Nowadays it is almost inevitable to go through the technical service with almost any breakdown, but to be well informed and know what to expect, it is worth knowing the most common failures in LED televisions.
Many of these failures are also applicable to LCD televisions, but not all, since many are associated with CCFL lamps that illuminate the panel and the high voltage they need to operate.
And it is currently essential to go to professional hands to solve any problem that these appliances present that, without a doubt, boast more advanced technology.
Now, is your television failing? So, it is important that you know what are the five most common failures of best LED TV brand in India. Get to know them!
- They light up but the image disappears instantly
It is common for some LED televisions to turn on, but the images are not reflected on the screen, that is, the panel works, but the mechanism that illuminates does not. Why does this happen? The main cause is due to a failure in the inverter, a component that is responsible for supplying power to CCFL lamps.
This failure can also be generated by an irregularity in another point of the circuit, such as one of the lamps weakening, for example, and as a consequence the inverter identifies the drop in current consumption, causing the equipment to turn off by measureof security.
However, in both cases, the protection mechanism of top LED TV brand in India is activated in order to prevent further damage, disabling the lamps, so the image is no longer appreciated within seconds of turning on the TV.
- They don’t light
There are two factors that cause ignition problems. The first is a fault in the transformer or in the television source, which causes the current not to reach the circuits directly, causing the equipment to not respond.
The second corresponds to a larger circuit that causes the protection mechanism to prevent the appliance from starting up. In the latter case, the LED TV android is likely to project a visual code to report the failure.
- Disadvantages in the image
Apart from the aging of the CCFL lamps, which –in general- causes the brightness of the television to fade, there are other causes that can cause problems in the image, such as an anomaly in the LVDS system (which is responsible for carrying the signal to the LED panel) or a failure in the video processor.
- Lines in the image
Sometimes ultra-high definition LED TV may be missing a vertical pixel line. This usually happens for multiple reasons, including; Interference from a nearby appliance, but most commonly it is due to a fault with a transistor column or an irregularity in the LVDS transfer.
- Mosaic effect imaging
Perhaps this is one of the most common breakdowns in this type of television, and is mostly caused by some of the integrated T-Con board, although there are also cases in which it may be caused by a failure of the LVDS or firmware.
