Subject: TV Turns Itself Off. Symptom: (3111)
Date: August 8, 2001
The TV turns itself off after the customer has been watching it for a while. It may turn off within minutes of turning it on, or it may take an hour or more before it turns itself off. The set can usually be turned back on again by cycling the TV's front panel power switch. This symptom may be caused by a drift of the hold-down adjustment that was set at the factory. As this adjustment in the field requires the replacement of 3 potentiometers on the D-board and the availability of a precision high-voltage meter (0.2 Kv resolution), the recommended solution is to replace the D-board.
