Lot's of folks have reported very strange things a happening with converter box's. One thing we can be sure of , they were never designed for compatibility with older than dirt TV's.  |
Well lets see here, I did previously have a 59 uF capacitor (a 20 and a 39 uF capacitor in parallel with each other) in place of the 60 uF capacitor but then you had said that the capacitor needed to be 60 or more so then that's when I upped it to the 39 and the 47 uF caps.
Should I go back to the 59 uF cap?
I wonder if the converter box issue has something to do with how sensitive the tuner and IF is to switchmode power supply noise? Because I know the converter box works fine with my Meck TV strangly enough but then it might be because that TV isn't overly sensitive to outside RF interference such as that put out by SMPS.
