Solution: Ensure the firmware of the TV is up to date (these models had an update for poor start up with 1 blink shut down) If the firmware is up to date, Check the error code carefully as described in the service manual for the meaning of the blink codes. To confirm the error count you can check the last 5 error counts by going into the service mode. Go to service mode > access SERVICE TOOL and examine what the entries for PTCT (protection counter) say. 01 error logged would mean 1 blink = inverter problems (thus check its 24v supply and drive signals (from DG pcb , DG26 INV ON will be 3V). Replace LCD panel if supplies and drive is OK Confidential Page 1 318531838567584BR REV1
