hello, i obtained a tron of which i am having difficulty with, bear with me its my first post. Here is the story ,i started by cleaning out the machine electronics and all, powered it up and checked my voltages there all within .3 volt range.on power up i get white and blue rectangles on the top of the screen,so i checked my roms, my ribbon cables and all was good i then resorted to cutting the purple wire. My results were a screen that flashed and would cycle colors if i reconnect the reset while in play it freezes at the color shown at the time, none of the test switches work on the pcb, the audio amp board also has a shorted amp,and was not connected through any of this.So i purchased a new pcb from quarterarcade hooked it in and i get a half yellow half blue screen with static rain effect, without the reset i get the same cycling of colors with my first board. as a side note the led on the super sound io never flashed or blinked on either board.Next i ordered a switching power supply from arcade shop,assuming it was a reset issue, and with the reset connected on the new pcb from quarterarcade i get squat noting , without i get the garbage from when the reset was connected on the old power supply the half yellow half blue screen. on my old board with new power supply i get a diagonal line of scrolling static like a lighting strike per say, without the reset i get the blue and white squares thanks let me know this is where im
