Chances are you've got your DVD player hooked to OUPUT jacks on the cable box, not inputs. I haven't yet seen a box that takes any kind of an input other than the cable line, but they will have RCA jacks for audio and video outputs on the back. So your cable channels are fine, but the DVD signal is hitting a dead end.
The only solution if your TV doesn't have RCA inputs for video and audio is to get an RF converter (around $10-$20). This takes the A/V signals from your DVD and turns them into a channel 3 or 4 signal that connects to your TV's antenna input.
The converter also has a connector on the back for the cable coming from the cable box, since you'll have to disconnect that from the TV. When the DVD player is off, the cable box signal gets passed to the TV as normal. Turn on the DVD player and the RF converter switches on; put your set on channel 3 or 4 and you'll see your video.
One final thing: The converter will need an AC outlet for its power adapter or power cord, so make sure you have a spare. If you don't already have your TV and DVD player connected to one, this would be a good time to pick up a surge-protector outlet strip. Then not only will you have enough outlets, you'll be protecting your equipment as well.
If this solution has given you what you need, please take a moment to rate it appropriately. And thanks for asking here!
Hi, there is a sparking sound probably because whatever your cionnecting it from is still on. So switch of the unit where the cable is coming from, maybe its froma signal booster? and plug it into your tv, also there maybe still current running through your tv so switch off your tv aswell. It is quite common for connectors to spark when the equipment is on because the connector is try to make contact and there is a voltage present. I'm guessing that the TV works fine once the connector is inserted in or hasnt your cable guy gotten that far yet?
As long as its not a large spark and the source which the cable is connected to is not a high voltage source, which I dont see any reason why it should be. Also check the grounding of the cable. Considering you have a cable guy installing the equipment I'm suprised they do not know whats going on.....
YOU COULD USE S-VIDEO OR A YELLOW VIDEO FROM BOX TO TV TRY THAT
sometimes if the tuner is not damaged then a technician can put it back on... the other option is to tune the channel through a vcr.. essentally bypassing the tv tuner and useing vcr tuner. hook the cable to vcr then using rca jacks yellow red and white connect it to you tv(if it has rca jacks ...most have them these days.. sometimes on front and sometime on back or even on the side.. tune your tv to that input(video 1 or something like that.. then using your vcr remote change channel...its not a perfect solution but it will save you the 130 buck most charge to repair that connector
Are you sure your cable coax source is broadcasting any unencrypted digital channels, and is the signal strenth relatively good? In the Channel Scan, you need to also specify the source/input type as digital, and be sure to use the coax connector marked DIGITAL Cable (or similar). Begin the autoscan--it will take a while as the TV tries to tune any/all digital signals--most of which, if you're cable provider is like 90% out there (interested in profits), this might take 15-20 minutes, and will likely end up in lotsa black non-broadcasting detections (placeholders for on demand content), but hopefully, you'll find a 1/2 dozen or so 'clear' unencrypted. If you know the channel of a KNOWN digital local, tune to it, even if the picture is not initially visible. The lock-on takes a few seconds and if a signal is weak, it may take a long while if it can lock on at all. Usually, you'll find your local PBS stations on unencrypted channels from your cable provider, along with major network tv stations (NBC,ABC,FOX,CBS), but it all depends on what the cable provider allows. Don't expect them to tell you what exactly is free either! Underground webs will list your provider, Google to find out what to expect, and don't expect what you find to be all accurate. If you're in a decent reception area, and have any sort of an antenna, you'd likely pick up some of the OTA HD broadcasts, maybe even with just a coathanger :), just to verify that your QAM/OTA tuner is functioning.
