Thread: PICSTART+ Powert Supply problem
face BY : mikeKILLspam@spam_OUTwhitewing.co.uk

SMPS startup problems are frequently caused by dried out electrolytics
on the PRIMARY side - the first thing I do with these is replace all
the low-voltage electrolytics on the primary side - there are usually
only one or two,  using 105 deg.C types. This often fixes the problem.
Also, the high-value (100K-ish) startup supply resistor going high is
another possibility.
Secondary-side problems seem rare with small SMPSUs.
