So, just modded another TiVo, no front lights on the panel.

The lights on the Ethernet port light up, the fan and disc spin up, tv screen is blank (no splash screen at all).

I've checked the power supply volts with a multi meter and all appears ok.

I've had a good look at the chip holder soldering and it appears to be ok.

Any suggestions? I'm guessing I may have to remove the holder and try again.
