Question about Televison & Video
I have plugged the new tv into the same coax cable as my old tv and it is saying it has no signal - why?
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----

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.

SOURCE: screen says no signal. when
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!

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.
