I found some time to use my new B&K 467 CRT Restorer/Analyzer today. In fact, I did 5 monitors. The steps for setting it up and using it were really straightforward, and it was even easier for me because every monitor used the same CR23 adapter, and a 6.3V heater setting. I started with this tube:
This is from a monitor that stopped working after I did a cap kit on the chassis. The plastic insulator was burned and brittle, and literally fell apart when I pulled the neckboard off to cap the chassis. When I initially hooked up the BK467, all three guns were in the red. This was one of two tubes that required the draconian REJUVENATE function. After rejuvenating all three guns, readings were all midway into the green, and colors were tracking well! I was happy about this because the screen has almost no burn. It will make a nice monitor for someone. Does anyone know where I could buy a replacement CR23 insulator?
While I was adjusting my Defender, I ran the color RAM test and discovered some errors (vertical bars):
I'll re-run this test after swapping in the JROK board; I would expect that to fix the problem.
