Good day all.
I though I would spend my Christmas holidays to try and get my FP3NC with Dialog 4 up and running. I was unfortunately stopped dead in my tracks!
I always had this issue with the machine that when it is switched on, the display would look nice and crisp (running and external monitor through the BNC). After a couple of minutes, the lettering would start to "vibrate" and get fuzzy. Like there is some electrical interference. I knew it had something to do with temperature, as it just got worse the longer the machine was on.
Anyway, while it was shaking, I tried to wiggle some of the PCBs in the console, to see if it might be a bad solder joint that moved under temperature. I tracked the culprit to the NCR53 board. I also know that that is the CRT board, and surely must have something to do with the display. I then removed the board to inspect it, and was shocked at the condition of the board. I can see that it had numerous repairs done to it, and to the state where a lot of the tracks and solder pads had some damage to them.
I thought I would attempt to re-solder some of the joints that looked suspect to me, so I did. Problem now is, that after my attempt to repair is, stopped it working completely, or so I think!?
After the re-solder exercise, the machine refuses to power up and initialize. I also realized that LED 2 on the NSV90 board is now off. LED 5,6,7,8 on the NPP90 (cnc has not yet reapond) is also now on. So I think the real question is, is the NCR53 board responsible for the machine not initiating and showing the error on LED2 (PC-internal emergency stop), or could there be something else at fault? Maybe if someone knows whether a missing or broken NCR53 will trigger this error?
See attached photos of the board damage.
Thanks, and hope to get some guidance!
