OB has been replaced 2x in my KDSR-60XBR1. Lamp also replaced 2x.
Since the second OB, everything has been running much longer than with the original and the first replacement without the reappearance of any green blobs.
That being said, I did set the TV to "High Altitude" which makes the fan run at a higher speed.
Maybe this has something to do with it? i.e., keeping things cooler.
Anyway, I'm watching TV last night, and I notice the picture abruptly drops in brightness, as if I turned the Iris control down a couple notches.
I turned off the set, then back on, still dim. I then unplugged the set for a minute, turned it back on and brightness was back to normal for a couple hours, then noticeably dropped again. Tonight, the drop now happens within a few minutes after cycling power. It's still watchable, just disconcerting.
First question: Is this a sign that my lamp needs to be replaced?
The last couple of times I replaced the bulb, if I remember correctly, I just noticed the picture started to gradually get dim over time, nothing like the quick drop I am seeing now.
Second question: How do I check the current lamp hours? I followed this procedure found online for this model:
To read the Lamp and Panel time:
Press the "JUMP" key [3 times] to enter the DE-micro service menu
Press the "2" key [9 times] to show the Panel and Lamp hours.
I also read to reset lamp hours do this:
Press "3", "MUTE", and "ENTER" keys in sequence.
Out of curiosity (or stupidity) I hit 3, then MUTE, but must have done something wrong, because my entire screen turned red.
Hitting Mute changed numbers on the screen but it continued to stay red.
In a panic, I hit power. The TV turned off after a few seconds. When I turned it back on, it was still red...
In another moment of panic (and a few expletives), I unplugged the set for a minute. When I turned it back on, things were back to normal.
Needless to say I am not trying this again until I can confirm the correct steps.
Third question: Did I mess anything up by doing this? Everything appears OK now, but I am worried that I inadvertently wrote data somewhere in the service menu that may cause a problem.
I am hoping that whatever I may have done was cancelled when I cycled power.
It's certainly no joke when people say "don't mess with the service menu"...
Fourth and final question in reference to the back story: After I noticed the initial drop in brightness, I went into the video menu to check the Iris and Brightness settings.
I noticed in the Advanced menu that the Green Bias and Green Gain were still turned almost all the way down from when I started experiencing the green blob problems last time.
Could this in fact have an effect on OB life? In other words, could this be why the second OB replacement has lasted much longer than the original and the first replacement?
I didn't notice much of a difference when I put them back to their defaults, so I am wondering if I should just leave them where they were.
Any help, advice, tips, etc. would be most appreciated.
Thank you for reading!
