I had a similar problem on my hls5086w 3 blinking leds lamp not lit and could hear the wheel spin, I removed the color wheel and the wheel would spin with little effort by hand, had a look at the Hall effect sensor (wheel RPM sensor) which is attached to the color wheel housing and found the wire insulation had melted back and the wire was exposed and frayed and some strands were shorted. Probable cause heat from the lamp. Replacing color wheel with housing fixed the problem.

Before you buy a new color wheel. I would suggest you Google “How to replace hls color wheel” fixyourdlp.com has a good guide. Do you have the skills for this? I would also suggest you wear thin cotton gloves when you handle the color wheel housing, to prevent contamination of the glass from the oil your fingers. try to spin the wheel should spin freely
There are two connectors on the housing one for the color wheel motor and one for the to the hall effect (RPM) sensor. Does it look burned or damaged?
Pictures tell a thousand words.

Tip: When troubleshooting Never assume anything!
