Sony tv kds-r60xbr1 has yellow tint

Sorry to hear this, but your optical block has failed. Sony replaced a ton of these under warranty and then extended the warranty on these SXRD sets so they could replace many more. They even replaced the sets with LCD sets after a class action law suite. This was a "black eye" for Sony TVs and they stopped making the SXRD sets. Your set is vintage 2006 and there is no longer a warranty. You could replace the optical block with a rebuilt one, but the cost would be about the same as getting a new 60" LCD. I would suggest you do the latter.
