IRC 3200N screen blanking out

[teckat]

Those Pcb's (sub)Main Controller PCB & SRAM PCB do not come as a package/ they are ordered individually

[charm5496]

the multicast discovery usually causes the machine to reboot itself and I doubt the fuse pcb would be causing the control panel to go blank. I would stick with the items in the main controller cage.

the way to test if this is a multicast discovery issue /power off>just disconnect network -> power up-/wait and see /go to lunch for 3hrs. come back/ ask customer to report

Funny thing is ,
I have never seen the 3200 have a Multicast Discovery issue when it is left ON !!!

the more times u remove & re-seat PCB's as stated- the more issues u run into & or create

the following is for all IR's

the reason for this measuring procedure,>
not all PCB's are installed correctly, they may look OK , but if not seated firm or bent > issues appear (errors,unusual symptoms,communication problems,etc>>>>>

Clean the terminals (both front and back) of the Sub PCB using a lint-free cloth, lightly impregnated with alcohol. Be sure not to damage any of the terminals. If damage occurs, replace the Sub PCB in Question.
After the alcohol has dried completely, hold the Sub PCB firmly and slowly insert it approximately halfway.
You can see this by looking at the mounting holes of the PCB. The mounting holes will be to the
left of the cage frame.
After the PCB is mounted half-way, place the mounting screws loosely in place (approximately 1mm between screw and frame).

Measure between Sub PCB’s. As each PCI slot is lined up, the measurement from one Sub PCB to the next should be equal.

When measuring, do not use the upper PCB of the PDRM-EF-A PCB assembly. Measure the lower PCB as it is connected to the PCI slot.
If all Sub PCB’s are equally distanced, press the Sub PCB into a full mounted position, and then tighten the screw nearest you first.
Then tighten the screw nearest the frame second.
Re-measure and confirm the distance from one Sub PCB to the next.
Once confirmed, re-assemble the Main Controller Cage Assembly Cover and Rear Cover.

You are experiencing an INTERMITTENT problem! In any (electronic) repair work this is the most TRICKY fault. I do agree with chanuk's suggestion though.
_ 99% of all intermittent faults in an electronic equipment is caused by :
1)poor contacts; and these includes loose wires or poor terminal contacts, or even loose connections inside the components itself (chips).
2)Dry solder joints on any of the printed circuit boards.This offers as a high resistance path to the signals/data.
POSSIBLE SOLUTIONS:
Before moving in to replace the boards or components first thoroughly check the above possible causes and correct them if true; re-seat contacts properly and reheat any dry solder joints.
Try all the above possible solutions as suggested by other techs.
Remember to give /post us a feedback so that we can monitor the progress and also continue to learn.

I can't thing of anything other than what has been described earlier by our friendly techs, but if all you have tried and failed. I suggest you try and replace the screen panel board or the unit as a whole and have it tested. Plis notify of any progress.

Goodluck on your copier

All DC goes through this board. Have solved many weird faults addressing this board. If you lose a dc voltage,main,dcon and all other boards wont fire up.Good luck. Sounds like you have addressed everything else

I used to troubleshoot video games in arcades 30 years ago...my most useful tool was freon(when it was legal to use). I would spray a board with it(disconnected of course). Board would cool off,bad joints contract. If this fixed it,i would go over joints with soldering iron. Never failed.Video games took a lot of abuse. Pinballs were the worst(nudging machine)

hey guyz, i wont be able to meet the machine until 3rd of week of march as i was stationed on another location. i am taking notes all of your suggestions and solution and those that are still coming in. Will implement all those once i got my hands on that machine. Will feed back whatever the outcomes are.

Hello, I too am having this issue.

Teckat used an anagram "MSW" it appears I am clueless to what this means my assumption is a micro switch of some sort?

Insight is appreciated, as I start the brain salad surgery on my old friend this week.

Thanks!
