It's too hot in Louisiana to do anything else but stay in with the A/Con. Thanks for the info. Tim in Baton Rouge...
If the problem lifetimed unit and the other one are both 648250s, I'd advise not cannibalizing the other one but saving it for a possible crypto chip transplant from the lifetimed one.
The TiVo Service Number, to which the lifetime sub is tied, is contained in the crypto chip, and if you move it to the other 648 board, you move the TSN and it never knows it's not where it always was.
If you aim the back of the motherboard at your stomach, then the antenna and cable inputs are in the near right corner.
To the left of it are the 2 cable card slots with the eSATA port in between.
Go straight to the front of the unit from the eSATA port, and at the end of the cable card slots there's a quad flat pack that says Atmel on it and another quad flat pack just beyond that with a paper label on it.
The one with the label is the PROM and doesn't need to be moved if you aren't using a hacked PROM, and the one that says Atmel is the crypto chip.
You could swap crypto chips between the units, giving you a working lifetimed unit immediately, and then troubleshoot the other one at your leisure.
Would you want to pay postage on a parts board?
