I have a Premiere XL. Recently I've noticed an unusual problem: after watching a recorded show, when I return to My Shows or TiVo Central, the TV screen is blank. I can press select and I hear the TiVo select something, and if I keep selecting until the TiVo starts to play something, the playback is fine. But the TV screen was blank even though TiVo functionality works perfectly. I can go to Live TV, and the TV screen shows live TV just fine, then press the TiVo button and TiVo Central appears as it should. But this is a weird problem that I can't find an answer to. Again, Live TV works, playback of recorded shows work, TiVo functions perfectly, it's just the screen itself is blank. Any help?
