Hello and Welcome. My name is ***** ***** I'll assist you today. I'm sorry you're having trouble with it. I need additional info to troubleshoot the issue.

1- Could you please get me the model number written on back of TV?
2- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?
Thanks.

Thanks for the info.

Please remove the batteries from TV remote and check if it now stays on video input?

The batteries in the remote control?
TV Technician: Shahid, Technician replied 1 year ago

Yes, also check the Input button located on TV itself to see it might get sticky and causing continuous command to change video input, push Input button on TV itself a few times to make sure it is not sticky.

I did same thing

Goes to blue screen with rotating no signal sign
TV Technician: Shahid, Technician replied 1 year ago

OK, have you tried to unplug TV and cable box power cords from wall outlet for 10 minutes to reset, replug back in and check?
This is the last thing we can try on user level fix, if it doesn't work then I'm sorry it would be hardware related problem and either control button board or main board would be defective, control button board is where volume, channel, input buttons are located and main board is where main controller chip is mounted that controls all the functions of TV including video input switching. Please reply back with the result to proceed further.

Thanks.

Better to run off Dmi or cable?
TV Technician: Shahid, Technician replied 1 year ago

Select HDMI if there is cable box hooked into TV and you use cable remote to change the channels.

Well itso back to where it was now not working again...going to unplug everything overnight. That don't work best to replace the main board first? I see its alot cheaper then the control board...
TV Technician: Shahid, Technician replied 1 year ago

Sorry to hear that, yes, try to leave it unplugged for longer time and if problem persist then replace main board to see if it fix the issue. I would suggest a new replacement TV as this one is obsolete for current video devices so think about to invest repair money on new TV that would be equipped with latest video technology for sharp and vivid picture quality.

Please feel free to respond if you have any additional questions.
