Safety Instructions - Resolder Notice

Safety regulations require that during a repair:

• the set should be connected to the mains via an isolating transformer

• safety components, indicated by the symbol:

should be replaced by components identical to the original ones

• when replacing the CRT, safety goggles must be worn

Safety regulations require that after a repair the set must be returned in its original condition. In particular, attention should be paid to the following points:

Note:

This resoldering is advised to prevent bad connections due to metal fatigue in solder joints, and is therefore only necessary for television sets older than 2 years.

• As a strict precaution, we advise you to resolder the solder joints through which the horizontal deflection current is flowing, in particular:

- All pins of the line output transformer (LOT)

- flyback capacitor(s)

- S-correction capacitor(s)

- line output transistor

- pins of the connector with wires to the deflection coil

- other components through which the deflection current flows

• Resolder points are marked by a white circle on the bottom of the CBA.

• The wire trees and EHT cable should be routed correctly and fixed with the mounted cable

clamps.

• The insulation of the mains lead should be checked for external damage.

• The mains lead strain relief should be checked for its function in order to avoid touching the

CRT, hot components or heat sinks.

• The electrical DC resistance between the mains plug and the secondary side should be checked (only for sets which have a mains isolated power supply). This check can be done as follows:

- unplug the mains cord and connect a wire between the two pins of the mains plug

- set the mains switch to the on position (keep the mains cord unplugged!)

- measure the resistance value between the pins of the mains plug and the metal shielding of

the tuner or the aerial connection on the set. The reading should be between 4.5 Megohm and 12 Megohm.

- switch off the TV and remove the wire between the two pins of the mains plug

• The cabinet should be checked for defects to avoid touching of any inner parts by the customer.

CAUTION: USE A SEPARATE ISOLATION TRANSFORMER FOR THIS UNIT WHEN SERVICING

Page 29

J8 CHASSIS SERVICE ADJUSTMENTS Service Adjustment Notes:

REQUIRED TOOLS FOR SERVICING

Isolation Transformer Multimeter Oscilloscope High Voltage (100:1) Oscilloscope Probe Sencore VG91 Universal Video Generator

Caution: The J8 chassis incorporates a "hot" ground system. Always use a separate isolation

transformer when applying power to the exposed chassis.

Unless Otherwise Specified:

1. All service adjustments are "hot" voltagewise. For maximum safety, ensure the use of properly insulated tools.

2. Refer to the J8 Main Chassis Printed Circuit Board for location of test points and adjustable components.

3. Grid Locations (Ex.: D-3) next to the reference numbers for components refer to the Main Chassis Printed Circuit Board.

Focus Adjustment

1. Tune the set to a local or cable station.

2. Adjust the Focus Control (located on the upper part of the flyback transformer) for best picture details at high light conditions.

Degaussing the Television

1. Position the television so that the screen faces the direction it will be facing when in use.

2. Ensure the set is turned off.

3. Move a degaussing coil in a circular motion slowly around the sides and front of the set.

4. Continue this motion while withdrawing the degaussing coil at least six feet from the television, and then disconnect the degaussing coil from its power source.

Service mode

Introduction

The service mode is a combined Service Default Mode (SDM) and Service Alignment Mode (SAM). This service mode is Called SDAM. When the television is in SDAM, all normal features (such as volume control and direct channel access) are available. In service mode there will be an "S" displayed (in green) at the top right of the screen. All other Service OSD’s will also be in green.

Error buffer

Error codes will indicate failures in the television. A unique error code is available for:

• activated protection

• failing I2C device

• general I2C error

• RAM failure (e.g. internal RAM of microprocessor)

Page 30

Other error codes are:

• Video Chip start-up failure

The last five errors, stored in the NVM, are shown in the service menu. This is called the error buffer. An error code will be added to the buffer if it differs from the last error detected. If errors occur simultaneously, and the codes for these errors differ from the errors currently on screen,

the display will be updated to reflect this change. The error that is found last is displayed on the left. The error code to the right should be used to solve a

multiple error fault. If an intermittent fault occurs refer to the stored error code.

Example:

Suppose the display shows: 7 5 2 0 0

In this case, the last error detected was a Stereo I2C error. A seven (7) appears at the 1st position (on the left), and pushes the previous error(s) detected one space

to the right. The following error codes have been defined:

0 = No error 1 = Master Protect (Master Protect, Monitors Beam Current/Xray(6732), 8v LOT(6730), 25v

LOT(6731), vertical(6755), tuner 5v (6733), these diodes will pull pin 26 of micro 7600 low and shut off TV.

A one (1) will be stored after the fault is cleared.) 2 = I2C error while communicating with a processor 3 = General I2C error (*)

4 = Internal RAM error micro controller 5 = I2C error EEPROM error 6 = I2C error PLL tuner 7 = Stereo I2C error

Note: I2C =(SCL/SDA) (*) General I2C error means: no I2C device is responding to the particular I2C bus.

Possible causes: SCL Short circuit to GND, SDA Short Circuit to GND, SCL Short Circuit to SDA, SDA Open Circuit (at uP pin), SCL Open Circuit (at uP pin)

Cause and Effect

In case a failure identified by an error code automatically results in other error codes (cause and effect), only the error code of the MAIN failure will be displayed. Example: In case of a failure of the I2C bus (CAUSE), the error code for a „general I2C failure“ will be displayed. The error codes for the single

devices (EFFECT) won’t be displayed.

NVM replacement or Defective NVM

After replacing a NVM (or with a defective/no NVM) default settings will be used that enable the set to start up and that allow access to the Service „SDAM“ Mode.

Service unfriendly modes

In the service modes, a number of modes/features are ignored since they interfere with diagnosing or repairing a set. These are „service unfriendly modes.“

Page 31

„Ignoring“ means that the event that is triggered is not executed, the setting remains unchanged.

ways:

(Example: Timer OFF: 8:00 PM; the set will not switch OFF in service mode at 8.00PM, but the setting will remain). These modes are:

• Blue mute.

• Auto switch off (when there is no ident signal).

• Automatic user menu time-out (menu switches back/OFF automatically) except for Surf menu.

Convergence and Purity Adjustments

Notes:

1. The following adjustments were performed with a Sencore VG91 Universal Video Generator.

2. Set the VG91 Generator as follows: STD TV Ch. 3, RF-IF Range set to HI, RF-IF Level set to NORMAL

(1), Video Pattern = Raster, R-G-B raster controls OFF, Mode Switch set to L+R, Audio Frequency set to 300Hz, and 0 Pilot (max. CCW).

3. Connect the RF output of the generator to the Television Antenna Input, and adjust the VG91 level to

remove any snow from the raster.

Pre-Convergence Procedure

Note: The degaussing procedure should be performed prior to this adjustment.

1. Place the multi-pole Purity and Convergence Assembly with the 2-Y pole purity rings directly in the gap between the G2 and G3 (focus) grids as

2. Enter the Service Default Alignment Mode (SDAM) in either of the following two ways: a. Press the following key sequence on the remote control transmitter while the set is in Standby

mode: 0-6-2-5-9-6-Status (Do not let the sequence time-out between entries)

b. Short service pin 0239 (on the CBA) to ground and switch power-on.

3. Apply a center cross or crosshatch pattern to the antenna/cable input terminal.

4. From the SDAM menu, use the Menu Up/Down buttons to highlight CO (Color Cut-off).

5. Use the Menu Right button to enter the CO sub menu.

6. Using the Menu Up/Down buttons select G (green).

7. Using the Menu Left button set green to minimum.

8. Loosen the yoke clamp screw, pull the yoke back, and remove the three yoke wedges.

9. Slide the yoke all the way forward so that it rests against the bell of the CRT.

10. Tighten the yoke clamp screw so that the yoke does not drop away from the bell of the CRT.

11. Slowly spread, and if necessary, rotate the 2-Y pole purity rings so that the red and blue lines are at least parallel and preferably coincide at the 6:00 and 12:00 positions

12. Proceed to the Color Purity Adjustment.
