I would suspect stuff other than the player:

- is the battery good?
- is the charging system good?
- what is the local temperature?
- what voltage is arriving at the sled through your wiring?
- what is the gauge of the wire (end to end) supplying, and earthing your sled?
- is the gauge of the wire on the sled earth the same or larger than the power feed?
- how many hard disks in your player?

Why does having this icon come on irritate you? It does have a useful function.
