Greetings. I lurk here alot and have learned much from you all.
A few years ago, I got a 3576. It is a J&R refurb. Love it, when it works, but had a HE&& of a time using it. Didn't like using it through the cable box once Comcast switched to all digital, too much hassle to remember to leave the cable box tuned to the right channel. It wouldn't pick up any clear QAM channels through the straight cable (no box), even with a signal booster (well, actually I could get the local PBS channels, but that was it). I set up an antenna in my attic and ran it straight to my 3576 - that worked fine for about two years and then the channels all started "pixelating". I though this was from a weak signal and pretty much gave up on the unit.
Along came a refurbed 513 from J&R. Works like a champ. Picks up all of the QAM channels through the straight cable that I read all of you guys talking about. Haven't even tried the antenna in the attic - haven't needed to. Life is BETTER, but the 3576 still bothers me.
Is it possible to have a "weak tuner"? Is there something I can do to fix it? Thanks to experimenting with the 513, I have pretty much determined that it's the tuner on the 3576, nothing to do with hook up or cableco.
