Just ca;lled customer service, general line, in my manual. on a sunday. they answered right away and i have a transaction code for one-time service! Am on hold for scheduling of service but i am quitew happy so far.
i have a HL-T5076s. mfg 2007. i don't remember when i bought. maybe sometime 2008. i got 1 white dot a week ago, and every few days i get another. i now have 4 of them. I would call my use as mild-moderate. maybe a couple hours a day in the last 2 years. before that, rare use. I have not yet even had to replace the lamp.
PS- by the way, the reason I am posting is thanks to you folks. I was about to give up. I had performed other searches that suggested that i'd be wasting my time calling, although that is a dumb strategy on my part. at any rate, THANK GOD for you all!

edit- i am at about 30 min total phone time. service scheduling picked up around 27 min and apparently is having some problem with the computer system or something, so i am back on hold while they work it out.
