Acquiring Channel stuck at 89%

I have spent weeks on this Premiere with a 500GB drive, countless times of cable card pairing, guided setup and twice "Clear and Delete Everything". It is definitely not a tuning adapter problem, because I have two plus another working Premiere unit (320GB). Here are the symptoms:

0) Cable card is properly paired, no question there.

1) Without the cable card, I can view unencrypted standard and HD channels (over-the-air equivalents).
2) Insert the cable card, click LiveTV or Zoom, I the blue background screen with the "Acquiring Channel Information" message and a 89% progress bar forever (no change overnight).

This is different from "Acquiring Channel" stuck at 50% or 75% issue.

I mounted partition 9 of the hard drive, combed through the /log/tvlog file and found the following 4 lines. The working TiVo's log has no mention of "NpkBooting" and has "LiveTunerResult ALLOWED" instead of "DENIED". This is a galactic long shot, which only an anonymous TiVo programmer can diagnose. Am I lucky?

Thanks

Have you tried overwriting the drive with a "fresh" drive image?

Assuming "fresh" means an image not related to this particular TiVo unit, I have not. For that, I have couple of questions:

1) Where do I find such thing?
2) Will it preserve my Tivo Service Number (TSN)?

I would think TSN is burned into the ROM but want to confirm.

Have you tried running Guided setup again with the cable card installed and paired?

Normally, you run Guided Setup with the cable card later option and again after pairing the card.

Yes, I tried Guided Setup countless time, with or without cable card inserted, before or after pairing.

1) check Tivo Community Underground

2) TSN is on your motherboard.
a new image will require repairing the cablecard.

To debug the problem, keep TA off of the system.
(non SDV channels should work)

make sure your Tivo coax does not go through the TA and is split before the TA. ( the TA kills the signal ).

Check OOB SNR in DVR diag.
( settings -> account & sys info -> DVR Diag .... scroll down).

you may have too weak or too strong a signal....

check info against your other working system.
(should also check the cabecard menu for status )


If you think the image on the disk is the problem (not likely)
you can dup the working image on your other system and expand
with jmfs software on your current disk or another disk.

shamilian,

a) Without the cable card, I can see SDV and OTA HD channels (see my thread opener).
b) I have two sets of (TiVo+TA+CC), thus easy to eliminate TA problem by swapping TA.
c) OOB SNR is 2db, on both sets of (TiVo+TA+CC).
d) I have a signal amplifier installed by Time Warner before the sole cable coming into the house/splitter.

I restored a foreign backup onto the hard drive, finished a guided setup then a Clean and Delete Everything. None of it helped, still stuck at 89% when the cable card is inserted (properly paired).

My conclusion after 3+ weeks: something wrong with its cable card interface hardware. Unless I can have a TiVo programmer look at the tvlog file, this unit is dead.

I checked a couple of TiVos OOB levels, one is 37db and one is 75db.

The OOB is at 75Mhz which is lower than most of the other frequencies on most systems. Check that the amp works that low...

you can just try as an experiment getting rid of the SDV/splitter that should boost the level by 3db this may raise the level enough....
