What causes TV backlight failure?
TV backlight failure is typically caused by a malfunction in either the inverter board, a part of the TV’s power supply, or the backlight lamp itself. In some cases, the failure may be caused by an electrical component, such as the power supply or a capacitor, that has gone bad.
If the backlight is no longer lighting up, the component responsible is likely the inverter board and should be replaced. A common symptom of a faulty inverter board is a clicking or buzzing sound when the TV is first turned on.
If the backlight is flickering or dimming, the issue may be with either the backlight lamp or a part of the power supply known as the buffer board. The backlight lamp, if it has malfunctioned, may need to be replaced, however, it’s important to identify whether the fault is with the lamp or the inverter board before replacing any parts.
The buffer board regulates the power supply to the inverter board and can sometimes cause flickering or dimming, so this component should be checked as well.
Ultimately, a technical expert should be consulted if you suspect there is an issue with the TV backlight because faulty components may be the culprit.
What is the cost of backlight on a TV?
The cost of backlight on a TV will vary depending on make, model, and size. Generally, LED backlighting on an average 42-inch LED TV ranges from $150 to $500, while LCD backlighting runs between $200 to $600.
However, some LED TVs are now coming equipped with full array local dimming backlighting, which can cost over $1,000. Additionally, the cost of backlighting replacement parts can also vary significantly.
For example, a single, Philips LED backlight strip can cost $20, while a kit of three LED backlights for a 32-inch Samsung TV can cost up to $80. Additionally, if the installation requires professional consultation and labor, it may add additional costs.
How do I fix the backlight on my LED TV?
To fix a backlight issue on an LED TV, the most important step is to try and identify the exact cause of the problem. Common causes include a faulty power supply, a faulty backlight inverter, a defective light guide panel, or electrical shorts.
If the backlight is not coming on at all, the most likely cause is a faulty power supply board. This board produces the electricity used to power the backlight, so if it has failed, then the backlight won’t work.
To correct this issue, the power supply board must be identified and replaced.
If the backlight is flickering or dimming, the most likely cause is a defective backlight inverter. This inverter produces the high voltage used to power the backlight, so if it’s not working properly then the backlight won’t get the voltage it needs to operate correctly.
To replace this part, the backlight inverter board must be identified and replaced.
If the television has a uniform black screen, it could be caused by a defective light guide panel. This panel helps evenly distribute the backlight, so if it’s not functioning properly then the screen will appear uniformly dark.
To correct this issue, the light guide panel must be identified and replaced.
Finally, if the backlight is turning off or on intermittently, it could be caused by electrical shorts. This is usually due to a faulty connection between components, or a damaged circuit board. To resolve this issue, a qualified technician should be hired to diagnose and repair the problem.
Overall, the first step to fixing a backlight issue on an LED TV is to identify the cause of the problem. Depending on the specific issue, the part that must be identified and replaced can vary. If the exact cause of the problem cannot be identified, hiring a qualified technician is often the best course of action.
