PS14 blown –
V9 chipped with Matrix XL 2 about 6 weeks ago. Was playing fine until a few days ago.
It was then switching straight back off after switching on, so I took it apart, took the chip out and tested.
Its now switching on, but just a black screen.
I then tested all the fuses and PS14 has blown.
Anyone got a fuse digram for v9 or v10 just in case this ever happens again and so I know what size fuse to replace this one with.
Fuse diagram for the V9 in the F.A.Q.s & Guides
the PS14 value is 2A in the v9 and V10
i tested the sucker when i partially assembled it back together without screws in it. all worked flawlessly, so i reassembled it with all the screws and didnt bother to test it again since it already worked. my buddy called me that night and said no pic or sound, and no eject or light for eject button.
i said wtf did you do to it!
it was a MXL2 on a V7. i doubt its the chip, i have it installed to the right of the ribbon cables in that little space. (right below the PS symbol on the tray door) im gonna blame the FAT double sided tape that i used. the chip is sitting at about the same height as the heat pad on the chip next to it. that red ?cap? mustve gotten shorted to gnd when i screwed the case together again. arghhhh!!!!!!!!!! im gonna put electrical tape over the MXL2 this time.
so is the MXL2 still any good? hope my problems solved when i replace PS14. ARGHHHHHH!
I always cover over the chip with tape just to make sure nothing go's to earth, may have blown the PS11 and the BA5815Fm chip if its a V7 board.
all the other fuses check out fine, including PS11. therefore the BA is still ok, correct?
if ps11 ok would think BA should to be fine but, check pin 8 on the BA chip is not going to earth if it is it blown
other then this remove MXl2 and see what happens then.
well, i went ahead and replaced the ps14.
i searched around for them, i wasnt happy with the old school glass type, finally found one that looks like a transistor (flat on 1 side, semi circle on the other) and the thing is back to normal.
id take a pic of the fuse if i had a digital cam, i thought i hit the jackpot when i got these, they fit neatly under the metal casing.
they were approx $1 each.
