Have TV Questions? Ask a TV Technician
Hello, I'm Shahid.Sorry to hear that you're having trouble with this but I'll do my best to help.
There is only one possible option is to see if input change is possible to either increase or decrease the channel numbers till you get last channel number like 00 and then TV might give you video input change option.
If TV doesn't give such option then I'm afraid you would need to get TV remote as there is no other way around nor the TV has input button among set of control buttons located on side panel of TV. Required remote control is available at following supplier..
I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page. Thank you.
