View Full Version : Failed socket job

EDIT: Nevermind. Started poking at the pins with my continuity tester and saw one move when I prodded it. Soldered it down then fired up the tivo. Viola, she works! Successful socket job using chipquik and a 12w iron :D

Looks like the prom that I programmed in the s2 dtivo using getprom works good as well as I just popped it in there and its showing the 'welcome powering up' message.

Time to join the "hacked tivo hd" club soon as I start mucking with the hard disk :D

So I just finished putting the socket on my Tivo HD, had no problems removing the prom, but putting the socket on was a pain. Anyways, thought I was finished and plugged it in, but it doesn't start.

Anybody out there got any kind of schematic so I can know where I should try testing continuity on each point in case one of them isn't on there good enough? Or perhaps a map of which pins should touch something so I can just start hitting points, and which ones might not matter so I don't need to worry if they don't contact anything?

The locations of things are from recent memory so there may be minor errors there but the connections should all be labeled correctly. The "names" of the resistors in the array are my own because I think that makes it a little easier to follow.

FYI - Pin 20 (labeled as B16) on the chip leads to resistor A17 - not B16.
