I am dealing with a 19 k7602 a generic k7000. the monitor is going into high voltage shut down. I pulled d10 and it came on so I quickly turned it off. I replaced c 57 still high voltage. (when c57 was replaced I did not notice that flux had bridged a trace on the cap so that it was in essence shorted. I replaced ic4 I still had high voltage and when checking b+ I saw the voltage drop down the monitor came on for a few seconds and then the slo blow fuse burned out. I have checked the hots for conductivity center pin to ground and have removed it to be replaced since it conducts. I wanted to check the b+ without it and and both legs of the resistor read 160 volts without the hots in I was wondering how to test ic4 in case I blew it again? after this first voltage test I noticed c57 was shorted so I cleaned it up and tested the cap and it was reading correctly. fired up the monitor and the voltages were still too high and r 105 was getting extremely hot. are these voltage too high because I have no hots? and is r105 getting hot because my voltage is too high? what should I do


ps I think r105 is a thermal resistor to stop the degaussing coil? is this supposed to get hot and cut the voltage?

my flyback was blown resistor 104 which is under c57 had come loose from the board and I beleive had shorted once to chassis under neath blowing the flyback and hot. voltage regulation was failing due to bad connections of r 104 once this was fixed voltage regulation was perfect and the monitor came on
