Background...I have the S3, always been on OTA, two HDDS, running great for many years...until this November. All of a sudden, partial recordings for a few channels. Hit or miss, sometimes it records fully, other times, partial in the beginning, middle, or end. Other channels record fine, the family have noticed some have slight pause during playback, I don't know if it is related to same problem. Thinking it was the HDDs that were near capacity of recordings, I had the family delete shows to regain some space. That didn't help. Next step, ran Kickstart to test the HDDs, all clear. Then, I took both HDDs and put them on the PC to test with WD and Seagate diagnostics, ran the short tests, ran the long tests, all clear. Rechecked the anttenna connections, check the diagnostic in Tivo for the problematic channels, SNR in the low 30s, signals in the high 90s. I was thinking it may be too hot, and it did coincide with the dropping of leaves in the Fall. So I picked up a variable attenuator from Solid Signal and tested with the different knob settings. Lowered the signals to low 90, mid 80s. No help, still get the partial recordings. Looked for bulging capacitors, they look fine. As you can imagine, I'm at my wits, I don't know what to check next or if our S3 has reached it's end. I have two other methods to follow, switch out the data and power connectors on the HDDs, and completely divorce the 2nd HDD, format and re-attach. I'd rather not divorce it due to the recordings still on it, so I have been holding off. Any other less drastic ideas? Could it be the tuner(s), this partial recording issue is happening on only 2 to 3 channels. They all have signal 90 and up and low 30 SNRs.
