Idea about this one.

Sounds like a connection issue. A tech would try unplug, plugging internal things as a first response. I know some think this is planned and it is. Long ago makers would go for 10 year designs. As the consumer balked on cost, some makers dropped to 7 and then 5 and there are significant cost reductions you can get. Most sets will get more, some will get less but a consumer does not want to discuss design and cost trade offs.

Ask a TV Tech to take a look.

Hello lghater,
Sorry to read about the issues you're having with your 42LH3000.
Sounds like you might also be having a black uniformity issue, albeit a particularly severe one!
LCDs and LEDs are very prone to this regardless of manufacturers! Not that I am making an excuse for what's happened to your set, but to explain an industry wide problem. Plasma TVs are not prone to this.
You may be experiencing a non-uniform pressure on the frame issue. Both the LCD screen and the diffuser layers are somewhat flexible. A slight difference in pressure on the frame of the television can change the uniformity of it. On some televisions, this can be fixed if your issue is caused by a problem of pressure on the frame, you can adjust it by slightly loosing or tightening the screws behind the edge of the screen. Some televisions do not expose the screws however. A small change of a screw can have a big impact on the uniformity of the screen, so be careful if you attempt it yourself. If your TV has an extended warranty on it, it should be covered. Some models are more prone than others to have issues. Even within the same model, some TVs can have more of this issue due to a slight variance in the manufacturing or the shipping process. It might be worth trying to contact LG's Customer Support to set up a diagnostic and see if that is the issue then see if anything can be done or if it would be worth getting it serviced!...IFV

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?
