Model: KV-32XBR400, KV-36XBR400 No. 507R1
Subject: TV Turns Itself Off. Date: August 8, 2001
Symptom:
(3111) 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.
Solution: 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.
