Unlocking child mode lock it is very difficult and nearly impossible without the tv original remote and the secret password word.Tries tv unplug,replug the tv back like about 24 hrs later.That all u could do,some tvs will reset itself and erase the password.
Insignia will tell you that you MUST have original remote to unlock. You press and hold Display button for 5 or 10 seconds. My problem is Best Buy tried to repair mine 3 times and one of those times replaced a board inside and original remote will note work and they will make no attempt to help me figure out what is inside. Mine has been locked for over a year. Locked by accident with universal remove.
1. Locate second power switch on back hidden below curve, left side if facing front of TV. 2. Turn TV on using this power switch while holding in MENU button on right side of TV. 3. This is reset the Lock feature!!
The power button on the TV doesn't work because of the child lock?
I went over the copy of your manual for your TV. It must be the child lock timer problem.
I would try leaving the TV unplugged for 30 mins and see if that reset the TV and releases the lock.
If it doesn't work, the remote needs to be replaced. A universal remotes aren't really universal when you need to use special buttons. The remote made for the TV is the best.
If your TV is the model 47PFL7403D, here's the cheapest place to buy a replacement. http://www.philips.newremotecontrol.com/catalog_item.php?catnum=313922852812
Unfortunately with this model of Insignia you MUST have the remote that comes with that model number in order to unlock it. Other Insignia remotes won't work. So I have ordered another remote from an online company. Hopefully that will work. I'll probably have to call Insignia to have them walk me through it once the remote arrives.
To unlock the Panel Lock,
Parent Lock, or Child Lock, follow these steps:
Turn on your TV.
On the remote, press
the Menu button. The Set-Up
Scroll to the Key
Lock function and set
function to Off.
Press the Exit button to exit.
Note: If you don't have a remote, you may
be able to do the same thing by pressing the Menu button on the front or side
panel of your TV and using the volume or channel up and down buttons on the
TV to scroll to the Key Lock function and set it to Off.
