    CHAPTER 3:    Troubleshooting               

                                 

 

Solution (For A50)

：

 

1. Check the power resistor wire connection between the power resistor and LCB (fig-1)                                   

2. Check the Connection wire between consoles to LCB. Try to plug off and plug on connector 

(Page 13 ,CN2 ) 

3. Check the power resistor whether 10KΩ by multi-meter (Fig-2), if not, replace power resistor. 

4. If yes, Replace. LCB.
