Stock Status: Available.

This is a repair service that is performed on our premises. Once booked you will need to either bring or send your machine into us, or you can have us send our courier to collect it - see here. Once complete you can collect the machine from us, or we can ship it back to you for our standard courier delivery charge (applied during the checkout process).

What is this service for?

There are somewhat common issues with some of the graphics cards in iMacs from the Late 2009 to the 2011 revisions which have dedicated graphics cards (all of the 27in and 2011 21.5in models, and some of the higher spec 21.5in 2009 and 2010 revisions).

What is reflowing?

Reflowing is the use of controlled direct heat to the graphics chip in order to melt the solder. This is achieved using infra red pre-heating plates and direct hot air soldering stations with fine temperature control. The graphics card is removed from the machine, the heatsink and old thermal paste removed and cleaned and the board examined. The board is then heat treated as described. The board is left to cool before reassembly and reapplication of thermal paste. A period of GPU intensive testing is then run to test the machine.

How does this help?

The truth is, we are speculating about the underlying problem. We suspect that the solder used in these machines is suffering from problems with whiskers, which are then creating shorts. The reflow causes the whiskers to be re-absorbed, and resolves the problem. But the truth is, we don't know.

We have been offering this service for some time now, and it has a very high success rate in bringing the machine back to life. However it is not a true long-term repair and you should expect the fault to recurr at some point months, or if fortunate years, down the line.

What if it doesn't work?

We offer a 50% refund of the fee paid (excluding any shipping charges) if the reflow either does not resolve the fault successfully, or if it should fail with the same fault within 3 months - optionally can instead reflow the machine again for free within this period. If the reflowed machine should fail after that period, we offer to do the procedure again for half price, but with no additional warranty.

More information on reflows can be found on our blog here, though please note that that article deals specifically with the 2008 machines. Please do contact us if you would like to discuss the procedure further.
