Hi,
Im new here and im looking for a solution to my problem with my Doosan dnm500.
When i start the machine up it ends the RAM test but gets an error in the ROM test, i have looked for solutiona but all I could find was fixes for ram errors (mostly dust, electromagnetic interferences, vibration or pressure).
This issue fades after few hours of repeated trying to reboot but Ive wondered what could cause it, and if there is another way to boot the machine that might go around this.
Notably, a memory card was replaced over a year ago.
Thanks and have a great weekend.

Fanuc oi-mf series
I replaced the memory but it keeps giving me the same error as the previous one that I have to turn it on and off many times to start it and when I turn it off again it's the same
memory is same as previous same make and model

will you have a phone number with whatsapp or email to send you photos of the control

you have to change the mainboard as the problem is on the CPU
i think you rmainboard is all in one type and you only can remove the FROM/SRAM module,the rest is compact
