Sound but no picture using all of my ports

That is the part that contains the tuner.

Hi Patrick,

You must have a UHF / VHF antenna connected to the antenna input of the TV to scan for digital channels. Most new TV's have a threaded, round 75 ohm coax cable connection for this - but yours might even have connection consisting of 2 small screws to connect a 300 ohm twin lead antenna cable instead. Use which ever yours has.

If you are using this input for the input of a cable TV "set top box" (STB), satellite STB, or similar, you will likely only find a single analog channel (Ch3 or Ch4) after a scan as the scan will only find the output of the STB - which is usually on Ch3 or Ch4 - and not be able to scan the STB channels.

Additionally, the antenna input of the TV will only provide a standard definition picture if connected via coax cable from the STB. It will only provide a high definition picture if connected to a UHF / VHF antenna and a broadcaster is close enough for its signal to be received by the antenna. The way to obtain the best possible picture (high definition) when using an STB for tuning channels is to use an HDMI cable between the STB and TV. An HDMI cable will provide the very best picture and audio signals from the STB to the TV; all over a single cable and is the recommended practice.

I hope this helps!

Purchase your UHF/VHF antenna. The antenna can also be purchased at most electronic and retail stores. Consult your list from Step 1 and see how powerful the over-the-air signals are for your specific address. Purchase your antenna based on the broadcasting power you need to receive a clear picture on your TV. You might be able to get away with an indoor antenna if your signal strength is strong enough. If not, you'll need to purchase an outdoor antenna.

4 Install your antenna (or have it done professionally) according to the building codes of your area. If you must use an outdoor antenna, it is a good idea to have the antenna professionally installed. This ensures that it is properly grounded on your roof, not too close to electrical wiring and stable during inclement weather.

5 Hook the converter box up to your television using the cable that came with it (F Cable). Hook your antenna up to the converter Box. Turn on your TV and converter box. Tune your TV to channel 3 and press "Scan" on the digital convert box. Allow the box to scan for your available channels.

6 View your picture and adjust your antenna accordingly for the clearest over-the-air feed. You should only need to make adjustments once. If you are having a difficult time getting a clear picture, use a signal strength indicator to see where you receive the most powerful signal.

Couple of things.

• Are you on an antenna or cable/sat box?
• If you are on an antenna, the sub-channel of a local DTV station (22-2) was the only thing the digital receiver was able to pickup on the initial scan of channels.
• If you are on an antenna, rescan for available channels.
• If you are on a cable/sat box, and scanned for channels you probably picked up a like channel that is in the same bandwidth as 22-2. Probably not even a channel.
• If you have a cable or satellite box, hook it up to one of the VIDEO channels using either a Composite AV cable (Yellow/Red/White) or a Component A/V Cable (RED/GREEN/BLUE with RED/WHITE for audio. If you are lucky enough to have HDMI for your source, use that.
• Going forward, all of your changing channels will be from the SOURCE.

It sounds like there is some electrical noise interference that would not be "fixable". If though, we reconfigure the way that they are connected together, we may be able to avoid the noise.

Instead of allowing the antenna signal to "pass through" the 625 we will skip it.

After following the directions, switching between satellite and antenna will be done by selecting on the SANYO "Input 1" for satellite, and selecting "Ant" for antenna. K?

Try this:

From the 625 Tuner 1- using RCA cables (a.k.a. composite cables, or red, white, yellow cable), connect to "Input 1" on the Sanyo TV. To see composite cables go to http://www.wowvision.tv/settingsandconnections.htm

Next, remove the coaxial cable between the Sat box and TV. (Sanyo "Ant. In" port and 625 "Out to TV" port) Set that cable aside.

Now, remove the incoming antenna cable from the 625 "Ant. In" port, and connect it to the Sanyo's "Antenna In" port.

Finally, scan for channels and check for the presence of CBS.

Once verified, test the TV by turning off and on.

Turn on the satellite receiver and switch Sanyo to "Input 1" to verify sat picture.

I believe this solution will satisfy your needs. Please let me know if it doesn't work, and I will need to talk to you about signal strengths, again.

God bless,

Usually you need a decoder to receive "Cable" With your "Cable" usually you connect the Cable antenna, to the Cable "Box" form the "Box" to the Audio Visual EXTERNAL inputs, in the back of the TV. Now IF your TV can receive the "Cable" directly, then you would have to connect the Antenna, into the rear of the TV, now you would go to the "Tuning" section, and, the TV, would automatically "Search" for any available channels. They would then, be displayed at the end of the scan. Please find a user manual below, this will help you tune in, IF you can. If you cannot, you will have to get a cab;e "Box" and a remote. Hookup to the TV, from the "Box" to the TV, via, Audio and Video cables. You use the "Box's" remote to change channels and volume. You first must set the TV's Volume, & picture setting, the TV, is basically just used as a "Monitor" for the "Box". Hope this helps..

If I understand your request right, You do not have cable or satellite box.
You can not record from your TV. You use the TV as a monitor from the dvd/vcr combo box. What the box receives is what shows on the TV. So you will have to have a digital convertor hooked to the (antenna in) dvd/vcr combo box, (antenna out to the tv antenna in) Depending on the antenna you are using that is on the other end of your cable-in coax connection this will hook to your antenna in on the digital convertor box. If your cable is hooked up and operating correctly and directly to the tv that is digital ready you probabbly have a good picture. When the vhf/uhf signal was transmitted you could go from the dvd/vcr to the tv with no problem. But now that the signal is digital and the tv is set for digital the dvd/vcr will not pass a digital signal to the tv. Best suggestion, you have to get a digital dvd/vcr receiver. If you have more question please contact me.

You probably have to find your original remote to the set and go through setup in your menu. On most sets, there will be a menu item which will allow you to switch from Cable mode to Air mode. If you have no Cable connected, then you must set tuner in Air mode.

If you are using an external device to run on channel three, then try this:
Make sure device (rather it's a vcr or game console), is hooked up to your Antenna Input connector. Also, some of these devices will have a small hidden switch on back that says 3 and 4. Move the switch to 3 position. Turn on device. Go into TV menu and do a Channel scan. This should auto program any device hooked up to the TV antenna input jack to channel three.

Keep in mind that you may not receive anything by Feburary of this year without an HD converter box to tune in channels with and outdoor antenna.

hook up a 6 foot peice of coax cable to the remote antenna port and then attach a barrel connector and then use a larger antenna "bunny ears" basically to extend distance of uhf signal for remote
