The picture on my sony bravia 52 in is huge and I cant seem to be able to fix it. On the picture size it is set at wide mode and normal is not highlighted to be able to change it

Try pressing HOME, Then go to SETTINGS From the list, select SCREEN
There are now several options that may be causing the picture to zoom. Try adjusting each setting in the following order, checking if the problem has solved after each change.
Set: DISPLAY AREA to NORMAL WIDE MODE to NORMAL AUTO WIDE to OFF 4:3 DEFAULT to NORMAL
If you are still having problems, you may need to speak to Sony about having the TV serviced as an internal circuit may be broken - if this is the case it may be covered by the warranty.
I hope this helps - if you require more info, here is a link to the Manual for your tv http://www.sonystyle.com/wcsstore/SonyStyleStorefrontAssetStore/pdf/warranty/0451c422be8f7211d50375af6ace50aef8fb6504.pdf
