Re: qam tuner

For most cable services, you need their decoder box to have the digital and HD services.

For the Sony HD TV, you will get best results with an HD cable box, and use the HDMI cable interconnect with it.

Call your cable company for details.

Does the tv model sylvania tvk191 have a qam tuner?

If the TV is sold in the UK, then yes it has a QAM tuner.

All TVs have to be able to pick up Freeview to legally be sold as a TV in the UK. Freeview is the public name for the DVB-T service which is our Digital Video Broadcast - Terrestrial service. DVB-T is just the standard definition channels. DVB-T2 is the version of Freeview that includes HD as well as SD channels. The QAMs are the way in which the signal is encoded. But it's really a level of detail that you don't need to go to. It's sufficient to know that the tuner is ether DVB-T for SD only, or DVB-T2 to pick up SD and HD.

Does my tv model#VS 420LF1A have a digital tuner

Yes, the Vizio VS420LF1A has digital tuners (assuming the TV wasn't damaged or altered). It has both an OTA (ATSC) digital tuner and an unencrypted cable (QAM) digital tuner.

For more details of the specs, see page 66 of the following pdf: .

I hope this helps.

I just purchased a used Sony KDL-V26XBR1 that cannot tune the digital channels over our cable or any signal on the over the air input. Our Samsung, same vintage on the same cable can tune the digital...

Greetings - Your Sony has the standard tuners for a current HDTV, NTSC (analog), QAM (cable), and ATSC (digital/HD) broadcast..

There's something going on with the Sony TV. It's a pretty high end TV so it might have some additional features that require you to do something different (I doubt it) but make sure you've been through the manual.

If you didn't get one with the TV you can download a PDF version HERE.

Good Luck and Thanks for using Fix Ya.

My Brand New 40" westing

To get HD channel form your cable TV without using the cable provider HD tuner box but using your TV Clear QAM tuner (your TV has Clear QAM tuner, my TV also has QAM tuner so I do not have to use the cabel box, but my COMCAST does not provide may Clear QAM signals like they use to) to get the unscrambled HD, the cable provider must provide those unscrambled Clear QAMsignals for your TV to pick up the signalS.

Did you use the correct setup during the tuner setup to scan the availabel cable channel per user manual?

There are no more analog signals, the fcc has forced a change to digital,
remember the big thing for a year about getting a tuner, well if your in the USA.

Make sure that in the settings menu you are set for digital, read your manual
on how you can tell which signal is being picked up.

How can I connect an ATL850 8.5 in. LCD TV to a cable box?

You have a ATSC Digital tuner in your set which accepts over the AIR digital transmission. Your set does not have the ATSC QAM tuner to receive digital cable transmission. Those size sets are usually designed for outdoor use with an antenna and for camping ect.....Outside of that, go ahead and connect it and see what happens...Do auto program.

Can't get digital tv channels.

The W1700 is HDTV Ready but it does not have an internal digital tuner, it only receives NTSC coded signals, not ATSQ/QAM coded signals. In order to see tv in HD you will need an external tuner with component or DVI output that you can connect to the monitors inputs.

Maxent lcd

Your TV is an "HD-Ready" television. What this means is that your TV is ready to accept HD input from an outside source, but doesn't have the ability to produce the content itself. It is a monitor and does not have a digital tuner. Without a digital tuner (or for cable a QAM tuner) you will not receive OTA broadcast HD.

You need to purchase a High Definition capable set-top converter box. The converter box will have HD component out and may have HDMI out, either will feed your HD Ready TV.
