re: K6100 problem with HV section

Thank you Bill.  Well now I'm confused because I'm looking at the drawing from the manual and the location in the drawing where R913 should be does not look the same as my HV board.  It's a slightly different layout.  And....try as I might...I can't locate anything labeled R913!

There are several components in that general vicinity of the board that are in different locations than is shown in the manual.  So I'm guessing it's a different revision of the board.  Do they all have an R913??

Thanks again,

John

Since you typed ZD901 twice, I assume that the first instance was intended to be ZD900.  Since you replaced that already
as well as C909, and there's still no voltage at the 555, then replace R913.
