DCS Verdi Encore Faulty any help advise appreciated

Hi All,My DCS Verdi Encore which i have owned for 10 years has gone faulty.
The disc loading tray seems completely dead and will not open at all
(If physically opened still no reaction from open/close command)

The unit displays “none encore” on start up, can't remember if this is normal ?
When pressing the eject button I hear a relay click but no action at all.
I have dismantled the transport and checked for obstructions or a loose or snapped belt etc but all is OK.
The Loader mechanism is a Philips A97SL and has a Philips PCB control board with the numbers 3139 243 31374 01
After many hours research i found that a Philips DVD 625/051utilises the exact same loader mechanism.
So i purchased one from ebay for £2.80p LOL
The Philips A97SL transport can be removed within minutes from this dvd player

So i placed the DCS Verdi Encores A97SL loader mechanism inside the Philips DVD player and it works perfectly opening/closing and playing CD's and DVD's.So i know that the loader along with its 3 motors and laser are working fine.
I suspect the fault could be within the Philips servo board part number 3139 243 31374 01 But i have been lead to believe that this board contains control software which is DCS only ? can anyone confirm this ?
Any help would be much appreciated.
Best RegardsDave
