Backlight Inverter Replacement

Has your lcd tv's picture stopped working? Are you getting sound but no picture? If that's the case, then you need to replace your backlight inverter. Backlight inverter replacement is rather easy, you don't need any technical skill and you don't necessarily need a technician to take on the job unless you are too nervous about opening up the TV and getting near its innards.

Here is how you succeed in backlight inverter replacement:

1. Place your TV face down on a soft surface, particularly a table with towels to protect the screen.

2. You'll need a Phillips screwdriver and a flat screwdriver.

3. Remove the back cover by taking out the screws and using the flat head screwdriver to push down the plastic clip that keeps the TV's shell closed. You may also need to use the flat head screwdriver to pry the casing apart. The casing is technically a clamshell casing.

4. When the TV casing is open, you will notice there are two boards. The backlight inverter is the smaller board. The two backlight connectors are on each end of the small board or both will be on one side (top or bottom). You will disconnect the connectors and then simply lift the board out of its place. You will then install the new board the same way you took the old board out.

5. Some boards may have a CNI Connector in addition to the two backlight connectors. This must also be carefully disconnected in order to remove the board.

6. Reassemble the monitor casing the same way you took it apart.

As you can see, backlight inverter replacement is simple, but there is always a professional who can help you out. Replacing the backlight inverter yourself is also more affordable. Enlisting the services of a professional may not prove to be as affordable in that they charge you for the parts and their time. They can charge hundreds of dollars to do something that you can do for under $50. However, there is the convenience and the peace of mind that they offer through their skill.

It is up to you what you decide to do based upon whether or not the price of your television makes it worth you giving backlight inverter replacement a try or allowing a professional to do the job.

One question, however, is if you need to use the same inverter that the manufacturer initially installed into the TV. The answer to this is that you do not. Other companies will manufacture inverters for TV brands and sometimes their parts perform better than what was initially installed into the television. The prices do vary, but you can expect to pay less than $100 for a quality backlight inverter.

So if you decide to do backlight inverter replacement on your own, you can do so for under $100 and within 30 minutes to an hour of your time. Although television models are different, the overall concept of replacing a backlight inverter is the same. Make sure you remove all connectors and put the new board in the same way you took the old board out. It is as simple as that.
