Hello, There is not a Timer circuit in the receiver. Offhand these symptoms would indicate that the processor on the Mainboard of the receiver is acting faulty- since this provides the turn on command to the unit. As an attempt at a reset, disconnect the receiver from power for a full 30 minutes, then plug it back in. If this is a simple reset issue then this will cure the issue. However if it does not, then it does indicate a faulty processor in the Mainboard of the receiver, which would require repairs. To fix this would require at least heating up the processor chip to re-flow the solder joints, and in the worst case- replacing the processor chip. The average cost for this type of repair is in the $150 range and may not be cost effective on a unit of this vintage.

You're welcome. In the worst case, if the reset does not fix it, you could always put the receiver on a switched power strip that you simply turn off when the unit is not in use to prevent it from turning on, on it's own.
