Tweaking a KV-40XBR800

[freakaftr8]

Thanks for the info Charles, it seems that it's possible that the blanking circuit might need to give the CRT more time before supplying the image. The CRT's are indeed big and when there is a predomantly white screen with text the raster gets dimmer.
On the oterhand my KV-3000R displays excellent whites and no differences in dimming (grid) of the raster when whites with text or just a white background is displayed. Also with regards to focus, it never gets sharp. It's decent but not perfect.
It seems that this set from the factory is being pushed to its limits to drive the CRT.
But dont get me wrong, the picture is nice, and not complaining (especially free).
It's be cool if this set had an hour meter so I can see how much torture it's had.lol

You're comparing a '49 Buick Limited to a '92 Hyundai
