I have a Sega Model 2 HOTD freezing on power up. When I first got the cab, it would do it once every third time I would turn it on and a power cycle would fix it. Since then it has gotten to be every time, and then it turned to completely frozen and would not boot.
-Power supply voltage was 5.07 at the PS (sorry I didn't measure on the chips) and it would freeze on start. 10 power cycles and still frozen.
-I left it on while I was measuring voltages and checking the connectors on the filter board. Swapped in a Golden Tee power supply and the game booted right up. It was set at 5.2V.
-Adjusted the original PS to 5.2V and it booted up right away.
-Played a few games shut it off and the next day it wouldn't start again.
power cycle 5 times and nothing. Leave it on and frozen for 10 minutes, power cycle and on.
-I can consistently get it on now by doing leaving it sit for 10 minutes frozen and then power cycle.
Does anyone have any similar experiences? Caps on the board? Bad chips? Can I swap this ROM board onto another model 2 board and see if the problem goes away?
Any help advice is appreciated.
