Don't get me wrong, I love my kds-60a2000, but I feel I must report my experience getting the intermittent (yet recurrent) fan error fix on this TV. From what I've read, this problem has occurred for small models in this series and for the early Bravia SXRD models.
It took my Sony premimum service tech a full 2 weeks to arrive with the replacement part despite the fact that I told him about the 4-flash sequence and likely need for a fan replacement on my first call. He told me that Sony shipped 5000 kds-60a2000's with bad fans. He said these came from a bad batch that were not making proper contact somewhere around the fan motor and fan blade.
I'm afraid I'm not 100% clear on who manufactured the bad part since he took this with him. I was either a Nidec (made in Vietnam) part OR a Sony part. The service tech gave me a 883586031 Sony DC fan as a replacement part (search internet for deals, this runs $22). He said this replacement part was a better designed fan than anything every used in the kds-60a2000 production line and has been used the Bravia production for the last 2 years. He said early model Bravia did use the faulty fan though, so Bravia SXRDs may also experience fan related problems.
My problems began amost exactly 30 day after my purchase (just after my money-back guarantee expired).
To add to the fear, I did hear the NEW fan seize (and then start) on start up after the power was inadvertently disconnected by the service guy during the starting sequence. I don't know, but crossed my mind that the fan motor could be damaged by the controller if the TV is started at the time the fan is slowing to a stop (just after it automatically shuts off). Based on this fear, I will carefully only power up my kds-60a2000 either immediately after it went into stand-by or long enough after it went into stand by that the fan has already shut off. I'm concerned that there maybe a design flaw here. At the very least, it looks like Sony used some unreliable parts in the kds-60a2000 for some period of time. My built is in August 2006. And again, to support this,the service tech wrote on the service receipt: "Fan defective. Replaced defective component".
So, my feeling is that if your Sony SXRD surprisingly, wonderfully, snapped out of a 4-blink "fan error" with no hardware change, then you are likely not home free. Instead, you have a part (or maybe parts) in there that have failed and will likely fail again down the road. You probably aren't better off until you get the new fan part (883586031) installed in your set.
Again, though, I love picture of my set when using the HDMI inputs though, so I'm still a happy owner of this model.
