Imoudu,
Try to use exact voltage or Bit Higher Voltage capacitor or chances are high for rework.

Hectoring and Tayo,
Thanks for your comments,I tested almost all components on board.As to non polar cap I tested their capacitance with dmm meter.The yellow cap read 351.6nanofarad,while the red cap read 208.9nanofarad.Both are out of spec.

In my country a/c national grid can suddenly go high or very low,so we use this appliance to stabilise a/c input when it happens.

replace capacitar 105/630V for a 105/ 400V; is this ok???? or to low???

Interesting article

Sure glad we still do not need those AC stabilizer units on our AC power grid.
