Otherwise there is a full recall on all 50XBR1's and 60XBR1's for ANY video issue.
But the bullentin I do have on that is Confidential due to the amount of claims SONY could recieve. But here is a sample of the bulletin.

Models: KDSR50XBR1, KDSR60XBR1

Subject: Optical Block: Warranty Policy and Part matrix by serial number.

Resolution: As part of Sony’s commitment to quality, Sony is announcing that it is extending the limited warranty (parts and labor) for optical block replacements on the models listed above until October 31, 2008, regardless of purchase date. Authorized servicers should follow the normal process for warranty claims for this issue.

Most but not all of these sets have a reset---with set off and Sony remote hit display, 5, volume up, and POWER.

Set should come on in the tech menu---hit 8 on the remote and you should see the word RESET IN RED, then hit enter to complete the reset.

If the green band was there before it may be a optical light engine bad, these sets are well known for this.

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...

  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen A2 slightly.

Yesterday after playing video games for a couple of hours my son tunrs off the set. He returns 45 minutes later turns the set on as usual the green power light flashes 3 times followed by a red indicator...

Red flashing 6x is a thermal fuse,I have serviced hundreds of these models and have never encountered 7x.If it is flashing 7x try unplugging the power for 2-3 hours and try it again.If that doesn't work you will need probably need a K-board.

Power light flashed red 4 times then repeats no pic,new bulb/fan!

Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.

Sony kds-r50xbr1 turns itself off and then green light blinks 52

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.
