I posted previously about this unit, but didn't get any replies, so I'm trying again in a new thread. My lifetime Tivo HD was randomly rebooting, and I confirmed I had the capacitor plague problem. I ordered capacitors to replace all of them, according to a previously posted list. 4 or 5 of the original capacitors were definitely bulging and/or leaking, so I know this needed to be done. After replacement, I measured the voltages under load, and the results were: red: 4.90V, yellow, 12.00V, orange 3.31V. I'm somewhat suspicious of the red, even though it is within the +/-5%, nevertheless I wonder about it.
Also, I took the opportunity to upgrade my current 1.5T drive to a 2.0T model. I did perform a full media test on the new drive before I ran WinMFS on it, which it passed with no errors. Everything seems to work correctly with the exception of it randomly rebooting every 1-2 days. It usually doesn't go much more than 2 days without a reboot. I have been monitoring the internal temperature, and it seems pretty consistent of a low of 44C and a high of 47C, which is in the normal range.
Yesterday, it rebooted while I was watching a recording. No other shows were being recorded at the time, and I didn't notice anything out of the ordinary when it rebooted. I double-checked the internal temperature immediately after the reboot, and again it was within the 44-47C range.
There have been times that we have been away from home for a couple of days, and upon returning, the unit was frozen with static on the screen, and did not respond to the remote at all.
I'm at my wits end as to how to troubleshoot this, and what to try next. I have taken the power supply board back out and gone over the soldering with a fine eye, but I don't spot anything obvious.
I'm open to any and all ideas, and would appreciate any suggestions.
(My wife is a TV show junkie, and we have tons of recordings, so I would be in the doghouse if we had to start over with a clean install, and lose all the shows.)
