HDMI input works ok. Hooked up external antenna. Did channel scan. It will only scan for analog channels. Has analog raster on screen. It has no information on menu page for digital channel scan.

Bad tuner or main board. It's always been hooked to satellite. Need antenna for stormy weather when satellite drops out. EPROM?

    Hi Dennis Rokezewski, we want to help you with your question, but we need more information from you. Can you please add details in the comment box?
    /from the user manual of this tv it can only hold one database of digital channels being the cable.
    page 9 important facthttp://tv.manualsonline.com/manuals/mfg/...
    you are most likely scanning on the cable option
    The external antenna has to be scanned on the air
    option
    But I think scanning on Air may wipe the Cable channels stored.
    do you have the air option ?

Do you have the air option in the scan menu see
http://tv.manualsonline.com/manuals/mfg/sanyo/dp42841.html
page 9 important fact cable digital gets wiped by air digital channels

You may be able to get around this via a digital hd tv decoder box and then have it on a hdmi input on the TV as a backup to the cable if you can't have both cable digital channels stored and aerial digital channels stored

SOURCE: tv not working

Can you confirm that you didn't have any input signal? My wife once accidentally pressed the reset button on the remote and the TV was stuck in this state. I tried to hook up an antenna to the digital antenna input and let the TV search for a channel. It did find a station and got out of the channel search mode, which was all I needed. Then, I unhook the antenna and continued to enjoy my DVD movie. I didn't check the manual. So, it's possible that there is a better solution. My TV was working fine and I think it just has a terrible user interface. I'm not sure about your TV's condition, though.

SOURCE: Unable to use PS3 on HD channel

1. Connect PS3 to your TV
2. Select the Correct HDMI input on your TV
3. Press and hold the [power] button on the PS3
4. perform setup.

These are the steps to setup the video output for the PS3, It is possible that it is set to a resolution that your TV does not support.

If this doesn't work, you may want to contact Sanyo to ask if they have some protection circuit for the HDMI input. Some manufactures TV's will deactivate(turn OFF) the HDMI input under certain conditions. Unplugging the TV or some other procedure usually turns it back ON.

SOURCE: problem using Audio 3 sound inputs for HDMI video

Normally this problem is simply a matter of selecting the correct default audio playback device in the Windows control panel (sound option).
Check the Playback tab and set the default device to either DVI or HDMI.

Check your set up again. Mine says the HDMI/DVI is HDMI 1 (and then connect the audio to the video 3 audio input).

I need a magnifier to read the label on the TV. You just need the only HDMI input that has (DVI) in front of the word Input.

I hope this helps.

Vizio d-series 32" smart tv find channels using my antenna
On the remote, press the "MENU" button to go to the "Menu" screen, select "TV Settings" with the arrow keys, and press the "OK" button. Then go to "Device Setup" and press "OK". Go to "Input Source" and press the arrow keys until "Antenna" appears, then press "OK".

Select the "Tuner" option and press "OK". You may see an option to scan channels. Select it and press "OK". The TV will scan both analog and digital channels and can take an hour to scan all. Just wait and watch the "Found channel" count. If it does not increment, your antenna may be bad or not connected correctly.

The Vizio tuner is good enough to find over 14 digital channels with a cheap $10 flat digital antenna taped to my window.

How do I program my RCA LED48G45RQ HDMI to digital channels
Several things to check. First go in the menu where u are doing the channel scan and see if there is a separate line that says digital and if so select it so it can add those channels. Next look also on the remote and see if there is a button that says ANT or Input and press it to see if selects the digital side. Next see how u are hooking up the set from either cable, SAT, Antenna, etc, and are u going thru the antenna connection/the screw on cable input. Cause if going thru hdmi or any other input will not allow u to scan channels. Next the tv may not have a digital tuner in which some new sets don't, look in owners manual and read on channel programming and it should tell u. Maybe something here will help.

I have a VIZIO E552VL TV hooked up to an Over the Air Antenna and want to MANUALY put in channels NOT AUTO SCAN
Not sure if your TV is digital or analog, but I think an analog TV does not have the ability to perform auto scan, so you may be able to manually input the channels. As a kid, my dad installed a rotary antenna, and as it rotated and TV pictures displayed on the screen, dad noted the specific spot on the rotary unit; and every time we turned the set on, we just pointed the arrow on the dial on the unit to where dad noted what the channel number was on the unit, and the antenna turned toward that direction, and the pictured appeared on the screen.

How to hook up to hd tv
Use the highest resolution connection your HD TV will allow. This will usually DR570's HDMI connector. Most all digital video devices have one or more. The DR570 has an HDMI OUT. Connect it to any HDMI IN connector on your TV. You will then need to set the TV's Input selection to the Input Number you connected the DR570 to. See your TV Remote or Manual.

The DR570 has three types of output connection options, in order of quality; HDMI, Component(Red/Blu/Grn RCA jacks), S-Video (circular connector), and composite (Red/Wht/Yel, where Yel is video and Red/Wht are left/right stereo audio). Red/Wht RCA Audio jack connections are required to be made on all Output types excepting HDMI.

Note, to get your Digital channels, you will need to toggle the DR570's DTV/TV button. DTV is Digital TV channels. TV is analog channels, the DR570 found on your Cable or Antenna RF input coax, after you have done the Setup/General/Channels/Scan (extended). Scan only finds analog channels. Extended Scan scans for both Analog and Digital channels found active on your Cable/Antenna RF connection.

Note also, the DR570 is not technically and HD receiver. The term High Defintion (HD) is reserved to mean 1080i or p resolution, the highest available. The DR570 is an Extended Definition (ED) 720i or p receiver. It up-converts its ED to fit an a 16:9 HD TV screen. You will hardly notice the difference on your TV, but it is the difference between watching a DVD Movie on a standard DVD player, like this one, as opposed to a full HD player like a Blue Ray.

How do we scan/program in local tv channels. We bought an external antenna, but get no picture. Typically, there is a protocol for scanning channels into the set. Model is Sansui TVS2746B, and the set was...
Okay, does this tv have a built in DIGITAL tuner? Most tv's only have an analog tuner. You can tell the difference while you are changing the channels. If the channel indicates 2.1 or 2.2 and so forth, it is on a digital channel mode. If you change the channel and it indicated 2, 3, 4, etc. it is analog. If it has digital capability change the input until you see 2.1, 3.4 etc. If you cycle through all the inputs on the tv like, input 1 (TV) input 2(DVD) input 3(HDMI) and so forth and you never see the digital channel you most likely do not have a digital tuner. You will need to purchase a digital converter which will convert it to analog and you can watch it by placing you tv on analog channel 3 just like the old vcr's. Hope this helps and please don't forget to rate this solution.

Hello, I am currently having a problem with my Audiosonic KM0767 Standard Definition Set Top Box. When we first bought it we wired up all the plugs and it worked great. We then moved onto Foxtel...
did you switch the TV's incoming signal to digital antenna? For the cable box it was probably set to cable antenna or analog inputs, not all TV's have automatic switching for antenna feeds. My Mitsubishi has 1 digital and 1 analog antenna input and the cable box will only work through the antenna input if it's the analog antenna input and it's tuned to channel 3 or 4, -(or through a seprate HDMI, PROSCAN, SVCR,or a yellow RCA plug input)- and when the analog antenna input is selected the TV will tune all analog cable channels that the cable service offers if a box is not used. likewise the TV will not tune any channels at all if it's set to digital antenna inputs. It will tune all local channels only when set to digital antenna inputs.

Hitatchi 42HDF52 only receives channel 5 and 6 on analog RF input
If you have tried autoprogramming and have found nothing it may be a bad tuner. Is your VCR is hooked up via coax or into a video input? If it is hooked up via video and is working but the coax connection direct isnt it will be a bad TV tuner. Easiest cheapest fix is to use you VCR to change channels or get a Digital Cable Terminal from you cable provider and hook it into video or compnent.
