It's going into protect. Unhook ALL the speakers and see if it still shuts itself off. If so, then it will have to be taken in for service.

If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.
It's one of the power amplifier channels which has gone faulty.
I just found this out after having this problem with my AVR-1906.
I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).
I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.
Just waiting for them to arrive.
An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.
Hope thats of use!

Hi, this is a power board issue. remove the cover and make sure that this unit doesn't have blow fuse. if the fuse is fine, you will then need to replace the integrated power/ main board.

Did you try to reset the unit? Resetting the unit has fixed every problem I have ever had......turn off unit.....hold down A+B at the same time then turn the unit back on...hold buttons for roughly 3 seconds....Let me know if it works.
