Tivo HD (02-14-2023) TCD652160 Pwr Supply, Capacitor List

Replaced the capacitors in the Power Supply with these, proactively, some were swelling, but Tivo HD was still working. 

Soldering isn't my best skill, but I was slow and careful and got it done. There was a surface mounted capacitor or resistor very close to the through hole for some capacitors, so I might have considered cutting the existing leads and tagging the replacements to the old leads sticking up from the board.. but I desoldered and succeeded at replacing them. I left them standing a little higher than normal away from the board to help with possible cooling by air and heat reflection from the caps to the pc board and back to the caps. I did not use non-corrosive silicone caulk to hold them still.. its kind of expensive, but I did leave them widely separated to keep them from vibrating into each other. I think this is a risk with the heat and cooling cycles and possible physical harmonics, be that fan vibrations, hdd vibrations, or some other vibration from the caps themselves. The electrolytic caps have a fluid between the paste and the wrapped internal planes and expansion and contraction can possibly generate an internal vibration of the cap itself and have adverse side effects if coupled to the pc board or neighboring caps.

The Tivo HD is a Series 3, but there were two or three models in that series, and in the Tivo HD I have apparently there were two different power supplies.

If it helps any my Power supply had the following label on the Input Filter Capacitor

My read is -

Model No: YM-3081A OP AR

3Y Power: CP-1319R2

TiVo P/N: SPWR-00011-000 

These are clearly not related to the Capacitor itself or its value and voltage.

There are other markings on the pc board itself.


Installing Windows 7 and updating in 2023


I had to install Windows 7 to support some older capture hardware with drivers and editing software that only worked under Windows 7, no Windows 8 and no Windows 10.

I got a few unfamiliar errors.

The first was I mistakenly used a Windows 7 (no Service Pack) install ISO image and then when I tried to install Windows Updates I had saved manually.. I got one to install and then all subsequent said "Not applicable to your version of Windows)

You have to install with a Windows 7 with SP1 slipstreamed ISO to succeed at Updating it with saved Updates.

So Windows updates meant for Windows 7 with SP1 , barely, or will not work with Windows 7 with no SP1 installed.

Same thing happens if you use a Windows 7 32 bit ISO and not the Windows 7 64 bit ISO, but that's easier to recognize.. I think it might have even a more specific error message hinting at the architecture not being right.

Then once you are installing the Windows Updates there are several critical de-marcations that really should have been Service Packs.. but since the culture had changed they couldn't use old terminology.

01 - 2015 April Servicing Stack Update 

- windows6.1-KB3020369-x64

02 - 2016 April convenience-rollup (Windows 7 Service Pack 2)

- windows6.1-kb3125574-v4-x64

03 - 2016 July and August Update Rollup

- windows6.1-KB3172605-x64

- windows6.1-KB3179573-x64

04 - 2019 March Servicing Stack Update and SHA 2 update

- windows6.1-kb4490628-x64

- windows6.1-kb4474419-v3-x64

After all of this.. amazingly.. Online Activation "works"

Until now I had to activate using the phone app.. but apparently its a matter of certificates and algorithms for online communications.

There are other Updates, but for various reasons.. you might want to not install them since they start monitoring or nagging the user about Updating to Windows 10 or later.

You also need to consider using this for "a specific purpose" rather than "general purpose" since it will be less secure than other operating systems and no longer receives security updates.
