104z issue - no output!

I'm not getting any signal at all from the mix or effect outputs of my 104z. It's the same when in bypass.
The input gain lights up so I know signal is going in.
Has anyone else experienced this problem?

Are you using the correct power supply?
CS has told me that it is possible to blow an output IC, so that it sounds distorted if you use an ungrounded socket, or poorly wired connection, or if the polarity is reversed going through your pedals.
Open up the bottom plate and see if everything is intact or if there are burn marks.
There have been all kinds of problems with the early delays, because they crammed too much stuff in a too tiny chassis. There are jumper pins from the daughter board (the upper one attached to the mother w/ extra BBD's) that touched the metal chassis in many of the models that were distributed. This causes all sort of problems from weak delays to no delays to no output whatsoever. It can be cured with a bit of technical knowledge and patience. Me, I just took it to my friend who is an electrical engineer; and he fixed the problem 123.
Look deeper in the threads for the answer.

Thanks for the reply. I have done a search but nothing mentions no output at all.
I don't think mine is an early model but I will open it up to check for any obvious damage.
If I can't see anything I'll probably add the MF-104z to a few bits of gear that I'm going to have repaired.
