I will be happy to request that your case be reviewed. Thanks for posting your number. I'll send that up this morning.
I got a Samsung DLP HLT5689SX/XAA and begin to have white dots 2 months ago. I called Samsung but they told me my model is not cover in the service recall but have the same problem that many samsung dlp. My DLP is in like new condition with a battery backup to protect from voltages and don't understand how can't be broke in around 2 years.
I called service center with my ticket # 4007541770 and said that the repair with cost like $500-600 with part and labor.
My family will be very greatful if Samsung can review my case.
