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.

Channels keep changing


Make sure there is no other remote control working simultaneously or with a key pressed constantly by mistake. In my case i found the air conditioning remote control with one key being pressed by my furniture next to my bed, it was causing that erratic behavior. As soon i realized, i stopped that remote control and problem solved. I hope this works.

Tv switching back and forth from three seperate channels, cant get it to stop on any!


The only thing I know of that can do what you are seeing is if something has spilled into the set and has contaminated the pushbuttons under the volume/channel buttons. If the Channel Up pushbutton has fluid in and around it then it can conduct and the microprocessor thinks you are telling it to go up through the channels. The only way to fix that would be to disassemble the set and pull out the PC board which has the pushbuttons on it and clean or replace them. If you do not have experience working inside TV's then allow a qualified tech to handle it for you.

After programming my new universal remote, the tv keeps changing chanels! wont stop!


you need to program your remote control. take the battaries out. and maually turn the tv on. then hit the source you want to view. for example, I want to control the tv set. I push, code search and hold it then push the source button and then release the source button and then release the code search button. now, aim at the tv and then keep pressing power button till it goes off. when the tv is off, hit return or set or something like that.( every remote has different calling for it but still the same function) it should work. try it and let me know.

Tv wont stop changing channels


ok, Sony had this issue on their early production. The problem you are having is called a leaky switch. The volume down switch on the TV is leaky. To fix this you must replace the switch. This part is called the switch block. Part number 1-473-549-21

Average cost $26
