Hello,
I have a Thomson 28vk25eg television that I've owned for a few years, and since this morning my TV changes channels on its own, and it's not coming from the remote control.
I wanted to know if other people have had the same problem as me and if so, how was it resolved?
Thank you in advance

The television that changes channels by itself is due to humidity affecting the manual controller. You need to unplug the connector that connects the buttons for scrolling through channels. Another solution is to clean the plate that controls the channels or to replace it with another plate.
Hello, I have indeed been experiencing the same problem as you since November 9th, even though I have had this television since 2001, and I don't know how to resolve it. I also have two spots that have been there for a long time, one green and one pink, on either side of the TV.
Hello
for the stains, just turn it off with the switch (not the standby), leave it off for a moment, and when you turn it back on, it should have disappeared (degaussing circuit only active at startup with the main switch). Otherwise, this circuit is broken = TV repair technician
For random channel changes, check if you have any sensitive touch buttons on the TV to change the channel (clean them with alcohol). Otherwise, also check if there are any power strips causing micro-cuts; otherwise, it’s a repair situation because there’s a malfunctioning microcontroller in the control board, but you won’t have access to that; it's the technician's area.
Have a nice day.

Not stupid what you say redkiller, sorry bernorenard, but I've already had this situation in my old apartment, my neighbor had a pretty big TV, with a super powerful remote control (you could even unlock cars with those remotes by copying the signal) and it was him who, by changing the channel, messed up ours, it's not nonsense, I'm not saying it's the case here but it exists, and since we moved apartments there's no more probl...
Hello
The infrared signals from TV remote controls do not pass through walls because it is a light ray invisible to the eye, and the weak light from an infrared LED in the remote control does not pass through walls either, just barely through a glass door without curtains. Now you're talking about a "scanner" (banned from sale) capable of transmitting and copying audio or radio frequency codes like car key fobs. Let's not get everything mixed up, James Bond!
Hello anyway
PS a "radio frequency" signal cannot interact with a sensor, only infrared signals from a TV can.

Well, Bernard, I promise you, my uncle had a TV with a remote that scanned all the codes of other remotes and also the cash register keys (back in the days of the 405). By the way, my cousin and I had a good laugh with that remote; I believe it’s about the old televisions like the Philips. My father-in-law has one, and the remote (pretty impressive TV, by the way) can scan others, and it works for both TVs in the house. No lies or exaggerations, JAMES BOND?!!!
Hello Gam
Sorry for the "007 irony," it's about the gadgets.
I believe you when you say that remote controls that capture and memorize other codes do exist. I have a Sony one that came with my hi-fi; it can start the CD player, the amplifier, and the TV for the VHS recorder—it just picks up the essentials (play and direct recording). There are also universal remotes sold that pick up basic codes from TVs that will deduce (key) all the "commands" to memorize for the specific TV. What I meant to say from the start is that infrared signals don’t pass through walls; you can just try putting your hand in front of the lens—it won't pass. So, what about the neighbor? For a long time now, all consumer TVs have been using coded infrared signals. It's cheap to manufacture and is "secure" because it doesn't reach far. I mentioned in my first response that apart from faulty electrical contacts (defective power strips), the issue with the TV changing channels comes from a small "management board" for the commands and the touch-sensitive buttons of the TV (this is common with Thomson). There can be bad soldering, which is common, or a "millipede" that’s acting up (a small integrated circuit known as switching) – this is the repairman's domain because these spare parts are not sold commercially. So, you can rest easy; have a good day!

same problem on 28vk25es
since the beginning, appearance of greenish spots if the displayed image stays too long on a white background
a few months ago, the button to turn it off stopped working, I added a socket with a switch
and for a week now, the TV changes channels by itself and now it’s impossible to watch a program for more than 2 minutes. It's annoying, the TNT decoder is on the SCART!

Hello,
I have the same problem since this evening… the channels scroll down without me touching the remote, the program changes every 2 seconds or every 2 minutes...
I live in a detached house so I can't blame the neighbor...
I removed the batteries from the remote and it doesn't change anything...
I think Bernorenard is right:
“Intermittent channel changing, check if you have any sensitive buttons on the TV to change channels (clean them with alcohol), otherwise check if there are any power strips causing micro-cuts...
I cleaned the sensitive buttons with alcohol and since then it has calmed down... but I'm still cautious.
Thanks for the advice
For your information, the TV is a Samsung LE40C630."
