Please help this uk guy PS7 Fuse –
Trying to help another Uk guy on another forum this is what he has said
I used a Magic 3 chip and had a few problems with it soon after installing. It eventually stopped reading any disks. I checked all the obvious things but found nothing with either visual or meter checks. I then removed the chip completely and it still wouldn't read an original disk, however, if I now put in a copy I get the red screen asking for a playstation format disk.
If I put in an original it goes to browser and then disk reading error and stops.
On checking, I discovered the ribbon cable onto the laser was loose and fuse PS7 blown.
I am now hopeful that if I replace the fuse all will be ok.
would the PS7 fuse blow because of this or what other cause would blow it
PS7 is one of the PS2's enigmas. It protects the voltage regulator that turns 12v into 8v supplied exclusively to the game controller (the paddle).
There would be one of three reasons:
- A short occurred when plugging or unplugging the controller at the front panel. Unlikely.
- The ribbon cable connecting the front panel to the mother board has been seated upside down or in some other way mis-placed. Likely.
- Some solder splash or bridge has occurred on that circuit. Possible.
Just replacing the fuse of same value may not be the answer.
