This is the reply I received from Samsumg when I complained about our problem to "customer service":
In reference to your email; thank you for taking the time to share with us your experience with Samsung. We sincerely apologize for any inconvenience this issue may have caused you. However, we regret to inform you that we are unable to accommodate your request for warranty coverage at this time due to the expiry of your limited warranty. We have confirmed with our Quality Control department that the model you own does not exhibit any widespread issues that may cause concerns. Furthermore, your specific unit does not have any service history that we may review for further consideration of your request. Therefore, we regret that if you wish to have your unit repaired you will be required to cover all necessary service costs. If you have any further inquiries regarding warranty terms and/or conditions please contact our customer care line at 1 800 SAMSUNG.
Thank you for your time and we appreciate your cooperation.
I am compiling a list of forums, starting with this one that show their customers have a problem with the DLPs that seem to be from the 2006 models usind this chip. Any assistance would be appreciated, just past the link to any forums you have come across. I'm also going to send a letter to the Canadian BBB with this information on it.
