No signal I've been using this receiver for over a year for OTA HD programing. I tried connecting my cable tv line to the receiver and couldn't get a picture to come up. It wouldn't see any channels when I did the automatic memorize function. I then switched it back to the HD antannea and now it won't find any channels through there either. I tried a different coax line in case it happened to go bad durning this switch. The front display on the receiver says C-and the channel number. Is his correct. I don't remember it being a "C" before. Does C mean Cable? I can't figure how to switch it back to Air...

Yes 'C' means cable. You need 'A' for air.

How can I change the resolution to 720px and above on this television????

What is your signal source and cable type? If your signal is being transmitted by a composite video cable, you need to upgrade the cable to component video or HDMI. (The cable you use depends on the device providing the signal.)

Next you need to set the set top box to an HD signal, if it has that feature. The steps will vary depending on the source. Please add a comment with the source for specific steps. (If you have cable, internet TV or satellite TV, you may need to contact your provider to enable HD programming. Many services charge an extra fee for HD content.)

I hope this helps.

(The source really does matter. My DVD recorder only records SD content. Even though I have the TV set connected to the unit with a component video cable, I don't get HD signal from those recordings or from the Digital-to-Analog OTA converter box that feeds the recorder.)

My panasonic viera has just stopped working. I can play a dvd but not watch tv, It says no signal. I have checked all leads and none are loose. It worked yesterday!! What is wrong with it? Please help

What is your TV source? Is it OTA, cable or satellite? Do you use a set top box or a direct coax cable connection? If you have OTA, what antenna do you use?

Try the following depending on your setup:

For all, check if a lightning/surge protector has taken a surge and needs to be replaced. These are placed in the coaxial line to divert a surge that could destroy your electronics. Also try replacing the cables. Check exposed cable for damage.

For OTA, first check that your antenna is oriented to point to the transmitters in your area. (Outside antennas will sometimes turn in the wind; indoor ones can be bumped.) Try a new coaxial cable. If the antenna has an amplifier (or you use a splitter with or without an amplifier), try connecting the cable directly without the device. I've had several amplifiers fail and turn into signal filters (blocking all of the signal).

For any system with a set top box, make sure that the box is on. For satellite, make sure that your dish hasn't moved out of alignment.

To check if it is the Viera TV tuner or the incoming signal, try another TV at the same connection. If you have cable and another TV gets no signal directly connected to your incoming connection, you may need the company to fix the incoming cable. (Underground cables can be damaged by rodents or neighbors who dig without checking for utilities.)

I hope this helps.

I have a RCA D52W20 rear projection HDTV. This TV was purchased in2005. I cancelled my cable and I just hooked up a digital antenna but the TV isn't finding any channels. What do I need to do? I was...

HDTV indicates the number of lines that are shown by the TV. (HD means that at least 720 lines can be displayed in a given picture.) To receive OTA signals, you need an ATSC tuner (digital) of sufficient power (with a clear path to the transmitter) these days. The RCA D52W20 was released in 2002 and only has an NTSC (analog tuner). You will need a digital-to-analog converter to receive OTA TV (unless any low power analog stations remain in your area).

Please note that the basic digital-to-analog converters that were available with the government coupon back in 2009 were SD (480i lines of pixels used) units. HD d-t-a converters exist but are more expensive.

I hope this helps.

(the phrase "digital antenna" is meaningless; check with tvfool.com or antennaweb.org for the direction of local transmitters. TVfool.com will give more information on the type of antenna (indoor, outdoor, amplifier) that you will need to receive channels in your area. Antennaweb assumes an external antenna but is very conservative in the stations that it will indicate that you can receive. Antennas are given a color rating based on how far away the transmitter can be to get a watchable signal. Since digital signals are either enough for the tuner to interpret or you get a "no signal" message, you often need a stronger signal than was needed to receive a watchable analog channel.)

How do I change my pro-730 HD to a digital signal?

You need a set-top box with a digital tuner. (For HD, you will need an HD digital source if you have cable or satellite. For OTA, you need one of those HD tuners; the digital-to-analog converters available with the government coupon last year were SD units.) You may be able to use a computer with a USB or PCI card tuner. However, you may be limited to the VGA input on the TV unless you use a converter or have a video card that can output in a TV format. (I can't find the specs for the DVI on the TV to tell if it is compatible with the RGB of the default computer signal.)

If you are getting an OTA signal, you will need an appropriate antenna pointed at the transmitter. Use antennaweb.org or tvfool.com to find out the direction of the stations you should be able to receive. antennaweb is very conservative in the list it provides even though it assumes an outdoor antenna. tvfool gives more information on the antenna for each station in your area. Note: tall trees and buildings can block the signal even if you should get a signal. Digital signals are either enough for the tuner to read or no signal. An amplifier may be needed if you share your signal between several devices.

I hope this helps.

Im trying to connect my unit to my tv to record shows and i having trouble doing so please help i am hooking it up wrong

For OTA or CATV signals, you need to daisy chain the coax from the source (antenna for OTA) to the coax input on DVD recorder and then the coax out to the coax input of the TV. If you have a set-top cable box with an incoming CATV signal, it should be connected between the DVD recorder and the TV.

The unit can tune in and record 480i (SD) ATSC (OTA digital), NTSC (OTA analog), analog CATV and digital CATV channels.

A satellite receiver or a non-CATV cable box should get the incoming signal first and then have their composite video output (A/V) connected to the DVD recorder composite video input and then their coax (RF) output (if present) gets connected to the TV. For these, you would record from the IN1 or IN2 (press Select Input) instead of selecting a channel. Then connect the composite video out on the recorder to the TV's composite video in.

Digital signals are either enough to tune in or give no signal. So check that your antenna is correctly oriented for OTA.

Separately, you can connect the video signal when playing DVDs via composite (good signal) out and component out (better signal) out to the TV's matching input. For the component video, the sound is carried on a separate cable. Then set the TV to the input source.

In the case of wanting to watch a VHS tape while taping to a DVD, do not use the Component video source, set the TV to Input 1 (composite).

I hope this helps.

You're closed captioning is all jumbled up on Seattle's KIRO TV from my DISH network. The cc works fine on all other channels. Dish says it's a network problem. Any response?

The CC is provided to DISH (and all cable/satellite companies) by the network that creates the programming. Usually, live TV (like news, sports, etc) is the most jumbled because of the time it takes someone to transpose what is being spoken as it is being spoken. If this is a network that is available OTA (via antenna), verify that the issue is not happening when you are receiving the signal from somewhere other than DISH (if you cannot receive an OTA signal, try at a buddy's house that uses another cable provider). If the problem occurs via OTA or other providers, contact KIRO to have them improve their CC service. If it only happens when viewed with DISH, contact DISH, who will then resolve the issue with KIRO (usually a lag time in signal transmission from the provider).

So you are telling me I need a digital converter for this TV to g

Who was not watching the months of public service announcements? You need a Digital-to-Analog (ATSC-to-NTSC) converter box to receive over-the-air (OTA) signals in most parts of the country. You do not need one for most cable and satellite box outputs--they are NTSC or HDMI. Some low-power, typically religious, stations are still analog. Note OTA may be high definition (HD) or standard resolution (SD) but will be digital.
To get HD on your HD set you must have OTA (HD TV tuner, not converter), cable (QAM TV receiver), satellite (HDMI or 5-wire RCA),or Blu-Ray with HDMI or RCA.

I don't know how a program it, since you change digital.

So far as I know the HLN series does not have an ATSC tuner, thus no over the air (OTA) reception. You can probably still get a $40 coupon for an OTA ATSC to NTSC converter. Note that will NOT get you high definition (HD). With Dish you can get HD receivers that do get OTA ATSC both HD and SD. With Direct, no OTA AFAIK. With cable you would need a QAM tuner, not in your TV AFAIK to get clear channels as required for locals. Otherwise cable needs a Set Top Box for digital and scrambled channels although the standard definition (SD) non-scrambled channels work with your NTSC tuner. Too bad there seem to be no ATSC to 5-cable RCA or HDMI HD converters except Dish. -Ken

Combining output from dish home distribution with ota antenna

You should have your system setup in the following manner below:

You also will only be able to receive the HD locals with a HD OTA antenna. It is possible that you will need to turn the satellite off in this room to view the OTA's effectively.

Also you should use a splitter as depicted in the picture by the red boxes to combine signals of this frequency. The blue box is the diplexer on the incoming satellite feed and the black box is the seperator that most dual tuners use. If yours does not utilize this device you will have another cable coming from the outside of the house to the back of the receiver. The location of the ports on the back of the receiver in my diagram may differ in position on your receiver so obviously connect them to the proper port. I hope this ressolves the issue and there is no need to seperaate the signal at the remote tv as it will only be a duplicate of the same signal you have connected already as OTA and the TV2 backfeed are of the same frequency range.
