Could be a fuse in the unit or a bad powersupply i would have a estimate done on it before repair gets started as a newer tv would cost less if this was a major issue.

1. check fuse
2. check power supply unit

If you do not know how to do this would recommend you take it to the experts as there is serious high voltage that can be fatal inside, Please do leave postive feedback and ratings for your free answer today.

20FP420T FP lock on and can't select input no remote?


Do you mean the 20F420T? RCA doesn't have a 20FP420T as far as I can tell.

Unfortunately, you can't turn off the Front Panel (child lock) without a remote. All of the front panel Power button to turn off the set but not to turn it on. You need a remote that matches the Menu function. Press Menu, then use the Ch+/Ch- buttons to select Preferences. Press OK then press Ch+/Ch- to highlight FPA lock. Use the Vol+/Vol- buttons to toggle the lock function on or off. (Off lets the front panel work normally) Then press Menu repeatedly to exit the menus. A substitute remote can be obtained here: http://www.remotes.com/remotes/servlet/rs?a=Search&o=c&uid=0&m=20F420T&uuid=12994577706920 . This is guaranteed to work with the 20F420T . Most universal remotes should also work as long as they were programmed after 2006.

The manual for the 20F420T is available here: http://support.ttetech.com/RCATV/NewTV/Templates/SupportDownloads.aspx?NRMODE=Published&NRORIGINALURL=%2fen-us%2fproductdownloads.html&NRNODEGUID={35D79B02-4AAE-4834-BFD0-1124EA501FA2}&NRCACHEHINT=NoModifyGuest . Fill in the drop down menus for 20" and the model.

I hope this helps.

Using the remote control hand unit that came with the TV turn on TV. Then go to the set up menu. Locate the entry for Front Panel Lock (FPL) and select no. Once you have done that exit the set up menu then on the same remote push the "input" button while watching the screen. Push button once wait a few seconds for a picture to appear, if not then push the button again, continue until you have selected the input that provides a picture. Right now you are in the Front inputs you should look for Video 1 or 2.
