Trouble Shooting Guide (DVDR520H)
1 Just “HELLO”
1.1 First recognize what kind of “Hello” it is. You have got two types; one with Power
on and one after Power on, when the DVD starts up.
1.2 If the unit takes a long time to complete the power-on process, check IDE
cable (or 4 IDE connector: connecting between Loader & HDD) whether
assembly / connecting properly or not.
1.3 To check the connector between main board and power module had been
asembled / connected properly. ( Fan on rear panel should rotate
continuously ) if there
is no power supplying to main board ( Yellow: +12V <-> Red: +5V measured wth
universal voltage meter ), replace / change another new Power Module.
1.4 Check the FFC (18 pin) cable between main board and display board had
been assembled connected well.
1.5 If after checking above still Just “Hello” do the following:
Replace/change another new Main Board; if still not work,
Replace/change another new DVD writer ( Loader ) if still not work,.
Replace/change another new HDD;

assembled / connected properly. (Fan on rear panel should rotate
continuously) if there
Is no power supplying to main board ( Yellow: +12V <-> Red: +5V measured
with universal voltage meter ), replace / change another new Power Module.
2.3 Check the FFC (18 pin) cable between main board and display board had
been assembled connected well.
2.4 Short the JP8 (on the main board) with jumper,
and then, plug with power cord to check if the text on the LED module had
been lighted on. (Test mode of Display Board had been activated). In case the
answer is negative, replace / change another new Display Board.
2.5 Replace / change another new Main Board. (There should be something wrong
