Hi Thoma,

Just a little on 228 - no shematic but,

FSP228 3F01
No standby supply on FSP228-3F01 PSU
Solution:   Replaced CS21, CS22, CS28, CS19, Q7 (MMBT4401) with 2N4401, ZD4 (15 Volt Zener).
Zener seemed ok with quick meter check but was acting like resistor when reverse biased. Other parts that may go pop: F1, Q4, IC2 (TEA1532), Q11, Q9, IC1 (L6598D) (Quuq back thread)
 
Whats FSP271  ?   - not seen it  - Chris.
