National TR-5090A TV schematic needed.
"Little Steve"
** Is the disk draw moving sluggishly ?
If so, the nylon gear lubricant has gone sticky.
WD sprayed into the affected areas does wonders.
Might fix all the symptoms.
I doubt that the disk drawer is the cause of this problem,
** As do I - kindly read what I wrote to Bob.
more likely it's
either the laser diode going down or a problem with the sled.
** The " sled " uses the same sticky grease.
Must be 20 gear wheels and other bits involved.
Either too much wear, or bad lubrication.
** Bad grease is my hunch.
Seeing as 100 % of CDP 101s have that exact issue.
Shame you have no clue.
