I have a portable Panasonic DVD-LS91 player that is not working. All I see is the screen flicker on start up and a red indicator light that flashes at the front of the unit. The DVD disc that I put in does not spin as if there were no power. I can not figure out why this will not operate. Possibly the only thing I can think of is that it does not sense a dvd disc in the machine
I am a little lost with words and I am not sure where to start looking for this fault. I have downloaded the PDF manual to look at the troubleshooting section but with no joy there either.
This player was not a cheap unit when new and I would like to keep this for future use. I am fairly good in electronics and testing of componets but this I am lost as to where to start.
Is there some one out there who can direct me further in the right direction i would greatly appreciate this.

If only I'd have a schematic drawing here then I might stand a chance. Unless someone else here has experienced the same problem
