Can a bad power supply cause picture issues?

We had a power failure (actually 2 of them) about 2 weeks ago, and now our original Tivo OLED Series 3 is having extremely bad picture quality. Every few seconds it completely breaks up and the sound goes too, virtually unwatchable. But programs recorded before the failure seemed OK.



We've been living with it, but it has gotten worse and worse of late. I was thinking that it was the hard drive, so did a kickstart 54 and ran the SMART tests, which all passed. But now the Tivo isn't rebooting consistently, and I'm getting the 'click of death' on occasion so that's pretty much a sign of a bad power supply. Considering that this is the original one with known capacitor issues I can't say I'm surprised. The question is though, can a bad power supply cause picture issues? I'll go ahead and order a replacement power supply from weeknees but do you think that will do the trick (hesitant to get a new drive if I don't need it, especially since we already replaced the stock drive with a larger one).



It just rebooted successfully this time, so I guess my other question is, if the power supply is going (clicking sound and no startup), can it be intermittent?



Thanks for any thoughts!
