Fm Towns Help - Intermittent cd reading issues - Suspect heat issue

Hey guys,
I was recently given a FM Towns console to check over and try and get going.
Its strange.
The console works fine when its cold and as long as you do not switch it off from the intial cold boot it reads disks fine.
If you play a game for like 5 minutes then switch off and change the disk the disk access light will not flash at all and it will not read any disks.

I have cleaned the laser and checked over what I could and replaced all the CAPs on the CD board just in case but I am still getting the same issue.
I have checked for any components over heating on the CD board but everything seems normal.

i am sure the CD laser itself is fine and is something else wrong with it.
Any suggestions? Not much information on this console.
Thanks!
