Fidelity CTV 3132 NF
 

This TV was dead but I found 5 parallel i ohm resistors o/c (not
burnt) in the SMPS. Replaced and now emits regular faint clicking
sound.
Anyone got a circuit diagram please? - I've searched everywhere.
The SMPS uses a 16 pin TDA8380A and BUW13 NPN power transistor with a
CNG82A optical coupler for the feedback. What is it safe to try?
Don't think the transisot is faulty.
