Powers on for just 5 seconds then off

The instructions on letting the Hipi remote to seach for the code that came with my remote are not correct. I used the instructions from HOWTO.COM and printed below. There are two changes from the printed instructions. The first is to push the <TV> button after the <Code Search> button. The second is that the <Enter> button saved the code not the <MUTE> button.

Instructions
1
Turn on the Vizio TV.
2
Aim the Jumbo Universal Remote at the Vizio TV and hold down the "Code Search" button on the remove for roughly 3 to 5 seconds. The LED lights on the Jumbo Universal Remote will come on.
3
Press the "TV" button at the top of the Jumbo Universal Remote.
4
Start pressing the "ON/OFF" button repeatedly until the Vizio TV turns off. (This took only a few tries for my Vizio TV)
5
Press "Enter" on the remote immediately after the Vizio TV turns off to save the code.
6
Test the Jumbo Universal Remote by trying to control the Vizio TV with the remote. If the control doesn't work with the remote, repeat the entire process.

If you have a DIRECTV white remote, press "menu" then "settings," "setup," "remote", and follow the on-screen instructions.
If using a gray or black remote,

Make sure your TV is turned on.

Slide the mode switch at top of remote to "TV".

Press and hold the MUTE button. This is located above the number 1 button.

While still holding down MUTE, press and hold the SELECT button until green light at the top of the remote flashes twice.

Then enter 9911, the green light on remote should flash twice.

Point remote at TV and press CHANNEL UP button. Tap the CHANNEL UP button repeatedly until the TV powers off.

When the TV powers off, press and release the SELECT button.

You might just want to try to force it to shut down by holding the sleep wake button on the top of the iPod for about 5 seconds. After it powers down, wait about 5 seconds, then hit the power button on top for about 1 second to turn it back on. After it powers up all the way you should be able to unlock your iPod.
Hope that helps!

Here's how to scan for TV codes on your DIRECTV remote

1.Make sure your TV is turned on.

2.Slide the mode switch at top of remote to "TV".

3.Press and hold the MUTE button. This is located above the number 1 button.

4.While still holding down MUTE, press and hold the SELECT button until green light at the top of the remote flashes twice.

5.Then enter 991, the green light on remote should flash twice.

5b. Press 1 again (it will flash twice again), then you press the power on button at the very top right.

6.Point remote at TV and press CHANNEL UP button. Tap the CHANNEL UP button repeatedly until the TV powers off.

*If you hit channel up very fast, you risk going past the code. Pressing channel down will back it up. I alway hit channel up very fast till the tv turns off, then back it up slowly till it comes back on.

7.When the TV powers off, press and release the SELECT button.

*Note: If the green light flashes three times before TV responds, then all codes have been cycled through. Our remote controls are guaranteed to program to your DIRECTV receiver, however your TV may not be compatible with our remote control.

I need sreen for LG 4LC7D-UB because the screen is damaged

You can only remove the "lock" function by using a DELL remote control (must be a Dell remote) and go to menu and follow instructions.

Good luck

I had the same problem happen this afternoon, so I took it apart, and the source of the problem is the key controller panel (behind the buttons). It's held in place by 2 screws, if you take the case apart, which is literally only 15 or 20 screws, and then loosen the 2 screws holding the key controller panel on, and then use a small screwdriver to space it out from the button caps. Tighten the screws, and put it back together. Just be careful not to let it go too far to the other side, or you'll have a problem with the menu going on and off at random, which is just as annoying.
