Dram Memory Test Failure - 12 APs Any fix?

[wethd]

Over the summer 12 of our 1252 Aironet AP's stopped working and all Ethernet/Radio/Status LEDs are RED. This appears to be a boot loader error due to dram memory test failure.  There is nothing when I console it, and have tried radios from other ap's. Also tried no radios. Everything I have read comes to the same conclusion that they are dead.

Anyone have any ideas that might revive them or may have caused 12 out of 32 to die after 3 years of wonderful service?

Thank you for your help

There's a hardware design fault on the AP1250.  If you have a valid Service Contract, Cisco will replace them with 1260.

I've got tons of dead 1250 that stopped working in the last 12 months.
