Self-diagnostic function

The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER LED will automatically begin to flash. The number of times the LED flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER LED flash indicators is listed in the instruction manual for the user’s knowledge and reference. If an error symptom cannot be reproduced, the Remote Commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
Diagnostic Test Indicators
When an error occurs, the STANDBY/TIMER LED will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the LED will identify the first of the problem areas.
Results for all of the following diagnostic items are displayed on screen. If the screen displays a “0”, no error has occurred.

If a +B overcurrent is detected, stoppage of the vertical deflection is detected simultaneously.  The symptom that is diagnosed first by the microcontroller is displayed on the screen.

If standby/stereo LED flashs 8 times, unplug the unit and wait for 10 seconds before performing the adjustment.

Display of Standby/Timer LED Flash Count

Release of TIMER STAND BY indicator blinking
The TIMER/STANDBY indicator blinking display is released by turning OFF the power switch on the TV main unit or removing the plug from the power.

Self-Diagnosis Screen Displays

In cases of malfunctions where it is not possible to determine the symptom such as when the power goes off occasionally or when the screen disappears occasionally, there is a screen display on whether the malfunction occurred or not in the past (and whether the detection circuit operated or not) in order to allow confirmation.

Screen Display Method
Quickly press the remote command button in the following order from the standby state

Self-Diagnosis Screen Display
The results display is not automatically cleared. In case of repairs and after repairs, check the self-diagnosis screen and be sure to return the results display to “ 0 ”.
If the results display is not returned to “ 0 ” it will not be possible to judge a new malfunction after completing repairs.

Method of Ending Self Diagnosis Screen
When ending the self-diagnosis screen completely, turn the power switch OFF on the remote commander or the main unit.

Self-Diagnosis Function Operation
+B overcurrent (OCP)
Occurs when excessive current flows through R6812. The increase in voltage across Q6803 causes it to turn on which sends a high signal to the micro.
+B overvoltage (OVP)
IC6801 detects +B OVP condition and turns on Q6802. This sends a high signal to the micro and also shuts down the AC relay.
V-STOP
Occurs when an absence of the vertical deflection pulse is detected by pin 56 of IC0401 (MA Board). Power supply will shut down when waveform interval exceeds 2 seconds.
White Balance Failure
If the RGB levels* do not balance within 2 seconds after the power is turned on, this error will be detected by IC0401. TV will stay on, but there will be no picture.
*(Refers to the RGB levels of the AKB detection Ref pulse that detects 1K).
Low B OCP/OVP
Occurs when set 5V is out.
Horizontal Deflection Stopped
Occurs when either:
1) a +B overcurrent is detected (Q6803), or
2) IC0401 (MA Board) is damaged.

Screen voltage adjustment (g2) (coarse adjustment)

1. Receive the Monoscope signal.
2. Set BRIGHTNESS to 50% and PICTURE to minimum.

Screen (g2) adjustment (fine adjustment)

If the jig described below is available, it is recommended that the G2 Fine Mode Adjustment be performed to set the screen controls to their optimal condition. If desired, you can build the jig illustrated below,
using 3-watt resistors. Please note that if the proper voltage is not obtained with the listed resistor’s values, then increase or decrease one of the values in the resistor network to obtain the correct voltage.
1. Select VIDEO-1 mode no signal applied (the screen must be black).
2. Connect the G2 JIG.

Please do not attempt to disassemble this device, if you don’t have needed tools and sufficient experience. This is not an easily repairable device for a customer. Contact the service centre for Panasonic to get it repaired. No user repairable parts inside.

How to Replace the Lithium Battery

The lithium battery is a critical component.

(Type No.: ML-614S/DN Manufactured by Energy Company, Panasonic Corporation)
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in equipment designed specifically for its use.
Replacement batteries must be of the same type and manufacture.
They must be fitted in the same manner and location as the original battery, with the correct polarity contacts observed.
Do not attempt to re-charge the old battery or re-use it for any other purpose.
It should be disposed of in waste products destined for burial rather than incineration.

1. Remove the Monitor P.C.B.
2. Unsolder the Lithium Battery "ML-614S/DN" and then replace the new one.

How to Define the Model Suffix (NTSC or PAL model)

There are eight kinds of SDR-H100/H101, regardless of the colours.
 a) SDR-H100P
 b) SDR-H100PC
 c) SDR-H100EB/EC/EF/EG/EP, SDR-H101EB
 d) SDR-H100EE
 e) SDR-H100GT
 f ) SDR-H101GA/GN
 g) SDR-H101GK
 h) SDR-H101PR/PU/GC
What is the difference is that the "INITIAL SETTINGS" data which is stored in Flash ROM mounted on Main P.C.B.

To define the model suffix to be serviced, refer to the nameplate which is putted on the bottom side of the Unit

After replacing the MAIN P.C.B., be sure to achieve adjustment.

Stereo mode: 80 W + 80 W (4Ω at 1kHz)

 The pick-up incorporates a strong magnet, and so should never be brought close to magnetic materials.
 ✓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.
 ✓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.
 ✓Laser beams may damage the eyes. 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.

✓ NEVER look directly at the laser beam, and don’t allow contact with fingers or other exposed skin.

 ✓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.

seconds for execution.

NOTE: After "reset", turn the unit off and on again.

Firmware Update

This procedure should only be performed when the equipment is abnormal in its operation, or when there is an official communiqué to carry out such a procedure.  Do not upgrade if the equipment is working properly.  Carefully read the entire procedure and perform the task as described below.  If in doubt, always seek the help of H-Buster technical support.

Firmware (software update)

Initial Procedures.

Needed tools:

- An empty and formatted pen drive (FAT32) - minimum 512MB;

- Remote control of equipment;

- Latest version downloaded from the services website.

To obtain the latest version, log on to the H-Buster service website and download as the LCD panel model (if present). If you have any questions, contact technical support.

How to identify the Panel Type

Service Mode Menu

Rear side of LCD Panel

Identification of the LCD panel by the label attached to the reverse (inner part)

Copying the firmware to USB Memory Key

The file that is on the services site is "zipped (compressed)." To unzip it, it is necessary to have a decompress program installed on your computer (eg Winzip, WinRAR, etc.) Save to the desktop and unzip it to the PC. If the decompress or program creates open the folder and copy to the pen-drive the file that is inside the folder (NOT COPY TO ALL PASTE).

The name of the file to be copied to the pen drive SHOULD NOT BE CHANGED, CASE CONTRARY TV WILL NOT RECOGNIZE THE FILE

Updating the firmware

Follow the procedures below carefully:

1) With the TV working, connect the pen drive with the recorded program to the USB port;

2) Press the MENU button on the remote control and go to the CHANNEL option with the navigation keys and press OK;

3) In the CHANNEL menu, scroll to the next page where "Update Software" will appear and press OK;

4) The confirmation question will appear on the screen, confirm and press OK;
