We have purchased a LG nano cell 75" TV in early September and we found that the brightness of the four corners are uneven, especially the top right corner, like there are two torches shining. This can be seen at night time, especially when we watch movie that causing the details in dark scenes cannot be seen. We reported this to LG customer service, case opened, photos sent, then no follow-up. We then reported this to the retailer, case opened, photos sent but they said they have to consult LG first and and LG will contact us. Again, no follow-up from LG. Next, we called the retailer again and they were also confused how come LG had not contacted us. Later on, we received a reply from LG saying that “this is normal”. They said the uneven brightness of the corners is normal, not a problem. Wow! Excuse me? We’ve been using TV for a few decades and never heard this is normal! Even an idiot knows this is a problem. After this, we talked to the customer service through Live Chat in their website and sent some photos (some more) showing the brighter corner in our TV. No matter I turned down the panel brightness to zero, the top right corner still has two torches shining on. The LG CS also agreed this is a problem but they have to let their troubleshooting team to check. Unfortunately, again, their team said “this is normal”. Wow…… so are all the TVs out there in the shops have uneven brightness of the corners? I couldn’t see any uneven corners in my old SONY TV, the screen worked so well. Is this a new theory? Is this a new breakthrough of TV business to have uneven brightness?

After the call, we received an email from the case manager saying “This TV is equipped with an LCD panel that houses the ‘ pixels’ the LCD pixels makes up the colors, the light emitting from the bottom of the TV is from its backlight component, this kind of technology is called ‘edge-lit backlight; the light is dissipated from the bottom on a thin film that illuminates the pixels to generate the picture.”…..

First of all, EXCUSE ME? I read from the retailer webpage saying that this TV is “Backlight type: Direct lit”, and from LG official webpage saying that it is “Backlight type: Direct LED”. What’s going on? Does it mean that LG provide fake information? Hey man, it is lockdown and we couldn’t view the demonstration of the real TV in shop. We totally rely on the information provided from retailer and manufacturer when we buy things online. How come the information is inconsistent? We bought a stuff that is not the exact stuff we bought? Excuse me?

Secondly, ignoring the fake information, we did research some materials about the edge-lit backlight TV and understand that an edge-lit TV will often have an inconsistency in the spread of the back-light across the entire screen. It’s reasonable, under the technology of edge-lit, that the edge would behave differently from the center. However, I believe at least the four corners should have the same parameters setting and should behave the same, same brightness. If the four corners have the same behaviour, I can easily turn down the panel brightness (backlight) to solve the bright corners issue. Unfortunately, since our TV has uneven (inconsistent) corner behaviour, the top right corner is still bright even though I turned down the panel brightness while the other three corners look alright. In conclusion, is it really NORMAL that the corners behave inconsistently?

I wonder if this is an individual case. If this inconsistency happens to all the TVs of this model, then I understand why the LG troubleshooting team said “this is normal”. If not, that means our TV is a fault, and LG can simply let JB Hi-Fi give us a replacement but they refused to do so.

According to the poor quality of the TV, the poor customer service, the poor quality of their troubleshooting team, I do not recommend a LG TV to you.
