The Flickering Dilemma: Repairing an LG TV Without Breaking the Bank


“Good evening, esteemed expert. My parents own an LG 47LB6100-UG television from 2014 that has begun to exhibit flickering issues following a recent power outage. Initially, it flickers briefly upon startup, then goes dark for approximately ten seconds, and subsequently enters a state of continuous flickering. I have verified the integrity of all connections and cords, which appear to be in order. The TV was also connected to a surge protector, and no other devices sharing the connection have been damaged. Could you provide any insights or recommendations for addressing this flickering problem? Given that the television has been reliable for nearly a decade and considering my parents’ current financial constraints, purchasing a new TV is not a feasible option. If repairs are impractical, could you suggest any affordable alternatives that offer comparable quality?”


I understand the concern regarding your LG 47LB6100-UG television’s flickering issue post-power outage. Flickering can be caused by various factors, including loose input cables, incorrect display settings, or a failing backlight. Here are some steps you can take to address the issue:

: Unplug the television from the wall for at least 30 minutes. Press and hold the TV’s power button for 15 seconds to drain residual power, then plug it back in.


Check for Software Glitches

: Perform a soft reset by turning the TV off and on. This can resolve issues caused by the TV’s operating system crashing or memory overloads.


Inspect the Backlight

: If the flickering persists, it may be due to a failing backlight. This would require disassembling the TV to replace the LED strips, which can be a complex process.

If you’re not comfortable performing these tasks, or if the issue persists, it might be time to consult a professional. You can find TV repair services that may offer free quotes or diagnostic tests to determine the problem and the cost of repair. It’s worth noting that if the repair costs are high, it might be more economical to consider a replacement.

As for affordable alternatives, there are several options available:

  • Streaming Devices

    : Consider a streaming device like Roku, Amazon Fire Stick, or Google Chromecast. These can provide smart capabilities to an older TV at a fraction of the cost of a new smart TV.

  • Budget-Friendly TVs

    : Brands like TCL, Hisense, and Vizio offer quality televisions at lower price points. They often have models that provide good picture quality and smart features for a reasonable cost.

  • Second-Hand TVs

    : Look for second-hand or refurbished TVs from reputable sellers. This can be a cost-effective way to replace your current model with a similar or slightly upgraded one.

  • In conclusion, try the suggested troubleshooting steps to potentially resolve the flickering issue. If repairs are not viable, consider the alternatives mentioned for a budget-friendly solution. Remember to weigh the costs of repair against the price of a new or second-hand TV to make the most financially sensible decision.
