Yellow spot in middle of screen

Hi there,
We have the same exact problem with the same TV. We've only replaced the bulb once about a year ago. Don't know if it had anything to do with the fact that we now have a large yellow circle in the middle of our screen, which is about 7" round.
We only noticed the yellow mark about 4 months ago.
Hopefully someone will have a solution for us that doesn't cost an arm and a leg. Paid $2100 for this set and are a little disappointed.

Sony 60" LCD projection TV has yellow screen discoloration

I would suggest to try to get this TV fix while still under warranty. Normally the manufacturers give one year.
In regards to the discoloration, there is not much you do but to let the Sony authorized repair center knows about it so they can fix it. Ask them if their work is guarantee as well for how long.
Good Luck.

I would first check and see if any software updates are out on this set, you can call Hitachi, if not that then it could be the engine assemble having problems.
