It is possible that the laser has gone, the part you require is:
Sanyo SF-P101N CD Mechanism - 16 pins (there are 15 pin versions available which have the same product number, the two versions are incompatible)
i have found the part on Ebay (UK) for less than £5, the shop that sells it also suggest replacing the flexible strip that connects that mechanism to the circuit board, the strip costs £2 and replacing it would seem to be a very sensible idea seeing as you have to completely strip the unit to replace the mechanism.
My UD-M31 is in bits on my work bench at present, awaiting the arrival of a new mechanism, i'll post again if replacing it solves the problem.

The disc is loaded upside-down in the disc rack or the disc is dirty or scratched, try another disc and make sure the top side (label side with printing) is facing towards the back of the rack, away from you. The bottom or data side should face out towards the front of the rack. If that does not work then your laser picups inside may need cleaning. Make sure your disc is clean and now scratches.

Hi, I have had exactly the same problem, I have tried three different M37DABs and three Believe CDs by Katherine Jenkins. Unfortunately I dont have a solution, but thought Id let you know its not just your CD player. I hope this can be resolved. Let me know if you ever resolve this problem. Thanks

Self-powered would work but it would have to run on full-range amplifier (from the speaker posts) or Line Level signal (from the OUT RCA jacks) because this unit has no Sub-specific output. It's no bigge as the sub would naturally discard the higher frequencies via its own amp's and speaker

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.
Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.
