Hi Jackie,Thanks for the question. My name is Dan.
Your request is a bit outside the scope of this site. Though, I'd be happy to provide a second opinion about the diagnosis... or even help you find a rebuilt light engine (circa $300 usually). Else, consider contacting a consumer/consumer site such as CraigsList or eBay.
Let me know.
I'd hate for you to sell that TV for $200 (unless I was buying it ).
There are 2 very reputable companies that I know of... ModusLink PTS (here) and TriState Module (here). They both rebuild light engines, and resell them with warranties.
As I mentioned, a rebuilt light engine usually runs circa $300.
