Possible Tuner Problem?

Replace the hdmi cable. I've stepped on an hdmi cable and broke something internally and had similar issues.

Try changing the input device to something you are sure, works such as a DVD player. Look for any loose contacts in RC jacks/sockets/Cable. Look for jammed buttons on remote and/or on control panel. Try removing the batteries from remote and operating from the control panel of TV. If these are ok, Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

You just can't. Not without an external receiver.

Your TV is simply missing a piece of hardware - it is called TUNER - that can understand the signal that runs through the cable (or an antenna) and decode it into simple video signal.

So the only solution is to buy an EXTERNAL TUNER device (also called external receiver or external set top TV box).

Those are rather cheap compared with what they used to be, but if you care for an advice from professional it is: sell your TV and use the revenue towards the purchase of a new one. All TVs currently in the mainstream sales channels have that thing built-in.

Some of the older models that you will find on Craigslist (like yours) do not.

it is usually not a problem for users with cable TV because most cable TV boxes also have a built-in tuner. If you are talking about how to connect your TV to your local cable company then the right thing to do is call your cable operator and tell them you want a newer receiver that outputs standard composite (one yellow one red one white) or component (green, blue, yellow and white and red) - if your TV has the later.

Hope this helps. If it does please rate accordingly.

Count how many times it blinks. Sometimes the problem is coded in the amount of times it blinks. If you see a distiction between blinks, say like 13 then a pause then back to 13 more blinks, google solutions for a 13 blink standby for your tv and you might be able to find the soultion.

You need to have a set top box.

By law, as of March 1, 2007, almost all televisions should include a built-in tuner (called HDTV, digital, or ATSC tuners) that can receive high-definition programs over the air by simply connecting an antenna. Your HDTV doesn't have such a tuner, you'll need to connect an external tuner (or cable or satellite box) to watch high-definition programming. External over-the-air HDTV tuners currently cost at least $150.

You did not list which console you have and what type of cables it has.

Looks like your plasma has:
1 component
1 composite
1 VGA
1 S-Video

If this is an xbox360 or PS3 then you will want to use the component connection, but this one is already used by the cable tuner. Don't worry there is a solution. The xbox360 and ps3 output a higher resolution that your plasma can handle, so use the component with those systems.

If it is an older console, predating the xbox360, then use the composite or S-video connections.

Since you are short on video inputs, you might need a video switch. A switch with both component and S-video connections for future add-ons.

You can find them all over the web, or your local video store like walmart and best buy. Here is a switch i found on ebay that should work:

Make sure you buy extra cables, most of these boxes do not come with cables, so buy what you need.

I prefer video switches that don't require a power outlet, but it's your choice. Some of the powered switches, have remotes for the lazy people, but I don't need anymore remotes on my table, keep that in mind.
