Re: APEX 19 inch Color TV
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.
• If your TV asks for a 4-digit code or password please enter 3308 or 6688 to unlock the screen or reset any preset rating levels.
• If you have a GT2011J or GT2011S Television, hold the (Display) button for 10 seconds, it will unlock the screen. If password or code is requested, try 3308 or 6688.

Sounds like a power supply problem on your TV. First rule with electronics... if you don't know much about them, don't open them. Second rule, use the process of elimination, starting with the least evasive action possible. In your case, rather than opening up the TV, you would have been better off to try a replacement cable first, then work your way up the repair chain from there. As it is, being a 19 TV and a Coby brand which is essentially a throw away when it goes bad, you're probably going to have to replace it. But check with a local authorized repair shop before doing anything drastic. And then remember to let the Pros take care of internal electronic issues. Even if it's under warranty, the manufacturer may not honor it because you opened the TV yourself. Most warranties specify that doing so invalidates the warranty. Sorry for the bad news. Hope it answers your question.
Hi there, Sounds like someone activated the lock (either V-chip or Parental Locking) on your TV. The only way around this is to find out who did, and get the code. If you provide a model name and number, I can see if there's a workaround.
Your laptop will have a VGA output or possibly a S-video out. For the
VGA you'll need a standard VGA cable. Plug the cable in to your laptop
and the PC input of your TV. If your TV does not have PC input it may
have a DVI input. IF it does you can use a VGA/DVI adapter to plug it
in. If it doesn't have a DVI input you can use the S-Video output on
your laptop with a standard S-video cable. After the connection to your
TV is made you will have to toggle alternate display by pressing and
holding your [Fn] key and pressing F4, or F5, or another F# key. It's
the one that looks like a TV screen. Press once to turn on output,
press again to turn off your laptop screen, press again to go back to
laptop screen only
If the TV does not get a screen by the time desktop appears, open your graphic controls (usually on bottom right of menu bar) and select external monitor, then set parameters (size, PAL/NTSC, etc)
If this utility is not available there, look for a color-coded FN key, and a correlative same color icon on F keys (F1-F12) that resembles a monitor (rectangle),. Press both of these simultaneously, which brings up monitor option there.
