I'm the one who originated this thread. I have a KD-34XBR970 set as the family daily driver in the living room. On average, every ~4 months, I've had the "blinking light issue" on startup that I originally posted about. I've been able to solve it by unplugging the set for a short time, then plugging it back in.

I have the genuine replacement chips on hand, but haven't swapped them yet.


Recently, I've observed a new behavior when the set starts up, and I'd like feedback from the experts on it. When the CRT is initially coming up, I see horizontal "streaks" in the lower 1/6th of the screen, as well as the R/G/B colors not aligned in that area. After several seconds once it's warmed-up, these issues go away and the picture looks normal.

What are probable causes of this? Is it repairable? I'll try to remember to capture a picture or video of this.

Thanks!

Recently my KD-34XBR970 set has had the faintest green tint uniformly over the whole screen. It’s most noticeable when the picture is all white or very light colored, and it seems to improve after the set has been on for awhile.

Are there any thoughts on this and what to do about it?

Slow imorovement points to the CRT being a little weak.
The set almost definately has AKB so it adjusts itself. There may be
a way to tweak it in the menus BUT if its OK after warm live with
it.
BTW if you go into the service menus ALWAYS write down the
parameters & save them. Also be sure to exit properly to save the changes.
