Ok, to update my recently built premium problems... there are some things they are aware of...
If your recently built GZ premium has a building entrance opto that has failed for any reason, they think they might know why and will adress it if you call support. They have a couple of recommendations that depend on your symptoms and how they failed. Call and put in a ticket.
If you are getting random lockups, turn off the power, remove the micro SD card from the CPU board, (NOT the SD card, which is physically bigger and holds the game code image) and restore power. Does it boot and play now? If so, replace the micro SD card with a blank, new micro SD memory card, the same size as the one you removed, and at least one with a minimum Class 10 speed rating. No need to format it, it will be detected and formated when you turn on the machine. The micro SD card is scratchpad storage for Insider Connect communication, it is designed as replaceable scratchpad memory that gets written to and read from during IC communications and instead of using expensive ram, or the game code SD card, they opted for cheap uSD memory so if read/write cycles wear it out after a while, operators can restore IC communications by simply swapping in a new memory card. Now if they would have just used a better supplier of micro SD cards...
And put in a call and a ticket... they will not probably spend that extra $0.05 for a better uSD card until they find more than 15% - 20% failure rate, so lets tell them were to stick the latest batch of uSD's, shall we?
