Hello..I have an old RCA Rca t25001gy television.I've lost the
manual.
Somehow or other I got the "tamper proof" mode locked.. I can't
unlock it...
I've tried unplugging the set for a time, and fresh batteries in the
remote.

Any ideas as to how I can unlock this"Tamper" mode... THe light on the
TV for the mode just blinks..

THanks

Herb
