Question about JVC HD-56G886 56" Rear Projection HDTV
I have a JVC HD-56G886 TV (~6 yr. old) and I have been using an antenna connected directly to the ASTC jack to receive digital broadcast. The picture quality was great and we got over 20 channels OTA. However, it stopped getting any signal when I was testing a new antenna with the TV on. Nothing even after I switched back to the original antenna and performed ASTC auto scan. I also unplugged the TV from the wall and re-scanned but still got no signal at all, zero. Both antennas worked fine with another TV with built-in tuner. Could you please help? Thanks, Jimmy
My (unfortunate) guess would be the Tuner received a static discharge when you were changing the antennas... this time of the year is bad for static - if you're in a "Winter" climate.
Receivers have a very sensitive FET or MMIC amplifier right inside from the antenna connection to make it better for picking up distant stations.
However, this same "sensitive" amplifier is also prone to being destroyed by even a small static discharge... especially if the tuner had its power turned ON.
Sad to say, it's likely toasted... :-(
(I hope I'm wrong... but you have already tried all other possible solutions)

SOURCE: No OTA channels
This television has an extremely weak tuner. It is very sensitive to both ghosting (multipath) and weak signal conditions, which cause it's digital decoder to "error out". Coupled with this is the decoder's long set-up time (time to actually begin a decoded video stream after signal is selected)and you find that every time the decoder loses sync it takes several seconds to reestablish normal decoding. The net result is the possiblity that the tuner will be continually restarting and never display anything. An extremely directional antenna may help. Otherwise, find a good external tuner box and use that.

I have the same exact model tv...Love it...ATSC tuners is in definition an Analog tuner. As the broadcasting companies change over to Digital broadcasting before the deadline in Febuary 2009 more and more local or Non-Digital chanels are becoming obsolete. You would have to purchase a converter box for your tv if your not planning on getting cable. Another way to gois if you have an old cable line running through you house (no incomming cable) plug you tv into that jack. That also acts as a antenna. The sweet part of all this is that your tv do have a QAM tuner or Digital tuner built in just need that digital antenna to pair it up.
