All of a sudden both Remote controls don't work for tv? fine for DVD

Is the tiny plastic lens over the IR sensor of the tv fogged over from cleaners? Or if you can take the back off, find where the IR sensor connects to the chassis, and remove it and re-connect it - The plug may have absorbed moisture and caused a little corrosion. JTT

TV

You've probably put the TV in an illegal mode by the wrong r/c button combination. I can do that on my own TV by trying to go into teletext mode on a 'universal' r/c. It only half switches to teletext, the mode is displayed on the TV's chassis display but no on-screen display and latch up on all functions. Returns to normal after switch off but perhaps yours has over-ridden the default setting so stays even after switch off and on.

addendum If you normally switch the TV 'off' to standby , try unplugging the TV for an hour
