It's a very common problem on Philips PSU's. Replacement type is not
critical. Just about anything of similar rating, intended as a smps
secondary reccy, will work perfectly well in my experience.

just tried a BY255, but got erratic operation and overheating -
probably couldn't handle the frequencies of the SMPS..... today I
bought an exact replacement schottky so will post back when
installed. Ben

I guess I wasn't clear enough when I said

"intended as a smps secondary reccy".

The *exact* type is, as I said, not critical. The *generic* type of course
*is*. A secondary-side reccy in a smps *must* be a high speed job, typically
a Schottky type, as you were originally asking about. Sorry if I implied
otherwise ... :-)

no worries Arfa, my misunderstanding. Anyway I fitted an SB 560 and
all seems well. thanks for all the responses!
