key takeaway: due to the abuse these resistors took when the crt display was new over the course of time when the crt display was young, assume they are burned out with the age of these monitors today! important: do not wear any grounding straps; electricity chooses the path of least resistance and your esd protection will become the ground.
Unless updated, these units have reached end of life of various components, which fortunately are replaceable. I highly recommend that you contact Eddy Voland as I and others on this forum have used him with excellent results. While a "tests good" CRT may buy you some time, unless the vulnerable components are replaced, it will fail.
