Hi, i’m new to this but I just fixed this issue on my own. The camera turned on fine, I was able to see how the orange lights switched according to where I was shooting (daylight, inside, cloudy, etc) but whenever I tried to press the shutter button, the four lights blinked and the red light on the back on the camera turned on.[br]

I opened the camera and found lots of dust/sand INSIDE the camera, precisely blocking the gears that linked the motor to the mechanism that pulls out the film after each shot. Using compressed air I removed the sand, move the gears by hand and made sure that everything run smoothly.[br]
[br]
Then, I assembled everything up and the camera is working fine again. [br]

Hope it helps!
