Golden Tee 2021 not working

(1/1)

Hozz76:
I have a golden tee 2021 machine that I bought that used to be in a bar. It worked perfectly for several weeks after I got it, then weirdness started. If you would hit the ball too hard, the machine would reboot itself. It did that for a few rounds, but the quit altogether.

It turns on, fan runs (so doubting power supply issue) there is no video, the motherboard never beeps, and the button lights never flash as though it is trying to boot. I took the RAM out to see if i could get it to beep that it was missing memory, but never beeped there either.

My suspicion is that itís a fried motherboard. Anyone seen this scenario or have thoughts on something different?

try and reset the cmos by removing the battery and jumping the jumper to the appropriate pins to start.

ive had a couple mobos bios chips go bad this last couple years necessitating a removal of the IC and reprograming the bios bin to a new one (using a ch3414a programmer and standard intel bios bin.)

The system in those is just a PC with some addon hardware. More often than not if you have an issue like that the first thing to look at is power. I would pick up an ATX power supply and try replacing that before you do anything more complicated.
I just got a silver strike cabinet and the setup of connecting a 4 pin ATX power through a daughterboard off the motherboard to power the IO is IMMENSELY stupid. This just SCREAMS 'imminent failure' to me and pretty much everything related to arcade machines that I have touched thus far has absolutely ridiculous power supply configurations.
Poor power will make an IC do all kinds of weird things. Clean up all the wiring, make sure your grounds are tight, replace the PC power supply, test it again. If you still have issues move on to components.

it's not so so bad on those IO boards, typically in these IO boards and in the BBHpro IO boards, the first thing the 5v power does is used to power a LDO linear regulator... its regulated down to 3.3v or 1.2v for the mail FPGA chip power. the raw 5v and 12v is usually used to power audio amps and user lights and whatnot where the power really doesn't matter if it's off a bit.
