Hi Chris,
That is a capacitor and should read O/C on an ohmeter. Lift one end
and re-check. You might find it's OK. In circuit measurements are
not always reliable !
Hi,
Thanks for the reply. I was thinking about it last night and I
figured it has to be C1006 leaking or shorted to ground. I just
took one end off and checked it - 120 ohms DCR.
Its dead ! Bin it.
I also notice it's slightly charred in one spot. So I will replace
it (and I will probably replace C1005 at the same time. My next
question is what to buy to replace it. It's listed as:
CAP, FXD, CER DI : 0.022 uf 20% 50V
Does that mean ceramic disc? I hope I can find one in that style
locally.
Its not a critical component. 0.022 uf is a common value and 50Vw is
typical. Try RS components or Element 14, Mouser there's lots to go
at.
