Iv purchaced a gameboy that has power to the led but no picture or sound.
Iv tested the output from the battery and its outputting 6.4v.
Psu points are
Vcc 6.26v
Gnd 0
Minus -276mv
Plus -151mv
Now i no these outputs are wrong but im getting 6.24v on the board up by the switch when its turned on.
Strangly when i was checking the voltages i shorted the Vcc & ground together and the device started up, screen & volume was working and i was able to use the device, but when i turn it off it wont turn back on, would this suggest a short on the psu or on the board?
