Firmware Update Procedure
User Upgrade (Filename example: TVNB012_00_UF_XX91_AA.ecc)
Upgrade the firmware only. The setting values will not be initialized.
The User Upgrade and the Firmware Upgrade (Factory Upgrade) will be done by the same file. If you want to upgrade the firmware and initialize the setting values also, add “FACT_” at the beginning of the filename.
If you want to upgrade the firmware only and leave the setting values as they are, eliminate the “FACT_” from the filename.

Update procedure

1. Turn the power on.

2. Press [MENU] button to display Menu.

3. Select “Features”.

4. Select “Software Upgrade”.

5. Select “Upgrade” to display Upgrade screen.

Firmware Upgrade (Filename example: FACT_TVNB012_00_UF_XX91_AA.ecc)

Upgrade the firmware and initialize the setting values.

The User Upgrade and the Firmware Upgrade (Factory Upgrade) will be done by the same file. If you want to upgrade the firmware and initialize the setting values also, add “FACT_” at the beginning of the filename.

If you want to upgrade the firmware only and leave the setting values as they are, eliminate the “FACT_” from the filename.

Flash Upgrade (Filename example: ALL_TVNB012_00_UF_XX91_AA.ecc)

Upgrade the firmware and initialize the setting values along with the factory default such as White Balance, etc.

Before the upgrade, you will need to make a note of all the factory default so you will be able to set it back on the TV after the initialization.

The Flash Upgrade will be done by it's unique file.

The User Upgrade/Firmware Upgrade (Factory Upgrade) file cannot be used for this upgrade.

Update procedure

1. Turn the power off.

2. Insert the USB storage device to the USB port.

3. Turn the power on.

4. The update will start and the status will appear in the screen.

[If the status screen isn’t displayed, repeat from step 1]

5. When the firmware update is completed, the status will appear in the screen.

Remove the USB storage device from the USB port.

Turn the power off and turn the power on again.

Service mode initial screen with a word “INITIALIZED” will appear in the screen. The color of the word “INITIALIZED” will change from red to green when initialization is completed.

Smps schematic

Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.  If Main Fuse (F601) 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.

HOW TO UPDATE ESS PROGRAM

(1) Rename the file name to download as “LG_(MODEL NAME)_(Vresion).ROM” in upper cases.

ex) XA66 : “LG_XA66_0905180.ROM”

Refer to the Standard for naming of software.

(2) Copy the file to the formatted USB, and burn it.

(3) Move to the USB function, and insert the USB to the set.  The upgrade information will be shown on the screen.

(4) Remove the USB.

(5) Remove and reconnect the power cable when it changes to logo screen from upgrade information.  Then the upgrade process is completed.

HOW TO UPDATE SANYO PROGRAM 

(1) Change the file name to download as “(MODEL NAME)_(Version).HEX”. in upper cases

ex) XA66: XA66_0809262.HEX

(2) Copy the file to the root folder of USB storage.

(3) Put the USB into the set.  Then the upgrade process will be started with the upgrade information.

(4) If the upgrade process is complete, the set will be rebooted with “Complete” message.

HOW TO UPDATE MCS PROGRAM

(1) Change the file name to download as “(MODEL NAME)_(OPTION)_(Version).mcs”. ex) XA66_0000_02.mcs

(2) Copy the file to the root folder of USB storage.

(3) Put the USB into the set. Change set function to USB function.  Then the upgrade process will be started with the upgrade information. FLD display "UPGRADE".

(4) If the upgrade process is complete, the set will be rebooted with “SUCCESS” message, and set auto power off.

(5) Pull out the USB Storage. Press the power key.

Repair notes

1) The pick-up incorporates a strong magnet, and so should never be brought close to magnetic materials.

2) The pick-up should always be handled correctly and carefully, taking care to avoid external pressure and impact. If it is subjected to strong pressure or impact, the result may be an operational malfunction and/or damage to the printed-circuit board.

3) Each and every pick-up is already individually adjusted to a high degree of precision, and for that reason the adjustment point and installation screws should absolutely never be touched.

4) Laser beams may damage the eyes.  Absolutely never permit laser beams to enter the eyes.  Also NEVER switch ON the power to the laser output part (lens, etc.) of the pick-up if it is damaged.

5) Cleaning the lens surface

If there is dust on the lens surface, the dust should be cleaned away by using an air bush (such as used for camera lens). The lens is held by a delicate spring. When cleaning the lens surface, therefore, a cotton swab should be used, taking care not to distort lens.

6) Never attempt to disassemble the pick-up.

Spring has excess pressure. If the lens is extremely dirty, apply isopropyl alcohol to the cotton swab.

(Do not use any other liquid cleaners, because they will damage the lens.) Take care not to use too much of this alcohol on the swab, and do not allow the alcohol to get inside the pick-up.)

Test procedure

General Unit Function (UUT = Unit Under Test)

Switch/Controls:

GAIN control full Counterclockwise (Min)

CROSSOVER (Hz) Full Clockwise (140)

PHASE switch - either position

LFE/LP – LP position

1) From the signal generator, connect one line level (RCA) cable to the Line In jack on the UUT.

2) Turn on generator; adjust to 200mV, 50 Hz.

3) Plug AC power cord in UUT, turn power switch ON.

4) LED should be ON (faceplate). Turn up LEVEL control to full Clockwise (Max).

5) LED should be Green; Bass response should be heard and felt vigorously from woofer and port tube.

6) Turn LEVEL control full Counterclockwise (Min). Turn power switch OFF.

Sweep Function

1) Follow steps 1-5 above, using a sweep generator as a signal source – adjust the generator to 75mV, 50 Hz.

2) Sweep generator from 20Hz to 300Hz. Listen for any rattles, clicks, buzzes or any other noises. 

If any unusual noises are heard, test woofer according to the instructions below.

Driver Function

1) Remove woofer from the enclosure.

2) Check DC resistance of woofer; it should be 5.9 Ω ±10%,

3) Connect a pair of speaker cables to woofer terminals. Cables should be connected to an integrated amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 6.0V.

4) Sweep generator from 20Hz to 1kHz. 

Listen to driver for any rubbing, buzzing, or other unusual noises.

Setting the Initial data

This adjustment is controlled by the CPU (IC8000) through the IIC Bus Data Line in the chassis, and those adjustment data are memorized the memory IC (IC7 00). Therefore, Main board or the memory IC (IC7 00)

is replaced, these data will be disappeared. Readjust should be made. Initial data is provided in the CPU ROM, when the memory IC (IC7 00) is replaced with new one. CPU ROM data is loaded into the memory.

Initial data is provided to operating the monitor basically. For operating the monitor quality performance, further adjustment is required following chassis electrical adjustment.

Receive good quality signal.

2. Enter the Service Mode.

3. Confirm data value to be the same as the Service Adjustment Data Table. If it is different, change to correct data
