["TAFT HAYNES" <taftdhaynes@xxxxxxxxxxx>]

Hello Techs:  Anyone with Winstips 2.0 have anything on my vertical roll 
problem on model# VS-6071  chassis V13,  Mitsubishi Projection tv.  Its an 
in home service call about 25 miles out of town, and I would love to fix it 
on this second trip.

How does that Winstips database work, you pay 149.00 and you get service 
talk free? for how long?
and what do the ups dates cost for the winstips?


Thanks

Dave
