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.
