DVD Writer - Blinking Green light

Hardware & Gaming PC Builds, Modding & Overclocking

My friend got a Sony DVD DRU-710A (something like that model) writer. He told me that he inserted a DVD movie his dad got from states. He tried to play the DVD but cudn’t play it right so I knew it is that region protection isue so i suggested him region free tricks and softwares.

Now he complains that the DVD’s region is automatically set to “Region 2 Albania” and the Green LED and the cabinet LED “continuously blinks” and the DVD writer does not read DVD/CDs at all though windows detects the writer.

I told him to try use this tool:

But still no solution. Is the drive dead? only hardware gurus can handle this now :grinning_face_with_smiling_eyes:

Try flashing with the original firmware to see if it works.

@ ferrar!

Did you ask ur friend to change the firmware ?? or has he changed it?? if so then first thing to do will be to restore the original firmware as chaos suggested above.

if not then that means the firmware is original.

first undo whatever “hacks” you had suggested and what ur friend had duly complied with.

Then remove the “upper” and “lower” filters for the drive in the windows registry (if any)

hi chaos and deejay,

the firmware is BYX2 and i see an upgrade is available here BYX3:

shall i flash it?

@ deejay,
in registry the lower filter is:

but i have the blinking problem from boot start and in linux too. so registry is not an isue i guess.

Regards.

yes, you may.
but first check and try to remove any “upper” or “lower” filters entries in the windows registry.
it should be here, HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class{4D36E965-E325-11CE-BFC1-08002BE10318}
check all the entries for this class {4D36E965-E325-11CE-BFC1-08002BE10318} in the windows registry.
edit : ok read your edit hence am doing according to new edited info.
flash to the latest bios and try. if the blinking lights persists try with a different hdd cable …

hi deejay i edited my previous reply

i also refered to these solutions here:

I think i will flash it bcoz the blinking exsists in LINUX too right from when i switch on his PC
