check the fan which not working.

4 times blinking means Fan stopped, power is not supplied on Fan 1, Fan 2 Fan 3 and at Fan 4. Or Fan connector is not attached securely. Cleaning these fans by using a vacuum cleaner can also solve your problem. Sometimes these fans are clogged by dust.

Is the light blinking constantly or is there a long pause then more blinking. If constant check the lamp door switch . Usually it is broken or jammed. If you jumper it and the set comes on that it. 4 blinks is bad fan.

Four blinks is a fan rotation error code which means one of the four fans is not operating properly. Check these fans and replace any found defective.

• Remove the lamp cover.

• Remove the rear cover by removing the 13 screws holding it in place.

• Check the fans.

You may have a Lamp fan that is not turning. You can verify this shining a flashlight in the Fan Exhaust housing and see if it turns when you turn the set on.

I too have a Sony KDS-R60XBR1 tv and the issue that you are experiencing is due to one of your fans in the rear of the tv is not working.  The tv automatically shuts off in protective mode.  Make sure the POWER/STANDBY light is blinking and not the lamp light below it.  Is the power/standby blinking 4 times in red? If, yes then its a fan that needs to be replaced.  If its the lamp light blinking then you need to replace the lamp.  The lamp is easy to replace by ordering the lamp either from Sony for $250 or find it cheaper for approx. $150 from other DLP sources and replace youself by following your manual.  I hope this helps you.

Sorry to say it but this acts like another bad lamp.
