Child hit something on the remote and now there is a blue screen and it says "no signal"

look first for the source or input button on the remote that changes between the various connections for signal the set has.

Try as you turn set on to instantly press and hold menu.

This usually happens when you are on a source that doesn't have a signal such as a channel with no signal or an AV input that is not connected.

You should look for a button that has TV/VCR or TV/VIDEO on it. I've guessing that you've already tried to change the channel but if not try that.

Last ditch effort in that case may be to unplug the TV for a few secouds. Warning- this may wipe out any settings you have entered such as the channel programming (which channels to skip while surfing) but along with that goes the blue screen.

Was an auxillary input accidently selected? Try selecting inputs to see if this straightens it out. What model set do you have?

I'm afraid you will need the original remote control hand unit folks. Apex TVs use a four digit code to control the v-chip. The override code for many models is 6688. Other sets may not have one, or may have a default code of 1225 instead of an override code.

1. To use the override code:
2. Hit the MENU key to get to the menus.
3. Go down to the SYSTEM menu and hit the right arrow on the remote control.
4. Once in the SYSTEM menu, go to PARENTAL GUIDE. It will ask for your code.
5. Enter the override code listed above. From here, you can turn on and off different rating restrictions, as well as set a new code.

No matter what the V-chip code is set to, the override code will still work. If you have a blank screen with a red key on the bottom left, simply press the (function or F) button and the mute button at the same time. This will unlock the screen and allow you to view the channel as desired

You might want to try the same solution for the V-Chip (this might be the same thing as the child lock, it is worth a try) protection to see if this will help:

Changing V-Chip Settings for MV13L3, TV/VCR Combo 2001.

-Unplug your tv for 1 minute.
-Plug your tv in and turn it on.
-hold the volume down button on the tv at the same time you hold the "0" button down on the remote. This will bring up the "Set V-Chip" blue screen.
-Enter "0000" for the password and hit enter. Enter "0000" to confirm the password and hit enter.
-This will bring up the V-Chip set page. From this page you can: Turn Off the V-Chip, Change the Limits for viewing, etc.
-If you turn off the V-Chip setting, you will not have to deal with this problem again.

If your set has a blue screen with a small red lock on it, yes you are in the child lock mode, if there is no red lock on the blue screen then no you have another problem. The trouble is, if you are in the child lock mode, you cannot get out of it with out the proper remote hand unit. you will need to get an original replacement remote from Here:http://www.remotes.com/remotes/servlet/rs?a=gmi&smodel=GT2015DV&brand_pn=APEX_GT2015DV&mode=large&uid=11834488446870 There is no other way I'm afraid. Good luck

It sounds to me like a child lock function, which is usually what the screen + padlock is on TVs. Usually your original remote would have a button / sequence to unlock the mode. If you still have your original remote, look for a child lock button or refer to your remote manual (and/or TV manual for the child lock feature) to unlock the mode.
