  • There are various designs of backlights. They typically have a stack of loose components in an assembly. By loose I mean not totally fixed but not too free. They have to free float enought that temperature changes do not cause issues. They also have to not stick, warp, or buckle over time. Harder to engineer then you might think.

    So consider what might happen if for example the top backlight film might buckle some then stick to the back of the lcd. The film might deform which would change its optical properties. Then later thermal cycling might cause release. It might do same elsewhere.

    Not saying this is mechanism, but just example.

    Edit: Keep in mind the LCD is glass, and the backlight components are plastic. Very different thermal expansion coefficients. Then add LED or CCFL lighting and you have a big changing heat source. Add on top of that humidity changes too.



  • Sounds to me like the backlight behind the LCD. They have components which could potentially sag, stick, or warp. White screen is probably best way to see. Also look at various angles. May be more visible at some angles then others.

    Hard to unsee. I know this feeling. I used to work in the industry years ago. Displays are never perfect and hard to unsee things once you see them especially when it was part of your job.






  • Anyone who is not cautious in choosing a partner for the next 60 or 70 years is nuts. This is probably the most important decision you will ever make. We are almost 30 years in and it is great but it was not easy to find someone. Not sure it is comittment exactly. More finding someone that wants a long term partner and that you both like each other and can stand each other over the long run and are heading in a similar direction in this complex world. Lot of people do not seem to know the difference between lust and love too.









  • The leadership is not the government. Leadership varies widely. The actual government workers and departments are different. Lot of very compitent people. There are questions of course. Big organizations tend to grow, how to address. What should be the priorites. Government cannot do everything. Mandates tend to grow. Polotics and money tend to corrupt. Like IRS, rich people do not want to pay their taxes so republicans always under fund.

    If your talking presidents. Trump is the least comperent in my lifetime. Bush 2, first term not really there, second a lot better. Of course Raegon, Biden, and Trump got too old in office. The others back to the 70s which I lived through and was old enough to follow, mostly competent but all had issues of course. I am not rating these on whether I approve of their policies.
