My 2006-07 iMac wouldn't start after a power outage; I found Wintech through a Google search and brought my machine to them, describing the problem and asking for diagnosis/possible repair. A couple days later, their Apple specialist told me that the serial # on my computer indicated that it was obsolete by Apple's standards, so couldn't be serviced. I asked him to at least open the back to check the diagnostic LED lights, but then I called back within a half hour to ask him to not do anything, I'd just pick it up before they closed that day.
It still cost me $136 (and the computer self-corrected after I got it home that evening!); the tech said that he hadn't actually opened the back (he'd been about to do it when I called back to cancel my work request), so I'm not sure how whatever little he did do added up to $136 in charges, even allowing for the time he spent thinking about the problem and looking up the serial # information; the minimum charges any service business might have, etc.. From what he told me, no actual physical work was done aside from plugging the machine in to confirm my service issue that it wouldn't come on. read more
