TV going through channels continuously


Try a reset. Different models do it different ways - but most require either unplugging for 5 - 10 minutes and plugging back in - OR - press and hold the power button on the TV for 20 - 30 seconds. You may need to access the Set Up Menu and perform the RESET from within one of the menus. Good luck!

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

Why does my RCA TV cycle through channels on its own?


this is the same type of problem happening with other rca models and I know it is the EPROM CHIP but why this is failing is either because of design flaw , dirty enviroment that they were made in , to much voltage or current to the chip or too much of a draw from the chip causing it to fail . Or even a random frequency from the IR sensor or its circut I'm still investigating and testing.
leave the tv unplugged for at least 3 weeks durring this time resolder any solder that don't look good , I did this and it lasted for about 6 months(always plugged in to the wall) before it started doing it again. model # 27v412t

Channel keeps changing


It sounds like a stuck button or switch. What happens when you hit the channel DOWN, does it still keep scrolling down?
Is this with or without the remote?
Have you tried it with the remote and or the TV?

Let me know whether you are changing the channels with the remote or the buttons on the tv and I can try to give you a couple more suggestions.
