For safety, this LCD color television has a function to turn OFF the power automatically when an abnormal
condition occurs in the lamp or lamp circuit (lamp error detection).  If an abnormal condition should occur in the
lamp or lamp circuit, D3600-03 and Q3600-02 will operate to send a lamp error signal to IC2001 (pin (42)),
resulting in the following:

1

 About 5 seconds after the power of the television main body is turned ON, the power is turned OFF.  (The
power LED located on the front of the television changes from green to red.)

2

If 

1

 is repeated five times successively, it becomes impossible to turn ON the power. (The power LED

remains red.)

~

 For measures to be taken, refer to the service manual.
