ByteDelight sells thousands of devices annually.
Of course we get in a repair from time to time, and because of that we are able to see some trends and causes in them.
With repairs of DivMMC EnJOY! interfaces, what we see the most (90% of the repairs) is that these have become defective when connected to a ZX Spectrum +2A / +2B / +3.
Sometimes the ZX Spectrum itself also became defective.
We found out that the original non-serviced power supplies are the cause of these defects.
Now we will repair your device that you ordered at ByteDelight.com.
But we can’t prevent our hardware from being damaged by a bad power supply.
If the same power supply will still be used, the defect will occur again.
So we strongly recommend to have your +2A / +2B / +3 power supply refurbished or serviced.
This will include at least replacing the electrolytic capacitors.
We will be adding a refurbishment service for these power supplies soon.
Alternatively we started to produce quality and esthetically cool looking replacement power supplies that you can find in our webshop.
