make sure you've connected everything properly, it may be a lose wire

It sounds like you have a bad Blue Polarizer in the light path. I'm sorry but that is something you will have to contact a service center for. It's not something you'll be able to do yourself, I'm sorry, but that's the best advice I can give you.

Sounds like a possible Bad Light Engine hopefully you have a extended warranty otherwise look for a costly repair

Its magnetic effect on picture tube. Power Off TV for 20-30 minutes then turn it On, hope problem will be resolved. Please also check and remove any speaker or some thing have magnet near by TV.
If color spots are still there, picture tube need to degaussed / demagnetized.

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.

Make sure the pic size is set to full

picture tube is goin bad............

I recently got a similar TV with the same problem i thought my brother had taken something with a magent in it and sat it on top of his old TV when i got it it had the dis color up top right,
Well like most TVs you take a magnet, and it will change the color somewhat,
Well i tried it, tried to get the color as small as possible, carful not to get too close to the screen, i got it pretty close to being gone somewhat, and i turned the TV off, well i turned it back on, and guess what, the spot was completely gone, and never came back,

I suggest to try this ONLY if you have no other solutions to your problem,
im just stating what worked for me, and im not a tech,

Goodluck.,
