Is the Magnavox TFT LCD 17 MF200v/17 have a digital or analog tuner?

I believe it has an analog tuner (NTSC) only. The original remote is pictured here: . The TV is listed as having been available in 2004 from The manufacturer didn't have to include a digital tuner until 2005 for 36"+ models. For a 17" TV, they didn't have to have a tuner until 2007.

I hope this helps.

I have an older Sharp Aquos TV - model # LC-32G4U. I am trying to connect a digital antenna but it doesn't work. Anyone know if I need a separate digital tuner for this TV? Or what else might be t

There is no difference between a "digital" and analog antenna. Either antenna will capture the signal. What you need is a digital converter box to convert the over air digital signal to the older analog type signal your TV needs. You connect the antenna to the digital converter box, and the digital converter box to the TV.
Several years ago, the US government forced peopel to buy digital converter boxes or newer TVs that could pick up the digital signal. Either get a digital converter box or a new TV.

No problem, I just want to know if this tv has a digital tuner? It says it has a "digital comb filter". Is that the same thing?

A digital comb filter is not a tuner. It helps improve the appearance of digital content by splitting the luminance (brightness) and chrominance (color) of a digital video signal (DVD, or other set-top box). This filter is only needed when digital content is going to the TV over RF (coax) or composite (analog) inputs. has some details on the filter,

Please provide the model number of the TV for additional information about the tuner. Normally the tuners will be listed as NTSC (analog), ATSC (digital), Clear QAM (unencrypted digital cable) in the US. In other countries you have PAL (analog) or DVB-T (standard definition digital terrestrial) or DVB-C (standard definition digital cable) signals.

I hope this helps.

Do I need a digital converter box to recieve a digital broadcast with a Sharp LC-20SH4U TV?

Yes you need a digital converter box. Your model has an NTSC Analog Tuner. It doesn't have a Digital Tuner. This is why you need the converter box.

For example, many companies like Comcast or Time Warner or TCI etc used to broadcast Analog Signals through their wires. Now they have broadcasted only Digital Signals. This makes either your TV Obsolete as a Tuner or you have to get a digital converter so your Analog TV can receive the signal.

Depending on your service, it may be worth your while to get a TV with a digital Tuner.

Then again, it also depends on if you are connecting a box receiver to your TV. For example, if you have Directv or Dish, you would then use your standard Video/Audio or Composite Cables to transmit your signal OR your Out to TV Coaxial whichever works for your receiver. Some receivers have already built in converters . You should really consider all the factors to decide and determine it based on the type of service you have or want.

Does it have an analog tuner? You might need to get a digital tuner box because most TV stations have now switched over to digital broadcast. If you still have the old analog tuner in the TV set, you won't get any stations unless they transmit analog.

Not able to scan for digital OTA channels on a JVC LT-32X667 LCD

Seeing as it does not have a digital tuner in it, I would think this would be the problem, you will have to get a box for it.
