Question about Sony KDS-R50XBR1 50" HDTV
I'm Sony tech and can help you out.
Symptom shows that lamp is weak in result and causing problem.
As you said, lamp has been replaced but problem still not solved.
Let me know about replaced lamp, is it Sony original or any low price lamp?
If it is low cost lamp then buy Sony original to fix the issue and if lamp is Sony original than problem seems with ballast supply board that provide high voltage to lamp. Ballast supply board need to be checked/ replaced to solve the problem.
Let me know if you have additional question.

There is a very good chance that the lamp is causing the problem. You might want to replace the lamp to keep from having to call for service.If the problem continues the blink codes are provided to the service technician as a starting point to look for the problem.In this case, it is certainly a hardware failure. There could be many reasons for the same such as Faulty video out, CRT drive is faulty or G2 is improperly adjusted.This needs to be taken care by a technician.
However,if you have experience in repairing electronics, could read schematics, know how to use soldering iron and multimeter and would be able to keep all precautions, revert and i would be able to provide you some pointers.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
