I haven't had this problem with my EX-8000. If you want to reset it, though, you need to press "5" and "8" while powering it up, not "5" and "6". The latter initiates Voltage Reference adjustment mode (hence 'VrEF' being displayed). Reset will clear all sound program data, of course!
To check that the delay is completely out of action, on any program set 71 and 72 to mid-point values and increase 76 from 0 to maximum. If you can't hear any difference, the delay isn't doing a thing. If you want to dig around, it's on board no. KLM-775 on the DW8000 [probably the same on the EX8000 but I can't open mine up to check at the moment] -- see page 22 of the DW8000 service manual for the schematic.
It looks to me as though the delay board is permanently in the signal path even when not actually adding a delay, so given that you're getting an output at all, things can't be too serious with it!
Hope this helps,
