For starters:
With all secured and everything connected ... While LED is blinking, press the remote's Vol up once and record number of blinks ___. While LED is blinking, press the remote's Vol down once and record number of blinks ___. This can help in determining if the symptom shown by the TV when it first failed (Most likely during operation), has changed to another blinking code when checked by the service technician.
LIST OF BOARDS POSSIBLY CAUSING THE FAILURE
MOST COMMON | 2ND | OCCASIONALLY | RARELY
SS | Panel | A | C2
Note: When connector SC20/A20 is disconnected on the 2011 models, the TV shuts down with 8 blinks. When this is done on the 2009 and 2010 models, the TV shuts down with 6 blinks.
8 Blinks SOS: Pin 10 of the Application Specific IC – ASIC (IC5000) monitors the status of the SS board. During normal operation, a low from the SS board (SS33) is output to pin 10 of IC5000 from connector A3. If an abnormality is detected on the energy recovery circuit, pin 10 of IC5000 goes high. This change of input, causes the voltage output a pin 12 to change. This change of voltage is provided to the Peaks-Lda3 IC (IC8000). As a result, the unit shuts down and the power LED blinks 8 times.
8 Blinks condition is also caused when the connections between the panel’s flex-cables and the sustain board are broken or the connector are not properly seated.
