    just purchased a 2009 dual processor tray comes with 6x 1GB memory from ebay

    Plug in to my macpro 4,1 (updated to 5,1 firmware) press the power button, white led stay on all the time, fans running normal, no chimes, no boot, no display. tried remove all the pcie cards and hdds, only left gt120 GPU still no go.

    Any idea? currently plugged in my previous processor board im typing now. could be a defective board?

    did not see any error led on the board.

    White LED, do you mean the one what above the power push button?

    My last experience with a dead CPU tray is very similar to your situation, but have white screen (on the 27" Apple Cinema Display) rather than "no display".

    If you can still return the tray and get all money back, I will do that ASAP rather than diagnosis.

    If that's not an option for you, I will remove the heatsink, remove the CPU, check the sockets, and check the North Bridge. By the way, you bought the dual processor tray, which CPUs in there? Are they the stock / de-lidded CPU?

    Looks like you bought a daughter board without CPUs. Did the buyer specify that it came with the CPUs included? Depending on how much you paid for it I'd say you've got to either

    a) Get a refund
    b) Buy some processors for that tray

    It looks like there are damaged pins in the pictured socket. So I think (A) is the only option.

    there is a processor, i think might be the shipping damaged the heatsink caused the pins damaged. well im trying to see if there is a way to replace a new socket. ebay seller accept refund but shipping it back its on my own cost. and 10% restocking fee. problem now is shipping it back from Asia to USA kinda not cost effective.

    If you don't want to ship it back, and have a stable hand. You can try to fix the pin by yourself. I never do that by myself and that sounds high risk as well. But from memory, at least a member here did perform that by a forceps + magnifying glass, and the repair was success.

    I don't know if shipping can cause this kind of damage, but IMO, it's hard to just damage 1-2 pin at the middle of the socket if the CPU is there and the heatsink was installed properly. Especially not only one side, but both socket A and B. However, this kind of damage is not uncommon when someone try to install a pair of normal lidded CPUs. I suspect the seller try that upgrade, end up damage the tray. So he put the original CPU back in and sell it, pretend nothing happened.

    I rarely buy stuff on eBay, and not very familiar with the rules. Is it common that the buyer need to pay the return shipping cost if the product is actually not as described by the seller? If I were you, I will ask the seller cover the return shipping cost as well. Otherwise, I will ask the credit card company to file a dispute.

    Those 'pins' are bent over pieces of metal. If you try to clean with a q tip, the fuzz will get into the pins (thats what happened to me--had to pick the hairs out with a tweezers). Maybe if you put contact cleaner on the end of a toothpick. I would call it defective and return. Otherwise, a cleaning might help. With that delidded crap, these are a pain in the butt to work with. The socket doesn't hold the processer in place, so you have to be very careful when putting the heat sink back. Also, of course the cpu sticks to the heat sink when you pull it off, so that's another messy hassle.

    I saw discoloration on a number of pins, and no, this does not happen during shipping.

    Since the product is damaged the seller cannot charge you a restocking fee. He also has to cover the return shipping costs: http://pages.ebay.com/help/buy/return-item.html

    I would not pursue any sort of repair type remedy. The seller sold you a lemon, best to move on and get a good one. If the pins were discolored due to high current or some such, there very well may be other parts on the mobo that are fried. By taking it apart, you open yourself up to his claims that you broke it by taking it apart, but I think with ebay you are protected against such nonsense.

    These pins look burnt not bent.
    Return the tray, don't even bother with fixing it.

    Shipping back at your own expense is always the risk that you take with purchasing on eBay. You will never get your return shipping refunded. All you can expect is whatever you paid including shipping. Even if it was damaged in transit (which seems unlikely) it's still the responsibility of the seller who should have insured the package against damage or loss. Likewise when you return it make sure that it is insured & tracked. Return it & get a refund either from the seller or if they won't play ball raise a claim with eBay/PayPal.

    This tale shows that it's just not worth buying a dual CPU tray to upgrade a 4,1 or 5,1. For the price you might as well sell the single CPU system that you have & buy a working dual CPU system & avoid all the hassle.
