Recording DVD unresponsive

Panasonic DMR EZ25 , no known history. ps voltages agree with manual slow to respond to buttons like open/close and will not play discs , will go through the sledge/platter sequence before ejecting, laser light present. Most of the time just says please wait. Will not respond to the almost inhuman hand-span 3 button push at power-up to go into service mode. Will respond to forced power off of 10 second push of power/standby button and go to presumably flashing clock of 0:00 that does not advance to 0:01 I've reseated all ribbons and before ESR'ing caps , and exploring rear of main board, any ideas of anything specific to look at

Well that was an interesting exercise in fingertip manipulation . Fathomed (accidently ;-)) how to release the central area of the deck then remove the 2 sled slide rods and then remove the laser assembly. Now know it is type RAF3332A. Then get inside the optics, all without disturbing any set-screws for slide or optics I think, and reassemble. The 45 degree mirror was filthy with dust and even a curl of hair right at the centre, if it was the outlet lens that was that dirty then a CD/DVD player would work. Not yet fully reassembled and powered up yet
