Not knowing if set is under warranty I would make the only simple suggestions I can:

If you have a box disconnect it and the TV from power for several minutes, make your connections with the unit or units involved not connected to power---after several minutes with things all back and connected power the set and or other units back and see what happens, cannot hurt and may help.

If the set is brand new and has a warranty contact where you purchased it---warranty usually is one year parts and labor---last resort would be to see if it works with a DVD etc connected to one of the rear inputs----a Cable box with those fittings can be usually got from the cable provider and used with a rear input----

SOURCE: No cable signal on 32" flat panel Olevia tv

When you write 'tuner,' do you mean the internal TV tuner or do you have a cable box between the wall connector and your set's input?

If you are connected from the wall to the set, then the sensitive circuitry (it may only tolerate a few volts max video) is damaged.
If your set was a couple of decades old, it might be fairly easy to repair.

If the set was damaged via the cable service, you may have some recourse unless your cable provider has seen fit to absolve themselves from liability, I suspect they have.

I do not know your set but it is not impossible that the video input circuitry for cable and antenna is on a smaller assembly that processes it before reaching the main board.
The latter has obviously survived since you still have the other functions.

HD TVs do have different cables, I went to Time Warner and swapped my regular box for an HD box, the cable ends are blue red and white, I believe. Also in order for my box to work on the screen I have to switch to "Component" instead of "TV". Hope I helped!

SOURCE: "No Signal" Message when using HDMI Inputs on 26" Proscan LCD TV

You MUST get HDMI Driver for your Video Card, it is NOT standard. You need to go to PC makers web site and download latest Video Divers for your PC, then you must set up Multiple Desktops, To do that you must first connect the TV, but leave OFF, connect up to PC, reboot, setup Video Card, turn ON TV, TV will have already been detected, On PC, Share the desktop, or Clone, whatever you wish, now reboot after saving settings. Now you set the TV for HDMI already and it should show you a desktop when chosen. You must select and setup TV, FIRST, then connect the PC. From then on, Turn the TV ON, then turn the PC ON, that way it will Always detect the HDMI port.

I hooked up my new Proscan TV to the antenna but it can't find any channels


You need to check the connection is tight from the antenna and also on the back of the tv. You may need to try another coaxial cable. Is your antenna powered, meaning does it have a power plug that needs to be plugged in? Is your tv an old crt television? You may need a converter box to be able to view digital channels. A signal booster may help you get more channels.

Your tv or antenna may be defective. You could try your antenna on another tv. If your other tv gets a signal, your tv's tuner could be bad. If the other tv goes not get a signal either your antenna could be bad. I hope this helps narrow down your problem.

MY ALBA TV SAYS NO SIGNAL EACH TIME i PLUG IT IN

It is possible that the cable to your antenna is broken somewhere. You have the right idea to start there.
It is also possible that your TV is looking at CABLE instead of AIR, or visa versa.

Setup proscan tv


Newer tvs have a lot of input connections ( holes) and can be very confusing. With out knowing what kind of plugs you have I will try to help as best I can. First ,if you have a coax cable hook it to the corresponding connector. The coax is a pencil sized cable that has a center wire and a threaded nut. It will screw onto the threaded connector on the back of the tv. If you have RCA cables these will be color coded yellow for video red and white for audio plug these into the corresponding connectors. There may be more than one set of these connectors and may be marked input1 or input2 etc.make sure to write down which input you plug these into.you may also have colorstream cables there are three green red and blue. Some of the newer tvs don't have inputs for these but if yours does plug them into the corresponding colors. Another cable you may have is a s-video cable this is a single cable that has a multi pin connector on each end. Again find the corresponding connector and plug this cable in. The newer cable is called a hdmi cable and is a cable with a rectangular end. This one cable takes the place of the multi-pin s- video cable or the RCA cables. It also replaces the colorstream cables. If you were able to connect all your cables up. Turn on the tv. You may get a blue screen that says no signal. Don't panic take the remote and find the input button. Pressing the input button changes the tv to the various sets of inputs on the back on the tv. Press the input button several times waiting in between each press of the button for several seconds untill you find the input you connected your cables to. If your connecting a vcr make sure you have a video playing so there will be a signal for the tv to find. I'm not sure what a PVR is, but make sure it is playing some thing when you scroll through the inputs on the tv with the remote. Hope this helps.

Most of the channels breaking up despite auto retuning


could be one of a few things,
low signal strength, aerial out of line with transmitter.
bad coax connections losing signal strength.
coax broken inside, or old and not low loss.
Get the aerial checked for direction, half a degree out of line over a few miles and you will lose a lot of signal strength, as will old coax (aerial cable) and if you are using an unshielded coax you could be losing signal strength through the cable itself. Replace the connecters and try to use a straight run of cable instead of having joins in it as these joins, even if using connecters, will cause a weak signal. If yiu are running more than one tv off your aerial, invest in a booster.

Just got a Sega Mega drive, connected to my plasma


Most old systems such as Mega Drive will come with an RF adaptor, which plugs into the back of the console and has a coaxial tip on the other end, to connect to the tv.

When you connect the coaxial end to the tv, you connect it to the round coax plug which is where you used to plug in your old cable tv hookup. It also might say Ant. or Antenna.

Turn on your megadrive and use your TVs input selector to change to either "antenna" or "tv" or "cable" input, or until you hit the input which displays your megadrive's signal.

Tip: use your TV's view options to change the input to a 4:3 or "not stretched" aspect ratio so that your old Fullscreen video games will not be stretched out wide on your new widescreen HDTV.

Good Luck!

Why won't my tv pick up any cable channels?


If you have the cable box connected through the coax or RF connection on TV. (from the wall to the input of the cable box and output of the cable box to the in or RF in on the TV). Then in the menu on the TV you need to select the input source. It will say cable(CATV) or antenna. You should be set on cable.

these are not cross compatible an rca hook up is a base band signal basically raw data, and coax(cable line) is a frequency with a carrier best suggestion I have is to buy a vcr with a coax out put and rca input that way the vcr can pick up the video signal then remodulate it onto a channel frequency and send it to the tv
