Hello, I am currently recapping some old Audio equiptment and thought I'd try to resurrect 2 Tivos with lifetime service. The issue that took the 2 Tivos out of service was loss of audio on both units after lighting took out our phone service. Picture & functions seemed intact, just no audio. After cracking open the case, I have found the same resistors fried just off the phone input jack. (see photo). I don't see any other signs of failure & don't know if this area would even effect the audio. I haven't found any schematics to give me resistor values, so I'm stuck. I'm no electronic engineer, but if this can be fixed, I'd like to give it a shot.
