A. Check the resistors or resistor-array adjacent to U201 Pin200~208 and
Pin61~70 or IC to see if there is any hollow soldering or cold soldering.
B. Check the resistors or capacitors of J601, U601, U201, or U302, or those
adjacent to IC to see if there is any hollow soldering, cold soldering, wrong part,
or misplaced soldering.
C. Check to see whether J902 is damaged.
D. If the above actions are not working, replace the Main Board. If it is still not
working, replace the loader.
DVD ROM
A. Check the loader to see if it can’t read. If so, replace the loader.

Main Board
A. Remove the cover. Check to see if it is caused by mis-assembly.
B. Check the resistors or capacitors of J801, U801, or U802 on the main board, or
those adjacent to IC to see if there is any hollow soldering or cold soldering.
C. If the above actions are not working, replace the loader. If it is still not working,

replace the main board.
T13Disc drive scratches disc
Main Board
A. Check the resistors or capacitors of J601 or U601 on the main board, or those
adjacent to IC to see if there is any hollow soldering, cold soldering, wrong part,
or misplaced soldering.
B. If the above actions are not working, replace the loader. If it is still not working,
replace the main board.
DVD ROM
A. Check the loader to see if it is the cause of disc scratching. If so, replace the

B. If the above actions are not working, replace the loader. If it is still not working,
replace the main board.
T15Head does not work
Main Board
A. Remove the top cover, check the 30-pin flat cable in the system to see if they
are correctly plugged to the fixed positions, or re-plug them.
B. Check the resistors or capacitors of J601 or U601 on the main board, or those
adjacent to IC to see if there is any hollow soldering, cold soldering, wrong part,
or misplaced soldering.
C. If the above actions are not working, replace the loader. If it is still not working,
replace the main board.
T16Spindle does not work.

A. Remove the top cover, check the 18-pin flat cable in the system to see if they
are correctly plugged to the fixed positions, or re-plug them.
B. Check the resistors or capacitors of J801 or U802 on the main board, or those
adjacent to IC to see if there is any hollow soldering, cold soldering, wrong part,
or misplaced soldering.
C. If the above actions are not working, replace the loader. If it is still not working,
replace the main board.
