Help with my Namco Exceleena monitor

[Prairied1ll0]

Hey Guys

I have the Blue EX machine and I have an intermittent problem with the vertical sync going out. It seems to not hold and comes and goes.

Could this be a cap going bad? Does anyone know what the Serial number would be on this Nanao monitor. It's in service so I haven't double checked it.

Thanks for any help.

i had the same probelm recently with a nanao ms8-26,i found a few caps leaky
i will check the positions when i return to work on tuesday but they are all near the video input plug and very close to a large resistor which i believe due to heat causes the caps to go after time
the other possibility is the sync module going faulty

Thanks for any assistance! I'll probably be able to get the serial number tomorrow.
