Tell us about yourself!
Sorry, but I have no idea what the stuff is. Looks like some sort of sillicone sealant (like the stuff I use in the bathroom...) but I can't say for sure. In any case, it obviously isn't essential for the operation of the TiVo, so likely can be left out...
@nghosh - That's a good match; same uF, same voltage rating, same temperature rating.
The main difference between capacitors will be in voltage, and tolerance. Never replace a capacitor with one of a different uF rating; and never use one with a lower voltage rating (higher is OK). You should also try to match the tolerence.
As well as voltage differences, we have different frequency spectra for broadcast. However, I think this is controlled in the software rather than the motherboard.
... with the tolerance, use a lower if necessary, but never higher. The tolerance is how inaccurate the rating is. See http://www.robotoid.com/appnotes/electronics-capacitor-markings.html
My awesome cyberstalking skills tell me that you're in the US (Massachusetts or however its spelt), so yours is likely to be the US model of the Series 3 -- I've been working on the Au/NZ model. It's good to have a list of the replacement parts required for the US model. Identifying any failed capacitors visually can be done the same way as with the Au/NZ of course - look for bulging or leaking capacitors to indicate failure.
Thanks for the information! I've only been able to open up 3 TiVos here, and they all had the same model power supply, but of course there will be changes as time goes on.Is your TiVo a recent Au/NZ model, or a US Series 3?Steve
I was also wondering if the RPi3 would do better - many of the sprite-based games do not run fast enough under RpiB, or therir sound does not work. I have not heard of anyone doing this yet, though. Maybe one day I'll upgrade my table to an RPi3 and if I do I'll post here.
