IMPORTANT SERVICING NOTES Only qualified service personnel are allowed to carry out maintenance and repair of this receiver.
SERVICING OF HIGH VOLTAGE SYSTEM AND CRT It is important that the static charge is removed from the high voltage system when carrying out work on the receiver. This can be achieved by connecting a 10K resistor (with a suitably insulated lead) from the CRT cavity connector to the CRT ground tag. This must be carried out with the AC supply disconnected from the receiver. Note the following: • The CRT in this receiver employs Integral Implosion Protection. • If the CRT has to be changed it MUST be replaced with the correct type for continued safe working • DO NOT lift the CRT by its neck. • When handing the CRT, ensure that shatterproof goggles are worn. • Ensure that the CRT is discharge before handling.
X-RAY This receiver is designed to keep any x-ray emission to an absolute minimum. Some fault conditions and servicing procedures may produce potentially hazardous x-ray radiation levels. This is a problem when in close proximity to the receiver for long periods of time. To reduce any risks associated with this, please observe the following precautions: 1. When undertaking any servicing on this chassis, DO NOT increase the EHT to more than 32 KV, (at a instantaneous beam current of 1500µΑ). 2. Ensure that during normal operation the EHT does not exceed 30KV±1.5KV (at a beam current of 1300µΑ). This level has been preset in the factory. Always check that this level has not been exceeded after carrying out any repair on the receiver.. 3. DO NOT replace the CRT with any other type than that specified in the parts listing as this may cause excessive x-ray radiation.
BEFORE RETURNING THE RECEIVER TO THE CUSTOMER In addition to the above checks, the following should also be carried out before returning the receiver to the customer. 1. Inspect all the leads to ensure that they are dressed correctly and that they are not obstructed or pinched by any other parts. 2. Ensure that all protective devices are in good condition. These will include nonmetallic control knobs, insulating fish papers, cabinets backs, compartment covers or shields, mechanical insulators, etc.

ADJUSTMENT PROCEDURES All adjustments to this chassis, except for focus, are carried out in the service mode.
• SERVICE MODE
The service mode is provided to enable the engineer to correctly set up the receiver to the CRT fitted in the set. Note that these adjustments may vary from one receiver to another. To enter the service mode, carry out the following procedure. 1. Connect a test pattern to the antenna terminal. 2. Tune the receiver to this signal. 3. Turn the receiver off using the mains switch. 4. Press volume down and channel up buttons on the front of the receiver at the same time. 5. Keeping these buttons pressed, turn the mains on. 6. When the set starts up it will be in service mode. 7. Release the two buttons.

• Use the channel up and down buttons to move between the options. • Use the volume control buttons to change the data. • To store the data, use the stand-by button on the remote control. • To exit the service mode, turn the receiver off using the mains switch. When the service mode is entered the following On Screen Display appears -SERVICE SOFTWARE AND HEXADECIMAL COUNTER DISPLAY: SW ON XXXX SW OFF XXXX HOURS ON XXXX The figures displayed in the XXXX locations are hexadecimal representations of the number of times that particular function has been executed. For example if the hexadecimal number displayed after SW ON was 0E4A, this would correspond to the receiver being turned on 3658 times. Adjustment menu: The following adjustments can be carried out in the service mode. • Horizontal Shift • East West Width • Pin Phase • Pin Amp • Corner Amplitude • Corner Symmetry • Vertical Linearity • Vertical Angle • Vertical Bow • Vertical Amplitude • S Correction • Vertical Shift • Red Gain • Green Gain • Blue Gain

28HW-53E G2, Cut Off and Gain Adjustments (alternative method). In the event off a Colorimeter not being available, please follow the following procedures to obtain correct G2 and Grey scale settings. 1. Tune the set to the output of a RF signal generator (cross hatch pattern). 2. In the user menu, set the picture levels to the FACTORY settings. 3. In the user menu, set the tint control to its central position. 4. Enter the service mode. 5. Set the ABL levels in the NVM by adjusting positions 60, 61, 62, 63, 64 and 65 on page 00 to read 80. Store each location by pressing the stand-by button on the remote control. 6. Adjust the G2 and grey scale as below. When adjusting the grey scale the following boxes will appear on the screen. (RED) (GAIN) (CUT OFF)
** e.g. 70
(GREEN)
(BLUE)
** **
** **
i. Using cross hatch pattern set the G2 so that the display in the Red cut off box reads between 60 and 80 as above. NB. When adjusting the grey scale, the figures displayed in the boxes are an indication of the CRT’s performance only. The data to be adjusted is contained in the box at the bottom right corner of the picture. ii. Select a grey scale signal, then set the Red Cut-off level to 32 and the Red-Gain to 50. iii.Leave the Red Cut-off and Gain as above and adjust Green and Blue Cut-off and Gain to achieve correct grey scale tracking. As with all grey scale adjustments it will be necessary to readjust the settings to achieve good tracking. Changing NVM Data To change the data contained within the Non Volatile Memory, it is necessary to first select the page the data is stored in, then the position and finally to change the data itself. The procedure below outlines this process. 1. While on ALTER NVM PAGE, use the volume up/down buttons to change this data (data is shown in hexadecimal format). 2. Press the channel up button and ALTER NVM POSITION appears, use the volume up/down buttons to change this data (data is shown in hexadecimal format). 3. Press the channel up button and ALTER NVM VALUE appears, use the volume up/down buttons to change this data (data is shown in hexadecimal format). 4. Once this data has been set, press the standby button to store. 5. If another NVM value has to be changed, use the channel down button to select the page or position and repeat as necessary. Note: DO NOT change any NVM data, unless you have been advised to do so by a Sharp representative. If data is incorrectly changed, serious damage may occur to the receiver.
Contrast Adjustments Three types of contrast levels can be varied as listed below: • TELETEXT MIX MODE CONTRAST • TELETEXT CONTRAST • OSD CONTRAST Use the volume up/down buttons to adjust to a suitable level, then press the standby button to store.

28HW-53E DVCO Adjustment (PAL)
LED FLASHING CODES
Carry out the DVCO Adjustment (PAL) as shown below: 1. Receive a Phillips pattern signal. 2. While in the DVCO ADJUSTMENT (PAL) menu, press the standby button. 3. The adjustment will be carried out automatically and stored.
This model is not provided with stereo led, so to let “flashing codes” for IC failures detection when the TV set does not work, we have answered with the next solution: • The detection of failure will be made with an external LED. • The output of the flashing code will be via AV1 (pin 12). • Insert a generic led diode between pin 12 and ground (i.e. pin 5, 13 or 21) as shows the below picture.
DVCO Adjustment (NTSC) No adjustment required. 20
Auto Installation On/Off
21
To return the receiver to the original Auto Installation mode, using the volume up or down button, set the Auto Installation On/Off to On. This setting is automatically stored and when the receiver is turned on the next time it will start up in Auto Installation mode.
