You've probably locked out that channel. Go to menu and add the channel. See if that helps.

RCA TV model F27252GY. Don't think I have original remote. Need to set to input or video channel to use my new DVD. How do I do this?

You can try channeling up or down to get to channel 99.Rca in the past has used this to get to the video input. If this does not work you can buy a universal remote. In most cases, after programming the universal remote the major functions such as channel select, volume control and input select will work.
I hope this helps.

Sometimes TVs get reset after a power failure in which case it may default back to the setting it was prior to the initial purchase.When this occurs some, all, or noneof the channels may be locked. Go to the tv menu and run a channel scan this should find all the channels you want however you need to ensure you are scanning the proper source such as cable for cable or antenna for an aerial outdoor antenna. If you have satellitte you may need to power the STB off using the button on the STB itself. If that fails it may be a line of sight issue such as dish being moved by external forces e.g. windor kids.
Hope this helps you.

Get a universal remote or go online and order a replacement original remote for your model. Then use the remote to enter the menu, unlock any child locks, make sure the set is in standard cable mode and do an autoprogram.
