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.
