Blonder Tongue on Roundy
I have Zenith ATSC converter with video output feeding BT. AM-550 goes to 3 TV's with splitter but only the Zenith 25cm-- has slow 3" hum bar runs entire screen from bottom to top. but OK with my other BT. AM-550. So I would think PS filter caps in modulator. But why only on the Zenith? The rest are Solid State sets. Has anyone seen this?
Thank you,
Perry
