Hi,
I bought the SM and found the cause of the problem (see below). C531, 470UF 25V 85 deg. was low in capacitance. I replaced it with a 105 deg. type. This capacitor (8.9V filter) is on the secondary side of the SMPS transformer which affects the V. regulator feedback circuit.
I will always post an "Update" if I fix a TV, etc. in appreciation to everyone for your help in the past.

I have a Toshiba TV model 27A62 (mfg. 01/03) in my shop (no SM).
