    I have 2 Roamios that are now barely used. They record some local cable access channels maybe 3-4 times per month. I currently have them kept in standby mode most of the time. I know capacitors with the series 3 was an issue. Is having the Roamio in standby about 95% of the time better for the capacitors in the long run? Or as long as the Roamio is plugged in, the capacitors are being used?

    I can only answer that if you can tell me what is purpose of the specific capacitors. There is a slight temperature drop in Standby, so that helps. I have a spare Roamio. I only apply power to it on weekends. I think you can safely continue your procedure.

    Better(Maybe), but not in any amount that would make a difference.

    The primary issue with the failing capacitors in S3 series units was not use or age, but that the capacitors themselves had faulty electrolytic compound in them which caused them to fail early, this has not been seen in Roamio or later units.

    Capacitors in question were part of the power supply in the S3.
    Roamio's, AFAIK, use wall warts for power.
    (not sure on the Roamio Pro, thus the AFAIK)

    The base Roamio (4 tuner) uses a wall wart and the Plus/Pro (6 tuner) have an AC plug for the internal power supply. I've had my Plus plugged in and running for 6 years with no PS issues (yet!).

    OK, I see. I guess Roamios are not the same design as some previous TiVos so can't really compare. I'll simply unplug as needed.

    Design isn't part of the equation, faulty capacitors are the issue and Tivo apparently learned their lesson and moved to better suppliers.
    Even then, the S3 units should never have had the issue since "capacitor plague" was known about in the early 2000's and by 2005 when they were designing the units they should have been aware to stay away from known bad suppliers. If you want to go on a google rabbit hole trip, capacitor plague and how it came about is quite interesting.

    Thanks! I thought I knew about this, but reading the rest of the story was fascinating!
