If anyone's looking for the DLP chip to DIY the repair. I've got one ordered from Samsungparts.com that I didn't take out of the box. I opted to take Samsung up on their part warranty so that I could have the bench warranty from the tech should something go terribly wrong.
Part # 4719-001981 Cost (including priority insured shipping) $166
