how can I tell if my 7jp4 is dead?
I've got a 7jp4 that appears to have fading vital signs. I get a dark gray raster with retrace lines. My screen voltages and HV is ok. Is this just lack of video input, broken cathode, grid, or something else related to the tv itself?
Right now the TV only produces a raster to my knoledge. I've got a bud with a good 7jp4 that he's willing to use to test my chassis, but I just want to get an idea of the life expectancy of this crt.
Any thoughts?
