This is not a sensor problem. The problem is inside the main system control circuit section. Some voltage loss may cause this type of problem. Contact any experienced service technician. The fault location is a skilled work, and not an easy one for a user.

SOURCE: LG 42LC7D TV does not want to chg channels after 5 min of use

There are some inductors that are out of spec. LG's original SB said to replace some of these with a jumper, but it only lasted a couple months.

You need to have the Total Main Assy replaced.

SOURCE: TV freezes when switching to a digital channel

The problem your describing can be contributed to your cable box. Depending on your cable company there are times when the box has trouble translating the signal to the tv. You tv is operating normally. Suggest to the cable company to switch your box.

When I put the batteries in the remote it would turn the tv on,I followed the directions for putting the code in and after doing that it won't even turn the tv on.


I've not had much luck with "provided" codes, probably because there are just so doggoned many TV models out there. Most remotes have instructions on how to let the remote itself find the code. I found the manual online
(http://tv.manualsonline.com/manuals/mfg/ge_appliances/24991.html). Adapted from the manual:
1. Make sure you have batteries correctly inserted in the remote.
2. Turn ON the TV manually.
3. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
4. Press and quickly release the desired mode button [TV, in this case]. The red indicator blinks off once.
5. Press the CHANNEL UP button repeatedly (up to 300 times) until the device to be controlled changes channel. The red indicator blinks off with each button press.

Code Search starts from the currently stored three digit
number under that mode. Sometimes the first code that "works" with your device may only allow limited functionality (e.g. the MENU button might not work).
There may be a code that performs more functions.
Continue the code search process until the best code is
found.
Press the DOWN button to backtrack through the library
until the device changes channel. Pressing
CHANNEL UP changes direction to forward
again.
6. Press and release ENTER to install the code.

Change the batteries in your remote, this is a common issue with batteries that are low on charge.
Also if you find that your TV intermitently changes channels and no one is even touching the remotethis is the same problem.

My TV changes channels or source by itself. I


This may or may not be your solution.

The tact switches (push buttons) mounted on the circuit board may need to be replaced (old, worn, sticking). These are the buttons that are pressed in when you use the controls on the television set (volume, menu, channels etc.). Try removing all of these switches (don't remove the remote sensor). Don't remove just the channel switches.

If you have a remote than you don't 'have' to replace them, only if you want to control the tv from the set itself. After you remove them see if you have the same issue. If so you may need a new control IC chip.

A repair shop will charge about $75 to replace the buttons. If you have the tools and knowledge than feel free to do it yourself. To remove mine, I just used pliers and was careful. However to replace them you will need a soldering iron.

Parental lock


Child Lock

Combos
--Should have original remote. Press and hold the power button for 6 to 10 seconds


Combo Model T25208, V-Chip Forgotten Password
If you forget your password, simultaneously press VOLUME down on the TV/VCR front panel and the 0 number button on the remote for a few seconds. This resets the password and you can enter a new one.

Combo Model 13TVR62, V-Chip Forgotten Password
If you forget your password, press STOP/EJECT on the TV/VCR front panel and MENU on the remote simultaneously. This resets the password, but not the limits you’ve set.
Televisions with Parental Lock Feature


If you forgot your password for this feature, press the following buttons on the remote, one at a time. (Note: You must be in the password entry screen) Press, Mute, Display,Clear and Reset, this unlocks parental controls and you can now re-enter a new password.
OR TRY THIS..
Press and hold Menu on the TV AND volume down on the remote for 3 seconds. Nothing will appear on the screen, and the Parental Controls will unlock, and you can re-enter a new password with the LOCK PARENTAL CONTROLS

CTC169AU
Channels that have been locked can be viewed only when the PARENTAL CTRL function is set to OFF. This can only be done with the remote control-it can not be changed with the buttons on the front of the TV.

Therefore, after you turn on PARENTAL CTRL, you simply hide the remote control so that your children can not watch the locked channels. The locked-out channels will remain unviewable even if the TV is unplugged or the channels are autoprogrammed again. The only way to view locked channels is to use the supplied remote control to set the PARENTAL CTRL function to OFF.

The PARENTAL CTRL and the CHAN CTRL functions work hand-in-hand. The instructions below will first tell you how to turn parental control on or off with the PARENTAL CTRL function and then how to lock desired channels with the CHAN CTRL function.
1. Repeatedly press MENU to select SETUP MENU, and then press + or - to display setup functions. Repeatedly press MENU to select the PARENTAL CTRL function. . When this function is set to ON, PARENTAL CTRL is activated and any channels you locked with the CHAN CTRL function will not be viewable. . When this function is set to OFF, PARENTAL CTRL is deactivated and all channels are viewable.

2. To lock channels, press the MENU button to select the CHAN CTRL function. Select a channel you want to lock by pressing CHANNEL up or down. Then press +. The CHAN CTRL setting will change from NORMAL to LOCKED when that channel is locked. To return the channel to NORMAL, press the - button. Repeat step 2 for each channel you want to lock. If the PARENTAL CTRL function is set to ON while you are locking out channels, each channel will go blank as you lock it. When the PARENTAL CTRL function is set to ON and a channel which has been locked out is tuned, the TV will display the words PARENTAL CONTROL to let your kids know you have locked it.

CTC185's
If the front panel function buttons don't work, (menu, ch up/dn etc.) but the functions work normal with the remote, enter the "Channel" menu with the remote and turn "Parental Control" off.

CTC203's
In the event you have forgotten your password, perform the following procedure:
Press and hold for 3 seconds the TV button on the remote while pressing the menu button on the TV.
This procedure will turn off the parental lock and erase the previous password .

Another Possibility To Try For Various Models: If TV's in the Parental mode and askes for a password that's forgotten, Press menu on the TV, select Parental Lock #4 on menu, then with the remote press Mute, Display, Clear, and Reset buttons in sequence.

TX808 Chassis
If Parental Controls have been set and you don't know the password, do this:
Press and hold the volume down and the channel up buttons at the same time for 5 seconds.
Now you can reset the password to 0000, and using that password you can now access the V-Chip menus.

TV's (Made by Daewoo or possibly Apex, ie. GE model 24GP653)
The factory default pass code of 6688 is also the override code, in case the owner forgets their pass code. If that doesn't work, another place in the owners manual says to push Function and Mute on the remote at the same time. Function is the top right button.
