GE13PF6504 no picture but green splotches

[technoman9]

SUCCESS!

Tonight I installed the new regulator, a new diode in D805's slot, and replaced four capacitors that had opened up. I plugged it directly into line voltage and well-lah! She produced a picture for the first time in ten years.

The picture itself it decent, though I had to turn the brightness and contrast up quite a bit to show well. The color controls are touchy (meaning small changes result in large shifts of color), the middle if the screen is slightly brighter than the upper and lower areas, and the right side is bowed toward the center a bit. I presume some of this is due to the low-end nature of this set and quite a bit due to it's age (I have no idea how many hours are on it).

If anyone has any suggestions on what to check out for these quirks, I'm all ears. Otherwise, thank you for educating me about B+ voltage checks and regulator testing. Another feather in my repairman's cap!

@damen: Yes I did check that mica insulator. The new regulator did not come with one but the old one was in excellent shape when I examined it. I put a thin layer of silicone grease on the new regulator before installing.
