                                        SIX BLINKS OF STANDBY LED
There are three possibilities for this fault:

1. Short audio amplifier outputs.
2. Lose of 15V supply line.
3. Lose of 9V supply.

The key to determine what to check first is if audio is heard before the TV shut off.  

• If audio is heard before shut off, check the 15V power supply at CN7503/pin-1.  If this voltage is missing replace the G1/G2 board.  If this voltage is present, check fuse PS7001 for a possible easy fix.  If the fuse is found OK, replace the 'AU' board.
• If no audio is heard before TV shut off, check for 9V at CN9502/pin-1.
• If the 9V is missing replace BU board.  If 9V is present check and confirm that the protection circuit output voltage is making it to the Main Microprocessor IC1001/pin-26.  If 2.8V is present here, then the Main Microprocessor is defective.  Replace BU board.  If voltage at IC1001/pin-26 is (0V) the audio output circuit has actually failed.  Replace AU board.  a shorted audio output or a DC voltage level measure across the audio output will cause a 6 blinks of LED [protection mode].  In either case the problem will exist in the audio circuitry on the AU board.
