This thread helped me replace my OB about 5 years ago...thanks for that... but now I have a new problem. No picture, no sound, just 5 red blinks. Any suggestions?

Five red XBR2 means "lamp driver bad", aka ballast.

Fault indications in any set with a lamp are not always reliable in the case of "bad lamp" or "bad ballast". That's because all that lies between the two is a ~5KV pair of wires that are very difficult to monitor with 5v digital electronics.

As always, start with a physical inspection of the lamp. Consider what make of lamp it is and how many approximate hours are on it.

Chuck,


You seem knowledgeable about the bulbs in these sets. Have you seen a correlation between putting in a new bulb and hastening the failure of an OB?


As I said earlier, I have held off putting a new one in as I thought I recalled from years ago that it seemed to be the case.


Thanks,



BJBBJB

I can say that in my personal experience with my XBR2 that I had excellent picture for 3 years, above average for the next 2 years, then replaced my bulb, picture went back to excellent for 1 week and then I developed the green globs. Had to replace the OB at that point. Picture went back to excellent...until recent lightning strike.

I have checked numerous online sites for the ballast. Part # 1-474-010-11 and all say out of stock. Anyone have an idea? I'd like to repair my TV instead of buying a new one. Thanks,

I have a problem with 1080p input that I wonder if anyone has a solution for. About 2 yrs ago I had the optical block refurbished by John Breton. Similar experience to most here: several months waiting (about 6) but I finally got it back and installed it. I wasn't too upset because I had previously called Sony and got the discounted Sony 65in LCD set which is great. However I still use the XBR2 70 quite a bit in a different room. The 1080i input has a feature that you can disable, DRC. The DRC processing creates very strange screen artifacts with extensive color "smearing" (hard to describe) but basically the image is unwatchable. Turning off the DRC clears that right up and the image is actually pretty great. However in 1080p mode I get the same artifact caused by the DRC processing but there is no option to turn it off. Does anyone know a fix for this ie in the service menu or something? The set is watchable in 1080i and I don't want to brick it. I thought the 1080p mode is supposed to bypass that. I tried game mode but that doesn't clear it up either.

Interesting issues you are having. I appear to be having the same thing with my set. I thought the issues may have been related to my HDMI input so went to OTA antenna and still have the problem.

How are you putting the set in and out of 1080i mode?

UPDATE: Sent you a PM with the following...

I just posted in the 2005 SXRD thread about some issues I am having with my set. Gradients look terrible, as if the TV is trying to process the image, making it look somewhat like very poor HDR, with bad artifacts where smooth gradients should be.

My issues may have occurred after going into the settings to adjust black and white levels using the AVSHD 709 videos. Is it possible that my going to extremes within the settings triggered something with DRC? I'm hoping I can figure out how to go back to 1080i, or whatever you describe in your thread, to turn off "DRC" again.
