#KILLER INSTINCT 2 PC PORTABLE UPDATE#
Since my last update all of the parts I ordered came in I'm not touching that thing, cut my losses and bought a new one. I attempted to adjust the output and as soon as I touched the pot the PSU started making this high pitched electrical charge noise, like a bomb ready to explode, I quickly shut it off and the charge noise even continued for a few seconds after the power had been cut.
I should have tested this before going through the trouble of replacing the fan. I was getting 5.6 on the 5V line and 11.3 on the 12V line. Noise is gone but then I tested the voltage.
#KILLER INSTINCT 2 PC PORTABLE FULL#
I had a box full of brand new PC fans so I opened up the PSU cut out the old fan and spliced in the new one. Plugging it in it was clear that the cooling fan was making the racket. So I had pulled the PSU out of the machine to bench test it. I shot a quick video since it's hard to describe noises:
The power supply sounds like it has a bad fan, the monitor is making a very disconcerting buzz, as is one of the speakers. So EVERYTHING seems to be making bad noises on the machine. I tested the PCB in my working cabinet to confirm that it did what I expected it to do. It probably just needs a fresh flash but I figured it was good enough to test this cabinet and if something goes wrong and damages the board, hey, it didn't work anyway. I grabbed a broken Mortal Kombat 2 PCB I had, it boots and beeps and most of the EPROMs fail CRC, and then it tries to launch the game but then just shows some scrambled graphics and reboots. it was as if someone was planning on completely gutting this machine and then after unplugging everything decided it was too much more work to remove all the screws and just left it. absolutely every connector inside the machine was unplugged, I even had to plug in the connectors that went between the neck-board and the monitor chassis. Wanting to keep working, but my hands still cramped from trying to scrub paint I decided to check out the electronics, I mostly had my fingers crossed that the monitor worked. I think I should be able to fill and touch up the marks that were made for the gun holster. You can also see above the now, uncovered front art work.
