the problem is in the One-Chip IC or in external circuits.
CTV-30 Objectives
•Cover features of the BA-6 chassis.
•Define the One-Chip design.
•Provide a Theory of Operations (Waveforms and Voltages) and Troubleshooting Tips for each major
section of the BA-6 chassis.
•Discuss unit Self-Diagnostic functions and how they can assist in troubleshooting.

Auto Mute – A feature designed to automatically mute the TV audio when no RF signal is received
BBE – Shifts the phase of the audio signal to improve TV sound.
MTS – Allows direct access to the Multi-Channel TV Sound: Stereo, Mono or Auto SAP (Second Audio
Program) with a touch of a button.
Simulated Stereo – Simulates stereo quality sound for mono programs.
Speaker Box – A speaker enclosure used to improve sound quality.
SRS – Produces a dynamic three-dimensional sound for stereo audio signals (surround sound virtual

1. Features
Steady Sound – Stabilizes volume during sudden sound fluctuations of received audio.
WOW – Provides a dramatic presence with full, deep bass sound. When WOW is enabled, BBE is
directly activated to further enhance the audio program.
Video 3D comb Filter – Looks at the horizontal line above and below the line being processed, along with the
same three lines in the frame before and after, to optimally remove the chroma component from the Y in
a composite video signal. This reduces dot crawl and other noise to produce the best picture possible.
V-Chip – (Parental Control) Allows parental control over rated television programs.
VM – (Velocity Modulation) Sharpens the picture definition by varying the beam-scanning rate to give
every object a sharp, clean edge.
XDS/CC –Information services thatsomebroadcasters are adding totheirsignals, including time,station
call letters and programming information.
YUV – (Component Video) Delivers optimum picture quality by supplying separate connections for the
luminance (Y) and color information (UV).

Overview
The BA-6 chassis has taken a major step towards the “TV on a Chip” concept. The One Chip (IC001) performs
all System Control and Signal Processing functions. In previous models these functions were handled by three
different ICs: System Control, YC Jungle and Comb Filter. A direct result of the higher circuit integration is the
lower PCB count. The number PCBs went from five in the BA-5 to only two in the BA-6 chassis (as illustrated in
Figure 2-1).

circuits.

2. Overall BA-6 Block
System Control
All system control functions are performed by IC001 (OneChip). The main operating crystal is X001 (8MHz).
The following control functions are handled by IC001:
1) Remote commands (SIRSC) decoding
2) Main Converter Power Supply ON/OFF
3) Audio IC Input switching (commands ONLY)
4) Audio Muting and Volume Control
5) Video Input Switching (Performed Inside IC001)
6) DegaussON/OFF
7) Tuner Control and Muting
PowerSupply
The Standby Power Supply on the BA-6 is Energy Star® compliant. It supplies Standby 5V and Standby 3.3V to
keep various circuits on the A board active in Standby Mode. The Main Converter Power Supply supplies the rest
of the voltages (+135V, 14V, 9V, Main 3.3V) to the A board when an ON command is received..
Audio Section
The A board contains audio switching, processing (both of these functions are performed in IC400 for the
appropriate models) and amplifier circuits. The only circuit change on the A board between models is the Audio
processing IC. The KV-20FV100, and KV-24FV300 use IC400 (IC400 contains the Surround Sound processing
circuits); the KV-20FS100, KV-24FS100, and KV-13FS100/110 use IC401. All models use Audio Amplifier IC404.
Video Section
All Front/Rear Video input jacks and the Tuner are located on the A board. All video switching and processing is
performed by the ONE-Chip (IC001) on the A board. New on the BA-6 chassis is the addition of a component
(YUV) jack on the rear of the unit. Crystal X301 (6MHz) is used for NTSC signal (Composite) color signal
processing. If X301 is defective, the unit will still operate normally, except the picture will be in Black and White.
Deflection
The Horizontal, Vertical and Pincushion correction circuits are all on the A board. These circuits, along with the
Fly-back transformer, drive the CRT electron beam for picture scanning. The Horizontal output transistor is new
on the BA-6 chassis for better performance.
The Degauss circuit and relay is also on the A board.
CV Board
The CV board connects to the neck of the CRT via J1751. The circuits found on this PCB are the RGB amplifier
and buffer transistors and Output Drive IC (IC1751), N/S Amplifier and VM Drive circuit. The N/S amplifier and
coil are used to rotate the trace for good level horizontal scanning (Tilt Correction). The VM (Velocity Modulation)
circuit assists in sharpening the image when transitioning from Black to White and visa-versa.

PowerSupplyBlock
The power supply section in the BA-6 chassis is labeled Energy Star® compliant. This means that the power
supply meets or exceeds the power conservation standard set forth by the EPA and the Department of Energy.
That standard states that an analog TV should draw <1 Watt in Standby Mode. For more information on Energy
Star, go to www.energystar.gov. The power supply section consists of the 5V Standby Supply and the Main
Converter Switching Supply (ref. Figure 3-1). Also included in this diagram is the Degauss circuit.
5VStandbyPowerSupply
The Standby Power supply in the BA-6 chassis is a Conventional Full-wave rectifier, capacitor filtered type. This
isa departure from previousmodels,whichuse switch-mode power suppliesinthestandby circuit. The AC input
to the Standby supply is connected directly across the ACIN source, before the AC input relay RY600. So, the
Standby Power supply outputs the voltages listed on Figure 3-1 once AC is applied to the set.
Main Switching Power Supply
As in previous models, the Main Switching supply is a switch-mode power supply. The Main supply receives AC
input through relay RY600 after System Control receives an ON command. Once the switching oscillations
begin and feedback (through IC604) is established, the Main Power outputs the voltages listed in Figure 3-1.
