I'm sorry to hear that you're having a problem with your DLP.
I'd recommend contacting the Samsung customer service center. Unfortunately, I can only assist on a limited basis for repair requests, but explain your situations and see if they can assist. They can be reached at 800-SAMSUNG.
If they can't assist, ask for a transaction number and post it here.
I am having a snow storm of white dots on this TV (50+). I understand there is a fix for this problem. Please contact me with any steps I have to take to resolve this issue.
