I have probably 100 AM27C020's here that will not burn with GQ-4X any longer. I have tried the burner on 2 different pc's just to make sure it is not the software installed.

They all verify blank, but the second you click burn, the light blinks like crazy, and will not burn and gives a write error.

Any ideas?

If possible, try any other brand 27C020.

It could be chip problem.

If it still does not work, then you can send 2 chips to support@mcumall.com to find out the problem.
