I have over a two year old single tuner Tivo TCD 540040. While reconnecting it to a new LCD TV...I saw the "Tivo lost signal screen with the various suggested solutions screen..ie change channels etc". However it was very snowy and a loud buzz.. Then screen went to blue. Lost signal.

Tried this TIVO with other TV's and cables. No go.

No signal coming out of this TIVO.

While the green light is still comes on in the front panel...activating the remote does not cause the orange light adjacent to green... to flicker on also??.

Tried all outputs and nothing..and my LCD TV says "No signal/input"

I purchased a new power source and that too made no difference. The key clue would seem to be the lack of the flickering orange light next to the green panel power light. What would cause that. Do I need a new board or what?

Any suggestions?
