C.
Check the resistors or capacitors of J601, U301, or U201 on the main board, or
those adjacent to IC to see if there is any hollow soldering, cold soldering,
wrong part, or misplaced soldering.
D.
If the above actions are not working, replace the Main Board.
DVD ROM
A.
Check the loader to see if it is not stable (any condition that some of the discs
can’t be played). If so, replace the loader.
DVD DISC
A.
Check the Test Disc to see if there is any serious scratch or ring shape, circular
shape scratches, if so, replace the Test Disc and test again.
T08
Power on unstable
Main Board
A.
Remove the top cover, check all flat cables in the system to see if they are
correctly plugged to the fixed positions, or re-plug them.
B.
Disassemble U301F/W. Replace it with a good one or re-plug it to see if the
symptom will disappear.
C.
If the above actions are not working, replace the Main Board.
T09
Abnormal sound in the machine base (Power on abnormal sound)
DVD ROM
A.
Check the loader to see if it is the source of the abnormal sound. If so, replace
the loader.
T11
Disc drive can’t read (NO DISC)
Main Board
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.
T12
Disc drive no action or locked
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,
