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.

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

hi, do you know about electronics circuits? you'll have to take them out and check the voltage outputs, especially the one the led is off.before doing this did you try cleaning pins of ram chip?
if you can find new ram replace it to be sure your ram is good.

No, Where are they located, are they on the main board? The slot is not at my shop so I have to keep traveling to mess with it.

Hi, ram chip is located IC 65
but as seen on your photo,the board is clean,pull out the chip and replace it will sometimes secure the contacts. If nothing changes, the chip is probably bad.
With the board pulled out check the voltage of cap C 135,it would be about 2,5 to 3,5 V
Near this cap,there's a white four pins connector, is it connected to another small board? If yes,send me photo,it will probably be another ram board as on another sigma model

Is there a button cell battery mounted on the other side of the board.? I do not see a battery in your photo. Not sure if this model used a battery? But I just had an issue with my SG-50 when I removed the battery and left it out, I would get a RAM ERROR after each time I turned the power off and turned it back on. I Installed a new battery, turned the reset key, twice I believe, turned till the errors cleared and it is working properly now.

I'm not sure about this but if the board does not use a battery and as mentioned earlier maybe it uses C135 as a power storage? It is a capacitor and they do deteriorate from age and no longer function properly.

Ok, I pulled the chips but they were super clean so not sure where the problem is. The thing that has me perplexed it the board to the right behind the wheels has a LED that is not illuminated. not sure where to go from here.


Thanks

Did you check voltage on cap C 135? If you read less than 2,5v,it is not enough to supply the ram, what i usually do is desoldering it and charge it on a 5v power supply unit till it reaches about 3,5V once  done leave it alone for about half an hour check the voltage if it's not decreasing, if so the cap is bad,need a new one, if not put it back and start the machine.
