Just recently got issues with my NeoSD AES version. Havent had any issues with it at all, but all of a sudden I get pixel defects.
Notice thats most often in menus.
Some games (Last Resort) wont run at all, reporting "bad contacts... " by the UniBios4.0 and reboot itself.
The contacts I have cleaned, and they are very good condition. After cleaning, reinserting etc etc the problem is still there, the pixels seems to be at the same spots aswell.
Have a NEO-AES 3-5, using a 10V 3A high quality power supply. Velleman. This is what I've used all the time.
Edit: Things I have tested since I posted.
* Resetted the NeoSD with the reset.cfg method.
* Cleaned the contacts again.
* Tried with unibios 3.3.
* Formatted the SD-card.
* Tried another SD-card.
