Well i was troubleshooting a Rampage World Tour board tonight and was just about done when i decided to power up my dedicated machine to check some things in the test menu (board i was working on wouldn't output clear video).
Upon turning it on it went through the normal boot test, then black screen then reboot.... Hmm voltage issue, ok, no problem. Go to the back open her up and found the voltage adjustment knob, moved it just a hair and POW "OH F*CK NO!!" jump up and power down, start looking frantically for a blown cap or other component. (as i smelled the Foul odor of fresh ozone)
enter this face:
Do my dismay i found U45 FPGA Game Instruction chip blown wide open. The label on it was nice enough to catch the center of the chip which attempted liftoff and almost succeeded. FML
Lucky for me i keep stock in spare boards and have a complete Parts board for this game which I secured a replacement U45 FPGA which i actually believed to be bad. I was thankfully wrong and the board is 100% right now running. (attached is a pic in my test cab)
Unfortunately I didn't figure out the problem with the board i was troubleshooting as i called it quits quickly after reviving the freshly damaged board.
Rather than even messing around with the old Peter Chu ATX style power supply i'm just going to order a replacement Happ 20amp Power Pro ASAP. Very glad I had that parts PCB right now.
