The pictures aren't very detailed but I don't see something wrong. Its a good thing you get a blue screen without a cart in my opinion.ok gtsamour i will clean the 2 slots and hope.
thanks for your support i will update you, from the screens you see that all is OK on the PCB?
Well i dont see why not. There are videos on youtube on how to open one without causing damage, its pretty easy. Take photo as soon as you open it so you know exactly how to put it back.If i try to open the cartridge we can see anything can help to risolve the problem?
No, the diagnostic cannot detect such things. I dont think the problem is a cracked solder point of the slots, anything is possible but you have to go with the most probable, which in this case is a bad cart.I have a question can be the problem in the 2 slots, i don’t know for example unsoldered part on the slots? In this case the diagnose test reveal this type pf problems?
