No front lights post mod

Sorry to revive a year old thread, but how did you get on fixing this?

I've got the same problem, but the TiVo was working fine for 12 months before suddenly experiencing the same symptoms; no lights, no hdmi output.

I've reflowed all the solder joints around the prom and checked the soldering, still no joy

Providing you are getting +12V from the power supply on the yellow/black wires and +5V from the red/black wires (or thereabouts it does not have to be dead on accurate) then you are most likely still having a failure to read the PROM.

I've created a document that traces out every pin from the PROM to the nearest top solder point to help people ensure that they have continuity if that helps:

I've got a 400dpi version if you really need it but it is a BIG file.

Wow, that's a great document you've created for fault finding. Both the 12V and 5V supply are fine, so I'll check the PROM continuity using your document.
