How to make your LED TV last longer

If your LED TV is a day old or a few years old you can add to the life of the set by going into settings and lowering the backlight setting from 100 (default) to as low as you can set it and still get a good picture. According to studies half of all TV service issues come from LED backlight failure, by lowering this setting you can add years of service to your set.

My lg TV of three and half years has a black screen with images flashin Intermittently. The sound is fine


What is the model number? If it is only 3 years old, I suspect you have a LCD TV with LED backlight. You quite possibly have a failed LED backlight.

Many LG TVs of this age are starting to fail due to over-worked LEDs in the backlight which create the white light that illuminates the LCD image.

The symptom is TV turns on and off ok, gets sound on the connected video inputs, but has an otherwise black screen with no video on display. You can try to operate the TV near a bright window with lots of sunlight and see if you can perceive a faint image on the screen. A flashlight is often not bright enough to be helpful.

Most of the time, an LED will fail as a short circuit and still allow power to flow through it to other LEDs that will still light up. If one of these LEDs fails as an "open circuit", or if several LEDs have failed in the same circuit, then the power supply detects a fault and shuts the TV down. If the LED is intermittent, you may have flickering. Think of having one light bulb burn out in a string of Christmas lights and having all the lights go out until the bad bulb is replaced... kind of the same thing.

Your TV circuits boards should be fine. In my opinion your TV requires a backlight repair which requires complete disassembly of the entire TV including disassembly of the panel which is a difficult process.

2007 visio tv will flickerimage on and off why wont the image stay on?


if it's a fast flicker, you could either have a backlight inverter problem or power supply problem. The problem with 32" sets Hannah is that they are not worth repairing these days as the prices have dropped like a rock. You can spend more fixing the set than buying a new one! The fact that its a 2007 would make me want to purchase new. Your TV is 7-8 years old and is at the end of its service life. Sadly, LCD TV sets were not designed to last as long as the old tube sets. 5-7 year life expectancy is typical. If I have been of service to you please sign my guestbook page @

A white horizontal line on a tv is an indication that your vertical circuit is defective. Very common for the vertical IC to go bad. The fuse in a TV set is only there to keep your house from burning down if there is a problem. Your set has a problem. In my area repair should cost you about 100 to 120$. Tube Tv sets have about 5 years of expected life. I would invest my money in a new LED set.
