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.

Follow the sequence according to the information below, as a guide to fault finding.
1. Unable to read or write into NVM: 66% ON, 33% OFF twice and OFF for a second.
On
2. MSP failure: 66% ON, 33% OFF for three times and OFF for a second.
On
3. VPC failure: 66% ON, 33% OFF for four times and OFF for a second.
On
4. SDA failure: 66% ON, 33% OFF for five times and OFF for a second.
5. DDP failure: 66% ON, 33% OFF for six times and OFF for a second.
NOTE:
If you want to check that the system is working, open resistor R307 to avoid I
flash three times and OFF for a second, showing MSP failure.
Then the system is working properly.
