THE CONNECTOR ON MY TV FOR MY CABLE BROKE OFF. WHAT IS THE PROPER NAME AND HOW WOULD I FIX IT? I BOUGHT IT AS A DISPLAY AND IT HAS NO WARRANTY

If the cracked portion is on the cable then you need to get the cable recrimpted with another connector. You can do this yourself but this needs a special tool. Ask your cable provider to get the proper connector reapplied.

well that is catastrophic failure. have the motherboard replaced.

had same problem virtually impossible fix if broke off if you have rca plugs use vcr thats what i did!

Yes if your cable box has RCA yellow, white, red, outputs on it and your tv has RCA inputs on it you can hook it up that way. It'll only cost you one set of RCA cables which are not expensive at all.

The HDMI cable was causing "Display connected non-HDCP compliant" error message to appear.
When I reconnected my DVD to TV using regular cable with 3 color connectors(i don't know what is the proper name for that cable) that error message no longer appears on my screen and I was able to watch my movie normally.

This is the best solution for your problem as a 40 year experience with wires etc. Go to the source of your cable signal connector . Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires. Vitally

Nothing appears on my LCD TV display

1 Ensure the LCD TV display is turned on.
2 Verify that all the cables are properly connected to the LCD TV
display, including the power cable.
3 Check to see if there is a blue or amber light on the lower,
right-hand corner of the LCD TV display. A blue light indicates
the LCD TV display is on. An amber light means the LCD TV
display is in power save mode.
4 Ensure the proper source is selected in the Input Select menu.
See "Input Select Menu" on page 24 for more information.
5 Reconnect any devices that are currently connected to the LCD
TV display. If you are using multiple devices, connect and test
one device at a time.
6 Connect another device that you know is working properly.
7 Reset the original factory defaults. Press Menu on the remote
control, select Setup, and then select Factory Reset.

Problem Possible Solution No sound

1 Ensure mute is not turned on. Pressing the Mute button on
the remote control turns the mute function on and off.
2 If only certain LCD TV channels do not have sound, then you
need to correct the Input Select menu in the TV Menu (see
"Input Select Menu" on page 24).
3 Verify that the audio cables are firmly connected to both the
audio input connectors on your LCD TV display and audio
output connectors on your devices. Ensure that the cable colors
match the connectors colors.
4 Also, ensure that the audio cables are connected to the same
row as the video cables. See "About Your LCD TV Display" on
page 5 for the location of the connectors.
5 Reconnect the device using the same type of connector. For
example, if you are using the composite connector on the
bottom, try connecting the device to the composite connector
on the side of the LCD TV display. See "About Your LCD TV
Display" on page 5 for the location of the connectors.
After you connect the device, change the input source in the TV
Menu. See "Input Select Menu" on page 24 for more
information.
6 Connect the device using a different connector. For example,
if you are experiencing the problem using a composite
connector, try using the component connector.
NOTE: To connect to a different connector, you need the
appropriate cables for that connector. See your device
documentation for a list of supported connections.
After you connect the device, change the input source in the TV
Menu. See "Input Select Menu" on page 24 for more
information.
7 Test the device on a different TV.

you can try to get just the coax replacement , otherwise you will have to get the whole tuner, and the number for the tuner is right on the tuner , but just soldering in a new coax connector is cheaper
good luck and thanks!

The connector that just fell off when the cable was pulled will have to be replaced by a service center, Sometime the connector will just come out ot the solder joint and can be replaced. Sometimes it breaks off part of the circuit board, if it broke the board it is not likely that anyone will be willing to try to fix it.

Yes, it is worth repairing. Replacing the F connector is a very simple thing, and as long as nothing was forced into the hole left by the missing F connector, the repair should run about $40.
