BENQ TH681+ Problem with lamp or color wheel?

Looking for some help. When i power up my TH681+ the power led goes green, the fans power up etc but then the lamp led goes solid red.

Looking at the manual (page 52) it says this means CW start fail

I opened up the projector and powered it up with the lamp out and the color wheel clearly visivle. When i turn it on the color wheel does spin but stops after about 2 seconds. I tried plugging in the lamp and it did exactly the same thing.

The wheel seems free when trying to move the inside ring with a cotton bud. No dust or anything inside the projector that i can see

My question is really has anyone seen this before? Does it need a new color wheel? Could it still be the lamp? Anything else i could try?

Any help appreciated
