The power behind your TV’s image comes from its LEDs. Most TVs have close to a hundred LEDs. They create the light that brings the image to life. 80% of TVs sold use LEDs to produce the light that displays the image on your television. The other 20% of TVs use a newer technology called OLEDs, which are similar to Plasma TVs. The LEDs inside your television are specialized; they must produce the correct wavelengths (colors) of light, so the colors on your screen are accurate. They should also have the same brightness throughout the whole array; you don’t want dark spots. They do the heavy lifting, and sometimes they fail. It only takes one LED to go bad, and the whole picture can disappear. Or they can fail, causing the color in your picture to change or creating bright/dark spots.

Call and ask us, What’s your tip to prevent LEDs from failing?

LEDs and Lamps are often used interchangeably, but this is incorrect. Look at our page on lamps. These are used in older televisions.

If the LEDs in your TV fail, our technicians have the experience and proper equipment to repair them!

LED Lens Failure

In side the screen the LED lenses have fallen off causing bright spots on this TV. This is an example of a TV we repaired that was experiencing LED lens failure. When the lenses detach from the LEDs, it causes multiple bright or “spotlight” areas on the screen. This issue is common in TVs that are several years old, as the adhesive that secures the lenses becomes brittle over time due to heat and normal aging.

There are two proper ways to repair this problem, depending on the condition of the LED backlight. If we see dark areas or spots with a blue or purplish tint, it indicates LED damage, and the entire LED strip assembly must be replaced. However, if there is no discoloration or dark spotting, the TV can be safely repaired by re-securing the lenses.

In those cases, we epoxy every lens, not just the ones that have already fallen off. This ensures uniform brightness and long-term reliability, preventing future failures and extending the life of the television.

LED Replacement In-Progress

This is a customer’s TV that we repaired. This photo was taken during the replacement of half of the LED backlight array, which clearly shows the difference between healthy and failing LEDs.

On the left side, the LEDs are producing a clean white light and are evenly illuminated. On the right side, the LEDs have a noticeable blue/purplish tint and uneven brightness, which are clear signs of LED degradation.

LEDs can change color output when the diffuser or filter material becomes brittle or separates over time, or when the LEDs begin drawing improper current as they age. These changes result in visible discoloration and inconsistent brightness across the screen.
