New to Fios...QAM not working on Vizio TV

cassiefish · 09-13-2009, 03:24 PM

Made the switch from Comcast to Fios...I have 1 TV w/cablecard-it's great. Another w/tivo-it's great. A vizio in the kitchen-didn't want a box. It got all the local & several HD channels w/ comcast no problem. With Fios-only 1 channel...Tennis in HD. When I do the channel scan it stops at 26%. Verizon checked the outlet-it's fine. Vizio says its a Verizon problem & Verizon says it's Vizio.
Help!

fiosman, you obviously do not know what you are talking about, so please don't get inaccurate information.

cassiefish, I'm not sure why you are having trouble. Out of curiosity, how long have you let the scan go? Did it stop at 26% for like 5-10 minutes and you got tired of waiting because it was going faster before? I would suggest starting the scan and then leave the room for maybe like an hour (do something else) and then go back and check on the progress and see if it passed 26%. Other than that, I don't really know what to tell you, but you should be able to get more than one channel via the QAM.

I did a scan on my Vizio. It did take several minutes. Picked up about 15 channels.

FIOS IS cable . . . just happens to be fiber optic on the delivery network . . . once it goes through the ONT it's the same as any other cable system.

Just like cable TV. The fios is converted to a cable type signal and hooked up to the STB or TV directly using RG-6 wire with F connectors.

FiOS and cable are two different things. Cable upconverts some of its channels to analog so you can pick up channels on any tv (sometimes you'll get unencrypted channels at odd places, like 147.322). FiOS is 100% digital and almost all its channels are encrypted, so you need to have either a box or a cable card.

This is absolutely incorrect. FiOS TV comes over the same type of network as cable. They both use QAM. The only difference is while FiOS is 100% digital in every market, cable is slowly eliminating analog and switching over to full digital. Cable has had digital tiers for a while though, which is why you needed STB's for anything but the basic channels. Also, you do not "upconvert" a channel to analog. You convert the channel. It's either digital or analog. Upconverting refers to increasing the resolution to be the same as the TVs native resolution (downconverting is the same in reverse).

Shark2k, you seem to have the best handle on this subject, but raise a few questions. I get it that, after FIOS signals pass thru the ONT, you've got digital QAM signals passing over the house's RG6 cabling. In my experience with regular cable providers however, a direct connection of the RG6 to a set with a QAM-capable digital tuner (which most sets being sold nowadays have) will yield way more than just the "basic channels", as long as they're not encrypted.

So can anybody tell me how many of, say, Verizon FIOS's digital channels are encrypted and so one would need a box to view them? If FmrComcastRep is correct (almost all of them), then I'm not switching to FIOS.

Channels 2-50, your local channels in HD, and the music channels are not encrypted and are sent in clear-QAM. All national channels (with a few exceptions) and subscription services are sent in encrypted-QAM.

This is 99.9% correct. It's actually 2-49 as 50 is USA. That answers your question MPEG-0.
