DIY Telephone Jack Repair: How to Replace an Old Phone Jack By SJ Johnson

There are few things in life more annoying than going to make a phone call and finding out that your phone doesn't have a dial tone. Suddenly, you have to wait all day for someone come to your home and repair your line, and if you don't have a wire maintenance plan, you are hit with a steep bill. Fixing a telephone jack yourself can save you hundreds of dollars. Years ago, out of necessity, I learned how to repair my own inside wiring. Since then, I've saved hundreds of dollars.
Check for a Dial Tone
The phone company will take care of any trouble from the central office up to your network interface - that's the little grey box outside of your house. Any trouble beyond that point is your responsibility. To avoid paying the phone company a fee, you have to make sure the trouble is not inside your home. If you have a dial tone at your network interface, then the problem is your inside wiring.
Check all of your jacks. If only one jack doesn't have dial tone, test your phone to make sure the phone isn't broken. If that one jack still does not have dial tone, the problem is the jack.
How to Replace Your Jack
1. Purchase a new jack. I recently bought a new jack for $6 at Home Depot.
2. Unscrew you current jack from the wall.
3. Before you unscrew the wiring, take a picture of it or write down the connections. Even though most wiring is standard, you may have an usual connection, as I once had. By having a picture of the connection, you will save yourself a lot of time and aggravation.
4. Unscrew the wires. This will separate the jack from the wall.
5. If you have new wiring in your home, the wires will be green, red, black and yellow. The connections are:

6. If you still have the old wiring, you will find a blue wire with white dashes, white wire with blue dashes, a white wire with orange dashes, and an orange wire with white dashes. Here is the connection chart: Old Connection Chart
Green=white with blue dashes
Red=blue with white dashes
Black=white with orange dashes
Yellow=orange with white dashes
7. Connect your jack to the corresponding wires by securing the wires under the screws. Technically, you only need the green and red connections for a dial tone. The black and yellow connections are for dial tone on a second line. To see a YouTube.com tutorial, click here.
Once you have the new jack installed, check for a dial tone. If you have a dial tone, problem solved. If you still do not have a dial tone on that jack, then more than likely you have to call the telephone company. Here are some online resources: DannyLipford.com and Wire-your-phones.com.
