Digital TV freezes now that the digital conversion is done

When I'm plugged into cable it's okay (still freezes occasionally) but I got an antenna and scanned the channels to antenna, and certain channels are freezing up or skipping every few seconds. I can't tell you how annoying this is. Isn't digital supposed to be better? What causes this and how can I make it stop?!

    Thank you! I'll see if I can get maybe a signal amplifier, which I was just told helped a friend with her signals. Your description of why the TV skips and freezes was great, thank you!

Hello,

Do you remember in the old days when you got bad reception and the TV would get snowy? That was due to the signal strength of the incoming signal was not strong enough. We with digital TV you can still have a situation where the signal is weak, since you are looking at a digital picture the video and audio are packetize, and being packets they are first fed into a buffer and then sent to the decoding section of your TV. Now think about this when the signal becomes weak and the data stream is corrupted to the point that the processor rejects the stream that data which is in the buffer plays out and the last thing in the buffer is what you see on the screen (frozen image on the screen) until the signal strength goes back to normal and the buffer fills up again.

How do you stop this, well that's a hard question since the buffer underflow is the result of signal degradation, the cure would be to prevent the signal from degrading. This can be done with the use of an HDTV antenna (too expensive), an amplified antenna (priced ok for some but still too pricy for most), a rabbit ear type antenna with an amplifier added (this will work for most people), or just a plain set of rabbit ears (dipole antenna). All of these are options that can help you.

I hope this helps

Thank you,

How do i connect marantz rs2252. To tv


Do you have an audio out or headphone jack on the TV? If not you'll need a digital TV tuner converter box that does. If you remember, these are the "digital conversion" boxes the government provided when the USA switched from analog to digital TV. They sell for $50 - $60, have a input for TV system (antenna, cable, etc) and analog outputs that will connect to your Marantz via the "Aux" input. Purchase shielded "RCA male to RCA male" connection cables at Radio Shack, connect "Audio Out" from converter box to "Aux In" on Marantz and you're done.

Tv freezes


You need to boost your signal somehow, get a better antenna. nothing is wrong with the TV, this is a typical Dropout when signal is low.

Ever since digital TV started, I have had a problem with my picture occasionally glitching/pixilating, plus the sound freezes when this happens and I lose part of the broadcast. I currently have an HD TV...


Basically you are not going to get good quality TV reception on an internal antenna unless you live very close to the transmitter aerial with no significant metal structures (including buildings) in the way. You may get a slight improvement by placing the antenna near a window and away from any large pieces of metal or other electrical devices, especially any with a large magnetic field (anything with a motor in it). You may improve the signal / noise ratio by making sure that you have good quality, foil screened (satelite grade) cable between your antenna and TV set.
If the building has a (shared) roof top antenna you might get a better signal, which can be boosted using an in-line signal amplifier from that - but only if it is pointed at the right transmitter. However, as you will be installing the amplifier close to your set it will (just like the amplified antenna you are using) also amplify any electrical interference picked up by the cable as it passes down through the building - including from cars outside.
However your best bet is going to be cable or satelite TV

Okay i have a digital labs 19" LCD HDTV/DVD and it works fine until you hook it up to an antenna cable, then it wont give channels when i auto scan. what should i do? buy a new cable or is it the tv


I have the same problem. Seemed to work fine with digital cable, but after switching to Dish Network, no luck. If I plug the AV cables (red/white/yellow) directly into the dish receiver, it works fine. The problem happens when I use it as a second TV connected via the RF cable wire. My only guess is that the dish receiver transmits the signal to the second TV via NTSC ... and the Digital Labs TV only supports ATSC and QAM. Hoping someone can confirm?

Durabrand DU1901 digital ready?


The digital Cable conversion only effects those who still get their TV channels through an antenna or rabbit ears. If you get it through a cable provided like Comcast, you SHOULD be fine. For more information, look at the FCC website.

Happy viewing :)

Digital converter box


A digital converter box will only allow an analog TV to to operate in analog when using a stick antenna... If you have cable or sat Tv then you won't need the converter because those companies already do the conversion for you.
If you have a HD Tv than by all means it will get HD without a converter using a stick antenna and several stations are available or will be available on cable and sat with extra fees...
Hope this helps!

Digital signal conversion


If you have cable TV, satellite TV, or FIOS, the coupon eligible converter boxes aren't needed and aren't useful with those services.
They gov't coupon converter boxes are only good for reception with a regular TV antenna or rabbit ears.

According to the specs on epinions.com, no, this TV does not have a digital tuner. So, if you use a rooftop TV antenna (not satellite dish) or an indoor TV antenna, you WILL need an ATSC to NTSC converter box. You need not wait until next year, however, as most U.S. TV stations are also broadcasting digital (ATSC) now.

No digital channels


Hi quinny 1982,

The first thing to check do is look in the manual on how to do a factory reset.

Once you've done that look at this page on how to check the signal strength the TV is receiving. Anything less than 50% and most tuners will not display a picture.

If the signal strength is okay then try another auto tune.

If your still having a problem then I'd suggest you you might have a faulty unit. However, a lot the time companies like to blame your reception area, TV Antenna (Ariel) or cable length or quality. Yes, old coaxial cable used for analogue TV is not very good when used with digital equipment (not a surprise)!

From what you've described, if you can only get a mono signal I'd be surprised it that's actually a digital channel.

Don't forget to check your Antenna connectors.

Hope this is helpful.

Best of luck.
