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.
5. TDA9886 failure: 66% ON, 33% OFF for six times and OFF for a second.
