The resistors were good,but I resoldered that 'area'..... unit seems to be
'loading' properly now.
By that I mean,it takes less than a minute for the 'loading',then it goes
into 'auto' which is time set and autoprogramming.
opening the DVD tray does not cause the 'loading' to re-appear.
As far as the DVD Video problem,I found what seems to be a bad connection
On the module under the DVD Mechanism.
After removing the Shield and verifying that I could chill the 'micro' and
cause the Video to go haywire,I had a closer look(magnifier)
at the PCB and found a bad connection at Connector 1801........the small
Black connector opposite the 2 white connectors.
It was the ground Pin. Resoldered it,at it's working for now......need to
let it play.
All is well now.......... time will tell........
