The LCD panel is manufactured to provide many years of useful life.

Occasionally a few non active pixels may appear as a tiny spec of color.

This is not to be considered a defect in the LCD screen.

ELECTRICAL ADJUSTMENT INSTRUCTIONS

General Note: “CBA” is abbreviation for
“Circuit Board Assembly.”

Note: Electrical adjustments are required after

replacing circuit components and certain
mechanical parts. It is important to perform
these adjustments only after all repairs and
replacements have been completed.
Also, do not attempt these adjustments unless
the proper equipment is available.

Test Equipment Required

1. Remote control unit

2. Color Analyzer,
CA-310 (KONICA MINOLTA Luminance meter) or
measuring instrument as good as CA-310.

3. LED32-H9000M (2010 Model)

4. LVDS WIRE (Custom-Made)

How to set up the service mode:

Service mode:

1. Turn the power on.

2. Press [SOURCE], [2], [5], [8] and [0] buttons on
the remote control unit in this order to enter the
service mode. The Factory Setting menu appears
in the screen.

Example:

1-2 LC10P(A23FAEP)EA

1. VCOM Adjustment

Preparation:

Change the Panel Code of the LED32-H9000M from
140 to 117 since the LVDS Format of LED32-H900M
is “JEIDA” and LVDS Format of 32FL552/10 is
“VESA”.

Procedure:

1. Connect the connector (LVDS OUT) on the Digital
Main CBA Unit of the LED32-H9000M (2010
Model) to the connector (LVDS IN) on the T-CON
CBA of 32FL552/10 with long LVDS wire.

2. Set the color analyzer at the zero point calibration
and bring the optical receptor pointing at the
center of the LCD-Panel of this LCD TV.
Note: The optical receptor must be set
perpendicularly to the LCD Panel surface.

3. Turn on the power of LED32-H9000M.

4. Turn on the power of 32FL552/10.

5. Enter the service mode through LED32-H9000M.

6. Enter the service mode through 32FL552/10 and
press [2] button on the remote control unit. The
Flicker pattern appears in the screen.
Adjust the variable resistor on the T-CON CBA so
that the color analyzer value becomes minimum.

7. To cancel or to exit from the VCOM Adjustment,
press [BACK] button.

SCHEMATIC DIAGRAMS / CBA AND TEST POINTS

Standard Notes

WARNING

Many electrical and mechanical parts in this chassis
have special characteristics. These characteristics
often pass unnoticed and the protection afforded by
them cannot necessarily be obtained by using
replacement components rated for higher voltage,
wattage, etc. Replacement parts that have these
special safety characteristics are identified in this
manual and its supplements; electrical components
having such features are identified by the mark “!” in
the schematic diagram and the par ts list. Before
replacing any of these components, read the parts list
in this manual carefully. The use of substitute
replacement parts that do not have the same safety
characteristics as specified in the parts list may create
shock, fire, or other hazards.

Notes:

1. Do not use the part number shown on these
drawings for ordering. The correct part number is
shown in the parts list, and may be slightly
different or amended since these drawings were
prepared.

2. All resistance values are indicated in ohms
(K = 10

3

, M = 106).

3. Resistor wattages are 1/4W or 1/6W unless
otherwise specified.

4. All capacitance values are indicated in µF
(P = 10

-6

µF).

5. All voltages are DC voltages unless otherwise
specified.

6. Electrical parts such as capacitors, connectors,
diodes, IC’s, transistors, resistors, switches, and
fuses are identified by four digits. The first two
digits are not shown for each component. In each
block of the diagram, there is a note such as
shown below to indicate these abbreviated two
digits.

LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC DIAGRAMS ON
THE FOLLOWING PAGES:

1. CAUTION:

FOR CONTINUED PROTECTION AGAINST FIRE HAZARD, REPLACE ONLY WITH THE SAME TYPE
FUSE.

2. CAUTION:

Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit.

If Main Fuse (F101) is blown, first check to see that all components in the power supply circuit are not
defective before you connect the AC plug to the AC power supply. Otherwise it may cause some components
in the power supply circuit to fail.

3. Note:

1. Do not use the part number shown on the drawings for ordering. The correct part number is shown in the
parts list, and may be slightly different or amended since the drawings were prepared.

2. To maintain original function and reliability of repaired units, use only original replacement parts which are
listed with their part numbers in the parts list section of the service manual.

4. Voltage indications on the schematics are as shown below:

Plug the TV power cord into a standard AC outlet.:

NOTE:

The voltage for parts in hot circuit is measured using
hot GND as a common terminal.

CAUTION !

Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F101) is blown , check to see that all components in the power supply
circuit are not defective before you connect the AC plug to the AC power supply.
Otherwise it may cause some components in the power supply circuit to fail.

CAUTION !

For continued protection against fire hazard,
replace only with the same type fuse.

Digital Main 6 Schematic Diagram

The order of pins shown in this diagram is different from that of actual U7.
U7 is divided into six and shown as U7 (1/6) ~ U7 (6/6) in this Digital Main Schematic Diagram Section.

1 NOTE:

2-11

Power Supply CBA Top View

Because a hot chassis ground is present in the power supply
circuit, an isolation transformer must be used when repairing.
Also, in order to have the ability to increase the input slowly,
when troubleshooting this type of power supply circuit,
a variable isolation transformer is required.

NOTE:

The voltage for parts in hot circuit is measured using
hot GND as a common terminal.

CAUTION !

Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F101) is blown , check to see that all components in the power supply
circuit are not defective before you connect the AC plug to the AC power supply.
Otherwise it may cause some components in the power supply circuit to fail.

CAUTION !

For continued protection against fire hazard,
replace only with the same type fuse.
