I've been working on a std res K7000, I've done a cap kit and replaced the flyback. The picture looks good, I get a shimmy occasionally, not hula, and the monitor will stay on roughly 15 minutes and go into HV shutdown. B+ is steady at 131.5v. Is this too far out of the 123v spec to cause HV shutdown? I can't recall which thread, and I currently can't find it, where it was discussed that the C36 cap could be bad and causing this. I'm also wondering if I should go ahead and replace IC4 while I'm at it. I've read through the sticky about K7000 and Randy Fromm's flowchart and am basically just asking for advice on what I should attack first or if I am heading in the wrong direction.

Thanks!
 
Well, you can check C36 to make sure it IS the 6100pf cap. And then just go over all of your traces, especially those circled in the sticky pic. Sounds like it's heat related...
 
I will double check C36 and make sure, I'm pretty sure it is the 6100pf. I will also double check the traces. If it is heat related is R301 being affected? Is 131.5v too high for B+?
 
If it is a 19", then it should be 123. i think the 25" are 130. 131 for a 19" is a little high, but I think it would still work. usually those fluctuations in B+ are caused by solder/trace issues...
