Unfortunately, you can't disable the child lock (front panel lock) without a working remote for the TV. If you can find a universal remote that will match the Menu function of the TV, then press menu and find the child lock option. Then press Volume + or Volume - to toggle it to off.
The child lock on a TV can be a
wonderful thing. A parent sometimes cannot be present for the duration of a
kids' show, so the child lock ensures they can't watch programs that are off
limits. The lock can, however, cause unwanted trouble--if it gets accidentally
turned on and you don't know the code, you can find yourself unable to fully enjoy
the full range of available television stations. Follow a few easy steps you'll
be back to watching regular TV in no time.
the manual for your television. Though slightly embarrassing, accidentally
turning on the child lock to a TV is a common problem. The section In the
manual about how to set the child lock feature will also explain how to unlock
a few "universal methods" for unlocking the child lock. Some
televisions have a universal code built in for disabling the child lock --no
matter what your code is. A common code is "0000."
your television for a few minutes. The internal battery of the TV is what helps
remember what your code. If the TV is unplugged for an extended period of time,
it clears the internal memory, which in turn will reset your child lock code.
If your Child Lock has been engaged you can unlock it by pressing and holding the FUNCTION key and pressing the MUTE key on your remote control. The only way to activate and deactivate the lock is with the remote control so ensure that you keep it in a safe place.
If you have lost the manual for your TV you can download a replacement at the following website:
The Child Lock feature prevents unauthorized viewing of the TV. To activate, press and hold the F key, and
then press MUTE. You should see a key symbol appear on the screen. This will lock out all remote functions
(except for Standby). To unlock the TV, press and hold the F key and press MUTE. This will unlock the TV.
Please note that the only way to activate or deactivate the Child Lock feature is via remote control - please
insure that it is stored securely.
i found out on line in the owners manual that if u still have a remote control that came with the tv, u press the tv/av button and enter button at the same time to disable the child lock. New problem: u can't do it with a universal remote, even if its programmed to a magnavox tv. I called the 800 # to buy a remote control and the rep told me that it cost $50, not including the shipping and handling. so my husband put the tv in the car, brought an extension cord and took it to a local tv repairman who was kind enough to use his remote to remove the child lock for us. finally someone who is helpful for free. thanks to all the nice people out there!
Here is the link for the manual;
page 15 towards the bottom - unfortunately you can only remove the child lock with the remote.
If you look on the remote (possibly inside the battery compartment) it should have a model number - sorry i had no luck yet finding it out online - let us know that, and we can try and source a new remote for you.
Try searching for this remote;
DYNATRON MR160 MIRACLE REMOTE CONTROL
It is designed to control all hitachi tvs from 1988, including all the hitachi brand specific functions and seems readily available, no link because you will find lots, maybe somewhere close to you.
Sorry if bad news; hope it helps :)
