I got the error 4SNS/40000001:VDOR on a 2006 iMac (white), what does it mean?

Dear all,


yesterday I notice a whitish stripe (3-4 cm) in the middle of the monitor of the iMac I use at work. The machine is an old white iMac (Intel), 21 inches I think, and was purchased in 2006. Today the stripe was already there, the hardware extended test returned the error 4SNS/1/40000001:VDOR . The machine is apparently working fine. What does this error mean? How soon do I need to contact the Apple Store in my city?


Thanks a lot,


Marco

MacBook Pro, Mac OS X (10.6.8)

That is a voltage sensor error probably on the power section of the logic board. It should not cause a video defect.

According to the MacTracker database, that old an iMac is considered "vintage" by Apple and therefore they will no longer work on it. I had a 2007 MacBook Pro fail earlier this year and was told the same thing. You would have to seek a Mac-savvy, third-party service provider.


The stripe is likely a problem somewhere in the video hardware and those are seldom picked up by Apple Hardware Test. To see if the problem is on the logic board (not worth fixing) or confined the the display itself (maybe worth fixing), attach an external monitor (an adaptor may be required). If the stripe does NOT appear on the external monitor, its in the video cabling, the inverter, or the display itself. If the stripe shows on the external, the video hardware on the logic board is failing.


Neither is a cheap repair--probably more than the approx US$300-450 value of first-gen Intel iMacs†---and your firm may consider retiring that unit after backing up the hard drive contents.
