EOS 90D stopped working

[TonyCornfield]

My 90D stopped working today. Firstly the rear display looked normal but if wouldn't take a picture. Now nothing on rear display, but top display still working, whether power is on or off! Changed battery no different. Cleaned lens connectors, no different. Nothing works except top display which won't turn off.

Any suggestions please?

I just meant I had to get rid of this 90D.  Luckily I had an old 70D in the closet that I can depend on.  I'm not sure what I'll get, but it'll have to be Canon because of my $1600 lens.
