My HDVR2 has a tuner that is gone/going bad. When using the particular tuner, I'm getting intermittent but heavy pixelation.

I took a look inside and found.


Those two caps 220mf 3.5w are significantly hotter that the matching pair in the other tuner. (finger test)

So am I too far off base thinking that those caps are being stressed and replacing them would solve my problem. They don't appear to have leaked or bulged.

They seem to be surface mounted, So I don't expect to have to remove the board from the chassis.
