Got a defender pcb set in for repair and was wondering if anyones seen this before
Before asking yes getting correct voltages ect
Boots up goes to rug patten then second patten black screen reboots owner told me he changed all the rams to 4164 a while back and been working fine since until thic hsppen one day He tried a known good video pcb and still does the same issue.
Each time on either video pcb fitted 4 LEDs on rom card come on when it gets to black screen then resets i cant find any info on this type of fault so thought i would ask here
Any ideas
