I have a Sony KDS-R50XBR1 that has no picture. When I turn on the TV, the green Power/Standby LED light blinks for about 30 seconds, then turns red and blinks five times. The Power/Standby LED repeats the cycle of blinking red five times. While the Power/Standby LED is blinking green the fans are on.

Hi,
If Lamp light blinks then it is lamp that is near to end of its working life.
If standby light is blinking then it is some thing else, when did you replaced lamp in tv last time?
Thanks.

Yeah, it is not lamp problem. Check fans in tv as one of fan is stopped for some reason and causing problem.

Hi,
It is clear symptoms of weak lamp in TV, replace lamp to correct that problem.
Lamp replacement is easy and written in user manual of TV.
Please buy Sony original lamp for TV safety.
Thanks.

bad lamp

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.

Just replace its Lamp and procedure is written in user manual of KDS-R50XBR1
