hard to belive, 6 screens blank! but I am an Engineer anyhow
Very unlikely to have 3 faulty DCU’s!! but if the cooling is not working for some reason, it will be a different story.
Its very easy to have the cooling inlets blocked (dust)!
Quick fix: pull the CB’s for a couple of minutes and get the FLT deck temperature down.

This is caused by one (or more) DU sending corrupted data back to the DMC or another DU. This corrupted data is not recognised by the system and thus causes a hardware reset....hence the blank screens. Recovery, if the system does not auto-recover, is (as I suspect you already know!) to turn off all the screens and reset then sequentially one by one until the duff unit is isolated.
Not looking forward to this one I must say, but AI claim they have a fix ready now. Interesting to see how long it takes to be installed.

Yes the reset were done acc. to QRH " turn off all the screens and reset them sequentially one by one " . Even though this procedure din`t bring up a faulty unit.
I have also heard that the ISIS (stby. instr.) could be the problem ??
You say that AI have a fix ready. Do you what and when ?

The 'fix' is a software update, available now. My company has started the update procedure and I expect all affected aircraft to have been done within a week.
As probably the first to report the problem, which, as far as I am aware, only affects EIS2 equipped aircraft we are doing the update in advance of the expected mandatory SB.

I don't know if the 747 has these screens, but it would make sense that any new production ones would, since I believe the 777 uses them. Boeing would use any new technology in all their products, as would Airbus. However, it wouldn't necessarily mean that the screens are from the same manufacturer. They might have a different supplier.

The only reason ISIS comes in to it is that the MEL has been made more restrictive re: inop data e.g. attitude, IAS, etc. on the ISIS which basically limits you to day VMC if you have ISIS functions inop.
However, the fix is available in two steps, first fix being uploaded, next one should be avail in July.
