This is a TP-600 that I still like. But it has a display problem.
Everything is fine to boot up. But after about 10min or so when it
gets warm, the display goes away. It turns into grey and no image. But
external display always works. If I let it cool for a day or two, it
comes back on.
Since the external display has no problem, this is not video card
related, but LCD related. I just do not know what part goes wrong.
Some people mentioned LCD backlight, but I'm not sure.
I also look to replace the entire LCD, but I do not know if this will
solve the problem.
