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 1300µA).
2. Ensure that during normal operation the EHT does not exceed 29 KV ± 1.5 KV (at a beam current of
1300µA). 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.

LED FLASHING CODES
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 offer 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 10).
• Insert a generic led diode between pin 10 and ground (i.e. pin 5) as shows the below picture.
Follow the sequence according to the below information, as a guide to fault finding.
1. Unable to read or write into NVM: 66% ON, 33% OFF twice and OFF for a second.
2. MSP 3410 failure: 66% ON, 33% OFF for three times and OFF for a second.
3. SDA 9380 failure: 66% ON, 33% OFF for four times and OFF for a second.
4. VSP 9402 failure: 66% ON, 33% OFF for five times and OFF for a second.
