Sigma W4312 RAM ERROR

(1/7) > >>

TobyOcc:
I have just got in a Sigma slot and am getting a RAM error. I am a arcade guy so this is new to me. Any help would be great. Thanks.

Hi,try cleaning the pins, or maybe the ram chip is bad so replace it. This is what i usually do about ram error. With other machine sometimes the power supply causes this error, check the +5 volt.

TobyOcc:
Ok so I pulled the reels and the boards on the back show the right 2 board led on the last one on the right led is off. Any help there?

I Will reply you later i must go
See you

metex:
Hi,use a digital voltmeter, locate the power supply unit,you will see some indications at the output section, +5v,+12v,-12v... Check the outputs
If you cannot do that, post photos of boards
