😳 SMART TVs QUE MAIS QUEIMAM E DÃO PROBLEMAS - TV NOVA, VIDA CURTA 2024 ❌

Summary

This video discusses the decreasing durability of modern TVs, especially in comparison to older models that lasted up to 10 years. It highlights issues such as poor longevity, with TVs often failing after just a year beyond the manufacturer’s warranty. The video also explores the impact of different panel types like D-LED and E-LED, revealing how thinner TVs with edge-lit LEDs burn out faster due to heat concentration. The presenter emphasizes the importance of researching panel types and user reviews to ensure a good balance of quality and durability before purchasing a TV.

Takeaways

• 😀 Modern TVs generally have a shorter lifespan compared to older models, with many failing within 1-2 years after the manufacturer's warranty expires.
• 😀 Older TVs, like tube TVs, often lasted over 10 years, while new models with advanced technologies struggle to last even 2 years.
• 😀 Extended warranties are commonly sold by retailers to mitigate the risk of defects post-warranty, but they can drive up the price of the TV significantly.
• 😀 Common TV issues include panel defects, power supply problems, backlight failures, and LCD issues, with some defects costing as much to repair as buying a new TV.
• 😀 A study from Rfings tested the longevity of various TV models and found that many encountered issues after approximately 3,600 hours (about 5 months) of use.
• 😀 Common problems observed during the tests were burn-in effects, loss of image uniformity, color distortion, and, in some cases, complete screen failure after 6,000 hours of moderate use (about 4 years).
• 😀 The type of panel in a TV affects its lifespan, with D-LED (Direct LED) panels being more durable than edge-lit E-LED models, which can overheat due to uneven lighting distribution.
• 😀 Thinner TVs with edge-lit panels tend to overheat more quickly because the heat is concentrated along the edges, while thicker models with backlighting disperse heat more evenly.
• 😀 Major brands like Samsung and LG continue to improve their TV models’ durability, with LG and Samsung working on enhancing product quality and longevity.
• 😀 It's essential for consumers to research TV models and read user reviews to ensure the product they choose not only provides good image quality but also has lasting durability.
• 😀 The video emphasizes the importance of subscribing to the channel to support content creation, reminding viewers that most viewers don't subscribe, despite watching the content.

Q & A

Why don't modern TVs last as long as older models?

Modern TVs tend to have a shorter lifespan compared to older models, such as CRT TVs, due to the complexity of their technology and features. While older TVs could last up to 10 years or more, modern Smart TVs often show signs of failure within 1-2 years after the manufacturer’s warranty expires.

How does the warranty affect the lifespan of modern TVs?

The limited manufacturer warranty, typically lasting 1 year, covers any defects during that period. However, after the warranty expires, many TVs begin to show issues, and consumers are often left with expensive repair costs. To avoid this, extended warranties are offered, but this adds to the overall price of the TV.

What is the significance of extended warranties for TVs?

Extended warranties are offered to consumers to protect against issues that arise after the manufacturer’s warranty ends. These warranties can significantly increase the total price of the TV, as they cover repairs or replacements, which are often expensive, especially when the TV has issues like panel damage or source board failures.

What are common issues that arise with modern TVs?

Some of the most common problems with modern TVs include issues with the power supply board, backlighting, and LCD screens. These defects can cause the TV to malfunction, resulting in costly repairs. The burn-in effect and screen discoloration are also common problems with certain types of panels.

What did the longevity tests reveal about modern TVs?

Longevity tests conducted on over 150 Smart TVs from various brands revealed that after around 3,600 hours of use (equivalent to about 5 months), many TVs developed internal component problems, such as power supply board issues and burn-in effects. By the time 6,000 hours were reached (equivalent to 4 years), some TVs exhibited severe problems, including permanent screen discoloration or complete screen failure.

What is burn-in, and why is it a problem for modern TVs?

Burn-in, also known as image retention, occurs when a static image remains on the screen for too long, causing permanent discoloration. This is especially common in OLED and certain LED panels, where uneven lighting can lead to uneven wear on the screen, resulting in visible, lasting marks.

How do different types of TV panels affect durability?

TVs with different panel types, such as D-LED, E-LED, and OLED, have varying levels of durability. E-LED panels, which use edge lighting, tend to have shorter lifespans due to heat buildup at the edges. In contrast, D-LED panels with full backlighting distribute heat more evenly, which can help prolong the life of the TV.

What role does the thickness of the TV play in its durability?

Thicker TVs generally offer better durability because their design allows for better heat dissipation across the entire panel. Thinner TVs, which often use edge lighting, accumulate more heat at the edges, leading to faster degradation of components and a shorter lifespan.

Which brands are addressing durability issues in their TVs?

Brands like LG, Samsung, and Hisense have acknowledged the durability concerns surrounding their TVs. While Hisense claims that none of their new models use E-LED technology, LG and Samsung emphasize their ongoing efforts to improve product durability, focusing on better materials and technological improvements to extend the lifespan of their TVs.

What advice should consumers follow to ensure they buy a durable TV?

Consumers should carefully research the TV models they are considering, paying attention to the type of panel, the manufacturer’s durability reports, and user feedback. Choosing models with full backlighting (D-LED) and avoiding edge-lit (E-LED) panels may help increase the TV's longevity. It's also essential to consider the manufacturer's reputation for quality and invest in a reliable warranty.
