can we see terminal log ?
changing head without properly diagnosing the problem was not a good idea...

Probably it was not heads to start with.

You need to check Terminal log, I imagine you will see LED:47 or something similar error.

you need to short read channels during initialization and try to retain T> where you can look to correct any issues such as relocation or translator but bear in mind that this model uses additional defects for translation that is not preserved with translator regeneration

Hi
Thanks for your reply
Can you give me more details about how can I short the read channel?

You really should post the terminal log here to be sure the right advice is given to you - at this stage there could be a number of issues taking into account the physical repairs undertaken and the initial failure resulting in constant BSY

unfortunately, the terminal log page is empty and does not contain any information

Then most likely you do not have correct connection to terminal - you should at the very least see 'Rst' message on power on.
