Screen powers off

[kam_]

Hi,

my t43p screen just turns off after anywhere between 3 seconds and 2 minutes. When i press the little switch that usually gets pushed in when u close the lid, and release it, the screen comes back on, again for 3 seconds to 2 minutes

Any ideas what might be wrong?

I just set the brigthness to minimum and it seems ok.

Also the screen is yelowish when it first comes on, then goes white after about 30 seconds. Sounds like something is about to fail?
But what?
