Ok that tells me something is wrong with the source of the video and sound then. What is the source you are trying to play? Is it coming from a cable / satellite box? For example can you get a DVD to play just fine on the TV? That would be a different source...
Thanks please let me know, just reply to my answer here and I can help you out.
Sorry, I miss-read this post. I orginally thought it said your cable broke, meaning the coax that went to the back of the TV.
The coax input is more than likely a part of the main board. I am not a tv expert but as with laptops and input modules that break you have to soder the peice on or replace the whole board.
Easier to switch to a/v inputs as mentioned in Solution #1.
I could not find a spec sheet for your model but did find this for you to give you an idea on what is entailed in replacing a broken RF connection. This may or may not apply to your model, but here it is anyway. http://www.youtube.com/watch?v=S9v-dUyzdrk
I would suggest letting someone who is qualified in TV repair fix it.
Here are the service manuals for your Zenith. Download both and then extract to your desktop for easy access. I downloaded and extracted myself to make sure it was a working copy so you are good to go.

If this model has a/v inputs you could use them and if you're on cable (direct cable not cable box) you could use a vcr to change channels - or you could remove the tuner and resolder the "cable plug" (RF connector) if it didn't crack the tuner circuit board when it came off.
Hi,
If you are comfortable working with a soldering iron, a continuity (VOM) multi tester and a fair knowledge of electronic components, then perhaps you can repair the missing color red.
You have to open the unit, expose the small printed circuit board that is attached to the small end of the picture tube. There will be many components present but you will need to focus yourself on three (3) transistors that are bigger than the others sometimes with an aluminum heatsink. It is also possible that instead of 3 transistors you will have one power IC. In any case these control and provide the drive for the 3 colors of your picture tube: red, green and blue. One of them is either dead or suffers from cold solder to any or all of its pins/legs. You have to visually inspect the solder joints of these big transistors/IC and determine if any is dull in color, loose of simply not connected. You may even try the shotgun approach and solder each of the pins/terminals/legs just as long as you don't cross solder creating a short between pins/legs.
If this works, you're set, if not:
You have to check with the use of the VOM and determine which of the 3 transistor is defective. If you are familiar checking continuity of base to collector to emitter and reverse, again you're set, if not perhaps you check all three and compare which have the same reading from the same position and which is different. Pls keep in mind the transistors have forward and reverse bias readings. If able to determine defective component, desolder, replace and solder. If it were an IC, replace the entire pack.
If the above would make you uncomfortable, pls ask for the services of a qualified TV repair man and explain your problem.
Hope this works out for you and give you some ideas. Pls post again how things turn up, good luck and kind regards.

they have service manual and schematics - sorry had no luck with a free one but the prices aren't too bad.
Hope this helps :)
If the LCD light on your Zenith CD/DVD duplicator is on but it is not showing as "ready," it is possible that there is an issue with the duplicator's internal components or settings. Here are a few troubleshooting steps you can take to try and resolve the issue:
Check the disc trays: Make sure that all of the disc trays are closed properly and that there are no discs stuck inside the duplicator. If a tray is open or a disc is stuck, the duplicator will not be able to operate properly.
Check the power source: Make sure that the duplicator is plugged into a working power source and that the power cable is securely connected to the duplicator. If the power source is not providing enough power, the duplicator may not be able to operate.
Check the settings: Check the duplicator's settings to ensure that it is set up correctly for the type of disc you are trying to duplicate. For example, if you are trying to duplicate a DVD, make sure that the duplicator is set to duplicate DVDs and not CDs.
Reset the duplicator: Try resetting the duplicator by unplugging it from the power source for a few minutes, then plugging it back in and turning it on. This can sometimes resolve minor issues with the duplicator's internal components.
If none of these steps resolve the issue, it is possible that there is a more serious issue with the duplicator's hardware or software. In this case, it may be best to contact Zenith customer support or a professional technician for further assistance.
Is the tv blinking a code on the light in the front of the tv. If so go to manualslib.com input the model number and look up the trouble code in the manual for the tv.
Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. It has set-up code list & set-up procedure to many popular brand remote controls. One among it has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Pull up older posts. Search the sites by type in the brand name of your device in its search box at the right column of the display window. It will help you to find the details easily.

Do you have the remote? If you do, it should have a quit button for menus like that. The remote is either the MBR3457 or MBR3447. It's on eBay for $10. It is possible that both of them may work for your TV model.
A common practice in the TV industry is to include the size in inches in the model number. Often, a model will be made in different sizes, for example, z42pj240 may have a z50pj240 family member. They will use the same main circuit boards and remote controls. Check the list in your universal remote control manual for a variant like that.
