Hello , my name is Jack
Perhaps I can help you with this problem but first i must say that the symptoms you described point directly to a broken color wheel .
It comes as an ass`y and not the easiest to replace as you would also have to retime it in the service menu once replaced , not exactly what I would call a do it yourself job unless you are the proud owner of a repair shop
That color wheel part # ***** cost around $180 to buy and to have a shop replaced it at home could cost perhaps 350 to $400 .
Here is a link for the best price i could find for this wheel ;
You can find repair shops in your area at the links below , just enter your zip code
Or this one;
This will give you a list of repair shops in your area.
You could give a call to different shops in your area to get an idea of their rates , it pays to shop around.
Hope this help and please take the time to rate my answer positively (use the stars to rate) if that answers your question as it is the only way i get paid for helping you , otherwise do not rate at all , just let me know and we`ll see what can be done.
Note that you can reach me here at any time after rating if you have questions.
