I went thru this a couple of days ago. The repairman change the bulb and my TV was fix in 15 Min. I too have a Sony 60 inch WEGA.

 Now that I know I can change the bulb myself, but there's a hazmat issue on the bulb.

SOURCE: ON/OFF button (red - off and on - green) flashing all the time

it is important to count the number of red flashes, if it is 5 then the lamp ballast board has failed, (part #1-468-798-14) if it is 4 then the optical block fan (# 178706511) is probably to blame, if it is 6 then the thermal fuse has gone bad..(# a1137954a)

The Best Solution worked perfectly, I replaced the XL2200 Sony Bulb and the TV is up and running again!

Thanks for the help.

SOURCE: Green flashes then tv turns off

OMG! My TV has been sitting in a closet for the last three years because I couldn't afford to have it fixed.  I have googled now and then trying to find a cure for its green affliction but never found the right advice until tonight. I can't thank J19666566666 enough!!  I just followed the instructions and presto!  Working TV again! And just in time for the Oscars (which is like the Super Bowl for me).  
The editor in me tweaked the instructions a little...
Its is real easy to fix. There are 2 screws holding the front speaker cover on near the bottom corners (there are plastic plugs covering the screws that need to come out first). Unscrew and remove the speaker cover (pull it out from the bottom a little then sort of down and out to get it loose but be careful because there are wires attached). Next remove the 4 screws holding the particle board panel in place. There will be a cluster of 6 adjustment nobs with a drop of white paint on each one (2 rows of 3 - do not touch the top row). The green is controlled by the bottom middle screw, Using a screwdriver turn it counter clockwise (to the left) ever so slightly (1-3mm) and there you have your TV back. Use the bottom right screw to adjust the red and bottom left screw for blue. 
Thanks again so much!

SOURCE: 5 red flashs on power/standby light on kdsr60xbr1 screen blank,

Thats the error for lamp driver error. Which means the Ballast is most likely defective. You can get the replacement ballast for your model at the following link which comes with installation instructions.
