Seems like my car does not want to be healthy. Just yesterday I fixed CLP and today, I have this LCD problem.

I do not have pixels missing or anything. LCD itself is good.

When I start my car first and in parking, LCD shows all the lines fine. Then when I change the gear to R, it goes blank. In N, it is okay again, but is blank in D. WTF?

 

There's a button under the wiper stalk that turns it on and off. If your car came with a manual, you should take some time reading it. There could be other few things that the car has you may not know about.
