Solved! Inspiron 3662 screen blanking

[jeremy.short1936]

Recently purchased an Inspiron 3662. Everything working fine except screen blanks for a few seconds regularly. They have already replaced motherboard but problem remains. Anyone had similar problems - I note that this model has now been withdrawn from sale.

If this is a new device, you need to get them to either fix it or give you a correctly working one. No new device should give you problems.
