Just bought a new TV (Toshiba 50” U2963db ) and have connected the hdmi cable to slot 1. When we turn on the TiVo box, we get the Welcome screen and “Starting Up” screen... then nothing! The tv tells us we have no signal and goes black. Have taken out the hdmi cable and tried it in a monitor screen and the TiVo is still working... just not on our lovely new tv! Have tried the “turn off and on” option and made sure all cables are secure, but no good... Any suggestions or help gratefully received.
