I have a Compaq 6820s (HP-branded) with a 17" LCD screen running Windows 7 SP1. A few days ago, I noticed that when I woke up my computer from hibernation or booted it up cold, the screen would be a funny reddish tint, then slowly adjust to the correct color. But now, the screen randomly turns itself off every so often.
It's not the power settings. I changed them to "never" turn off the screen and it still happens. Plugging in an external monitor works, so it's not the graphics driver. What actually works to get it back on are one of two things:
1) I can hit the power button to put the computer to sleep, then wake it back up.
2) From the external monitor, I can change the display resolution of the LCD screen. Once I change it (and change it back), the display works again, at least for a while.
What's going on, here? I've priced a replacement screen on eBay for $60ish and feel comfortable with doing the repair myself, but want to know that replacing the screen will fix the problem.
