Default Why does my antenna not work anymore?

I just bought a HDTV and now I can't get any local stations at all. My antenna worked just fine with my old tv and I used to be able to get about 7 different channels. Why won't the new HDTV show any?
Please help. I'm so frustrated.

Your old TV probably had an NTSC (analog) tuner. Your new TV may have either an ATSC (digital OTA) tuner or possibly a QAM (cable) tuner.
Hopefully it's a digital OTA tuner. You need to make sure you are following the directions in your user manual to scan for stations.

Analog stations and their digital equivalents are on different frequencies, sometimes one is on VHF and one is on UHF, and transmit at different power levels. Some digital stations use low power and might not go full power until the analog stations go away in 2009 (interference problems).
What TV do you have, what type of antenna, and what is your zip code?

Yes, my old tv had an NTSC tuner and the new one is supposed to have both the NTSC and ATSC. I'm not sure about a digital OTA tuner, I hadn't heard of that before and am not seeing it on the specs. I scanned for stations just like it says and after doing it several times it finally came up with like two but those blink in and out and are really bad. I have my antenna in the same place I had it with my old TV. And used to get channels in nice and clear.

The TV is a OLEVIA 527V and the description under TV Tuner says "Combo RF (NTSC/ATSC) Tuner x1, the antenna is a Philips MANT510 VHF/UHF/FM, and my zip code is 23883

Thanks so much for replying and for your help

The ATSC tuner IS the digital OTA tuner. I am not sure how your sets options look when scanning. But on my HDTV, when I chose to scan for channels, I have the option to scan for cable or air. Make sure you use the air option, not cable.

Mine is the same and I have selected it for air. We might just have to try an outdoor antenna. Its just so annoying and doesn't make sense how my old cheap TV worked just fine and this one you can barely see a picture on the two channels I have managed to sorta get.

Arrow Input switch/scan

Melitak,
1. Verify your 'input mode' is set to "Tuner"
@ page 29...... switch 10

2. Then 'scan' for channels.
@ page 40.

I think I have it all set right. Just scanned again. I found 4 analog cannels this time... no digital. Blinked on to one of the cannels that it supposedly found with a bad picture and blinked off and says no signal. Another one stays on for once but it has a shaky picture and lines traveling up through it. Does that just mean its a weak signal. Is it possible my old TV had a signal booster on it and I need one for this TV? Actually come to think about it I used to run my antenna through my VCR. Maybe that had a booster on it.

I checked antennaweb with your zip code and it basically tells me you should not be receiving ANY digital stations with an indoor antenna, all the stations are rated "blue" or worse. Even the analog stations are no better than "blue". Pushing your height up to 200ft moves the stations to "yellow" but unless you are in a good reception area an indoor antenna is unlikely to give you much at all. Are you saying that in the same house with the same antenna your old TV gave you good analog signals? Which channels?

I must have just been lucky with my analog channels with my old tv. I used to get 27, 33, 43, 49, 15 clear and 10 and 13 with some static.

But an outdoor antenna was the answer. I went and picked one up and it changed everything. All I did was put it outside our window and it was like magic happened. I did another scan and I got so many channels I was shocked. I didn't know there were so many out there for free. I'm even getting them from as far as Richmond (60miles away) . Either the antenna is really good or we put it in just the right spot. It is a Philips MANT940. What a difference. Okay I like my HDTV after all

Thanks everyone for your help.

It's amazing what the difference is between an outside and an indoor antenna. Or even the same antenna, just placed outdoors.
Your antenna is supposedly UHF-only so you might have a problem with WVEC-DT after 2009 when it moves back to VHF-hi channel 10, but you can worry about that when it happens.

The Channel Master 4228 is one of the best UHF TV antennas and it has 6dB gain on channel 10.
