Have a HR21-100 this morning was watching a pre-recorded show and when i used the 30 second jump key several times the screen went blank ! The box shows all the lights on but nothing on the TV. So I hit reset which everyone know that sucks ! Have to wait for ever ! Now watching a show in Double play and when i reversed the 30 second replay to get back wer i was the screen goes blank again ! WTF No error codes nothing ! just a blank screen. Anyone else experience this ?
