looks to have had lots of work done to it. new caps,fly,v reg, hot, 3 of the big mylar caps right behind the flyback.and has been reflowed.. when turned on the cab. the big white resistor on the side (b+ resistor) has the the red and blue wires on it ... it gets hot.. never hear the HV or degause.... so i am here looking at it.. lookign at it... looking at it... and i stubble across c7.... there are a couple of what used to be legs sticking out but no cap .. just ether clipped or broken off legs sticking out... looks like it takes power or signal to IC1..

would this be the cause of my problems?

now that i am looking at other chassis.. the one i have pictured is missing a little stand up pcb right behind ic1? do they all have one ?

The standup pcb is usually found on the 27" version, but sometimes on the 25". Doesn't need to be there for the 25" unless it came with it originally...

it doesn't look like it was ever there... i finally got around to really looking at the chassis found a lifted broken pad on the flyback... 2 lifted broken pads on the c57/r101 area... repaired those.. will have to test tomorrow..
 
if you have a bad/wrong/missing/hooked up wrong. VR

it will cause that big wite resister cook it's self.

on the little mylar cap i have seen 25" chassis with it and without it.

i have even added it and saw no noticible diffrence.
