Have TV Questions? Ask a TV Technician
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?
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 understand, checked the Input button on TV itself as well?
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.

Select HDMI if there is cable box hooked into TV and you use cable remote to change the channels.
Hi, do you need any further assistance with this question?Thanks.
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 I would suggest a new replacement TV as this one is obsolete for current video devices so think about to invest repair money on new TV that would be equipped with latest video technology for sharp and vivid picture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.
