LG5800 auto dimming.

Hi,

I've been trying to email LG for WEEKS, now, and their online email form doesn't work! Their chat service either!

Anyway... My LG5800 auto dims every time the screen goes from a dark to a bright (or a bright to a dark) image, making dark scenes way too dark to see anything. Seriously, I can't watch movies!

According to my online researches, it is impossible to switch off, because it has nothing to do with the energy saving mode; apparently, this "feature" is hardwired into the firmware.

This problem has been reported since 2010. Here are just a few examples:

Do you think LG will fix this soon?

Thanks for everything.

Hi there,

First of all as long as I experienced Krissserz, these big brands such as LG and others, they don't ever bother to respond to individual customers. And may be replacing your LG5800's LED will fix the issue. But you may hear such discussions on over the internet and may be from your fellows, that the LG's products in 2014, are not of the same quality as they used to be.

Why you don't think about replacing the LCD or the whole LCD screen front assembly? I think it'd help you a lot. If you need to purchase such a part, you may PhonePartWorld.com with free shipping available.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
