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 30KV, (at a instantaneous beam current of 300µA). 2. Ensure that during normal operation the EHT does not exceed 27.5KV (at a beam current of 800µA). 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.

HOTEL 1 HOTEL 2 HOTEL 3
Blockade of tuning functions Blockade of tuning functions Blockade of tuning functions
Restriction of sound Start on SCART mode + SW when SCART IS ACTIVE (Front Panel inactive) VCR constant changed
Hotel 1 Mode: blockade of the TUNING function by modifying the value in 0A address of the NVM. -This change besides blocking the tuning function, makes the TV always starts to operate in program 1. Procedure: A) Press the volume up or volume down buttons (RC) as far as the NVM address (green colour) displays "0A" location. Check the NVM value (red colour) displays the NORMAL VALUE . B) Pay Attention: Press the button 2 (RC) only once. The NORMAL VALUE has been changed to the HOTEL 1 MODE VALUE now. If the button 2 (RC) is pressed again the NORMAL VALUE is recovered. For the same reason, if a wrong button has been pressed, NORMAL VALUE can be recovered by pressing the same button again. See NVM table on page 6. Restriction of Sound Volume: by modifying the R314 value. Change R314 value from 1K (VRS-TVIJD102J part code) to 39K (VRS-TV1JD393J part code), so the maximum level of sound can be limited from 100% to 50%.

Hotel 2 Mode: by modifying the value in 57 address of the NVM . -When the TV set is switched on by main it starts working in SCART mode. -When the TV is in STAND-BY mode and it is connected to a VCR through a 21 pins wire, it may be switched on simply by SLOW SWITCH (VCR in PLAY mode). -In these circumstances the Front Panel Control Keys does not work. Procedure: A) Press the volume up or volume down buttons (RC) as far as the NVM address (green Colour) displays "57" location. Check the NVM value (red colour) displays the NORMAL VALUE . See NVM Table on page 8. B) Pay Attention: Press the button 0 (RC) only once. The NORMAL VALUE has been changed to the HOTEL 2 MODE VALUE now. If the button 0 (RC) is pressed again the NORMAL VALUE is recovered. For the same reason, if a wrong button has been pressed, NORMAL VALUE can be recovered by pressing the same button again. Hotel 3 Mode: by modifying the value 57 address of the NVM. -When this it is activated VCR mode is set in all programs. Procedure: A) Press the volume up or volume down buttons (RC) as far as the NVM address (green colour) displays "57" location. Check the NVM value (red colour) displays the NORMAL VALUE. B) Pay Attention: Press the button 1 (RC) only once. The NORMAL VALUE has been changed to the HOTEL 3 MODE VALUE now. If the button 1 (RC) is pressed again the NORMAL VALUE is recovered. For the same reason, if a wrong button has been pressed, NORMAL VALUE can be recovered by pressing the same button again. See NVM Table on page 8. Finally press the Mains Power Button to switch OFF the TV SET . The changes made are stored automatically when the TV SET is switched OFF. Check the Hotel Functions work OK.
