This is a common problem with sony it means unplug me or i will explode, it is a protection of the heat sync and usually means that a cooling fan has shorted out. If under gurentee return to Sony for repair if not under guranebntee as is generally the case check on the net for a replacement fan motor - as far as i know sony were sourcing thier fanns from Sunon there is a German based headquarters - just google sunon europe

Sony dav dz100. Disc does not spin.

Please put few drops of WD-40 on spindle motor shaft that sound not spin smoothly.
Spindle motor is located in middle of dvd mechanism that holds and spins disc.
If that does not solve your problem, replace optical block.
Let me know if you need optical block part number.

2 options comes in my mind...
Put software upgrading CD manually in player and let it finish software upgrade process.
If this trick doesn't work, you need to replace digital process board or need to replace on board ROM, if you can.
let me know if you need further info.
