TV changes channels/volume/source by itself

Hi,
Our LCD TV will sporadically changes channels, volume, source by itself. It can't be turned off using the power button, so we would just unplug the TV and plug it back on when this happens. We have eliminated the remote control as the cause of the problem and we think it might be infrared emission from the laptop, but the problem still persists after we turn off the infrared function on the computer. Is there a way to fix the problem? Thanks!

Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

SOURCE: TV Volume turns down by itself - Philips 29PT8319 Matchline 27"

Most likely the volume down button on the front of the TV or the switch that it activates is sticking. Should be an easy fix otherwise.

SOURCE: FPA lock settings, No remote, can not power on TV

If you forget your password you can reset it. Make sure the TV is off. Simultaneously press and hold VOL< on the TV?s front panel and CLEAR on the remote for approximately 5 seconds. Enter a new password next time you access the PARENTAL CONTROL menu. Front Panel Lock 1. From the PARENTAL CONTROL menu, press the up or down arrow to highlight Lock Fr. Panel. 2. Press the right or left arrow to turn on (box has check mark) or off (box doesn?t have check mark) front panel lock. Of course if you don't have a remote that can bring up the menu I don't know how this can be done.

SOURCE: Volume stuck maxed out

the intrenal switch that controls the volume up is shorted. you need to have it replaced. the short of the switch doesn't allow any other buttons on the set to work because the micro is recieving the volume up command. it's as if there is an invisible finger pushing the volume up button. the switch is a tachtile switch which is very inexpencive to repair about $50.00 total. if you want to do the repair yourself be aware there are voltages that remain in the set that can be harmful. 50% of the time the cause of these switches shorting is improper screen cleaning. some people spray glass cleaner directly on the screen, this is bad. the cleaner drips into the set and lands on the PC board where the buttons are housed. but I've seen the other 50% also which is hummidity, dust(not anyones fault this just happens), and simple switch failure. so becareful repairing it your self

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.

Impossible to change channels, turn TV on, Power and Opc blinking


go into programming mode and search for channels   it will do this automatically to find all antennae and all cable channels    if this is hooked up to a receiver box then only channel 3 will be found or used    also most tvs are computerized these days and at times it will need to 'rebooted'     unplug the power and wait 10 seconds and plug it in again    this may have to be done whenever you are locked out from changing channels or using the volume controls

I need to re tune my samsung tv but have no remote any ideas?


you can always use the button on your Tv itself.

ie menu = Menu
Channel up/down = take you up and down
volume = goes left and right.

follow these steps

Menu,
channel down button to CHANNEL
press the volume button along
channel down button to AUTO STORE
press the volume button to Start the scan.

right now you have your telly tuned in. What you could do it get an old sky remote off a friend/ neighbour. or buy from argos etc ( a lot cheaper then getting a replacement samsung one)

press the following buttons on the sky remote to program it to work with your samsung tv.

TV,
RED + SELECT
TV.
0060

try the volume if this works press SELECT to save this code if it doesnt press Tv then try the volume again. repeat this step until the volume works your telly. once it doest dont forget to press the SELECT button to save.

Now you will be able to change your volume use the number keys. if you also press the HELP button on the sky remote this will also change your AV / SOURCE I hope this post helps you out. When it does please leave a thumbs up for me Please

Mintex 37 inch wide screen. remote is working however cannot change channel, input source or volum. only turns tv off. The buttone on tv doesnot work connot change input source or volume


Check if the remote is in TV position, that is, because most of the remote controllers have the feature that you can program them for use with another devices. Make shure that one button that says "TV" in pressed and released once before you try to change any function on the TV.
