My original review of the TV was negative due to a problem of dimming during dark scenes. But few days ago Sony released a software patch to correct the problem and it worked for me. Now, the auto dimming can be turned off by setting the "Adv. Contrast Enhancer" to Off. Also, even when it's turned On, it doesn't behave like it did pre- patch, it now dims gradually rather than abruptly and it doesn't dim as much as it did before. Thank you very much Sony, I'm updating my rating to 5-star.
I'm very happy with the TV now that the auto dim is fixed. If you own the TV and having problems with the dimming, go to the support section of Sony's site to download the patch and the instructions on how to apply it. You will need a USB thumb drive formatted in FAT32, but if you don't have it, Sony will mail you one if you call their customer support.
