1: the screws are loose. to fix this, undo the back of your tamagotchi as far as you undid it before (of debugging this is to the microchip thing) and make sure all the screws are as tight as they can be (but don't force them to go tighter than they want to, they might split and THEN your in trouble!
2: the battery is not in properly. to fix this, simily adjust the battery. to test if it is the problem, undo all the screw down to the microchip again. get te battery and put it where the battery goes, making sure the battery is touching the little springy thing at the botttom and bothe the little metal things at the side. these may look like they are just there to hold the battery in place, but they are actually an important part of the circut. look at the screen. the full screen will be working if that was the problem. just do you tamagotchi up again and put the battery back it the right way.
3: one of the wires may have become detatched from the place it's meant to be (PLEASE NOTE: i am not sure if this would really cause the screen to blank, but i decided to add it anyway). at this point you may be thinking "oh no, my tamagotchi is doomed" if this is why it's broken. but don't go buying a new one yet. there is a simply operation which should get your tamagotchi working again. all you have to do is get the wire that has become disconnected and a tiny bit of masking tape, and carefully stick it back in the right spot so the electricity and information can still get through. i have saved my friends tamagotchi by doing this, so don't think it wont work. after this operation, i would suggest that you don't open your tamagotchi up again unless you HAVE to, the wire will become disconnected VERY easily. Of course, if you have a friend in the engenieering business, you could get them to solder the wires back into place, a more permanent solution.
4:it got wet. as with reason 3, i'm not sure this will cause the screen to go cookoo, but its handy incase you get your tama wet, anyway. to fix this, all you have to do is undo ALL the screw (being very care not to CAUSE reason 3 to happen) and leave your tamagotchi infront of a radiator (but not to close, it will melt) on a towel overnight to dry. do it back up in the morning and it should be fine...
5:it got muddy. to fix this, do what you do for reason four, only fefore doing it up, carefully use a pair of tweezers to pick all the clumps of dry mud off the board.
6:it got dirt in it. to fix this, do what you do for reason 5 only you don't have to wait for it to dry (because its not wet)
of course, to avoid reason 4,5 and 6, avoid taking your tama anywhere muddy,wet or dirty!
these problems don't ONLY occur when you are trying to debug
hope this helps you!
