2) Remove screw (ST1T∅ 4 x 10s 2 pc.) of the

 

P. C. board

 

 

upper part of the front cabinet.

 

 

(Soldered surface)

 

 

• If removing the inverter cover in this condition,

 

 

 

P.C. board can be checked.

 

 

 

• If there is no space in the upper part of the

 

 

 

upper cabinet, perform work of 2.

 

Be careful to check the inverter because high-voltage circuit is incorporated in it.

3)Perform discharging by connecting e, d polarity by discharging resistance (approx.

100Ω 40W) or plug of soldering iron to e, d

Be careful to discharge the capacitor because the electrolytic capacitor cannot naturally discharge and voltage remains according to trouble type in some cases.

NOTE :

This capacitor is one with mass capacity. Therefore, it is dangerous that a large spark generates if short-circuiting between the e,d polarity with screw- driver, etc. for discharging.

4) Remove screw (ST1T∅ 4 x 10s 2 pc.) fixing the
