Hello all,
I recently purchased a new Philips 37" FULL HD TV (model 37PFL5405H/12), and so I decided to replay all Playstation my games in HD (after being stuck with SDTV for over 3 years). Every game I've played so far looks amazing... Well, except for one. The other day I decided to boot up Batman: Arkham Asylum. The game itself looks great, but there's a strange green tint over any yellow text in the game, which comes and goes
The problem is only noticeable in parts where there is black in the background.
In other games I've had no such visual problems, though that might be because no other game I have has parts where large portions of the screen are in black (?).
Could it have something to do with the fact that before playing the game, I switched between 720p and 1080p a few times because I wanted to check something (please don't lecture me about how I shouldn't have done that. I know it was a stupid thing to do. Then again, the TV is brand new - I bought it less than a month ago. and therefore it wouldn't make sense for it to have been damanged by my doing something wrong just a couple of times).
Again, other games look fine, videos look fine and TV broadcasts look fine. Even the game itself looks fine. The "green-ish tint" only affects the text.
What could be the cause of this problem? Is there a way to fix it? I've read somewhere that a similar problem is caused when the "CRT" is damaged. What is a CRT? Is it replaceable? If so, how much does it usually cost to have one replaced?
The problem occours after the TV's been on for 10-15 minutes.

Thanks in advance to all who provide aid,
Yotam.
