TRON Power Supply Problem

[tymawrcymru]

Hi All,

When you switch the TRON machine on, you get white and then red alternating flashing screen.

Game wont boot.

The +5V seemed low so I adjusted the V102 pot on the power supply board and it fired into life,

no problems.

However, when I power off and power on again, I get the same flashing screen.

Adjust V102 again and it works.

Any ideas?

Thanks

I will take a pot shot at the PSU 5V pot being flaky and not holding a constant voltage, others will prob have a better idea.

buy the power supply conversion kit from arcadeshop.com and you're good!

When you turned it off and on again, did you read the voltage level again? i.e is the voltage level dropping each time you turn it on even though you previously adjusted the pot?
